[147] It is found in the Bakh[s.][=a]l[=i] MS. of an elementary arithmetic

which Hoernle placed, at first, about the beginning of our era, but the

date is much in question. G. Thibaut, loc. cit., places it between 700 and

900 A.D.; Cantor places the body of the work about the third or fourth

century A.D., _Geschichte der Mathematik_, Vol. I (3), p. 598.

arithmetics, following the Arab custom, always put the 0 after the 9,

suggest that the 0 was derived from the old Hindu symbol for 10?

[200] Bayley, loc. cit., p. 48. From this fact Delambre (_Histoire de

l'astronomie ancienne_) inferred that Ptolemy knew the zero, a theory

accepted by Chasles, _Apercu historique sur l'origine et le developpement

des methodes en geometrie_, 1875 ed., p. 476; Nesselmann, however, showed

(_Algebra der Griechen_, 1842, p. 138), that Ptolemy merely used [Greek: o]

for [Greek: ouden], with no notion of zero. See also G. Fazzari, "Dell'

origine delle parole zero e cifra," _Ateneo_, Anno I, No. 11, reprinted at

Naples in 1903, where the use of the point and the small cross for zero is

also mentioned. Th. H. Martin, _Les signes numeraux_ etc., reprint p. 30,

and J. Brandis, _Das Muenz-, Mass- und Gewichtswesen in Vorderasien bis auf

[Greek: o], without the notion of place value, by the Greeks.

[211] Of course the earlier historians made innumerable guesses as to the

origin of the word _cipher_. E.g. Matthew Hostus, _De numeratione

emendata_, Antwerp, 1582, p. 10, says: "Siphra vox Hebraeam originem sapit

refertque: & ut docti arbitrantur, a verbo saphar, quod Ordine numerauit

significat. Unde Sephar numerus est: hinc Siphra (vulgo corruptius). Etsi

vero gens Iudaica his notis, quae hodie Siphrae vocantur, usa non fuit:

mansit tamen rei appellatio apud multas gentes." Dasypodius, _Institutiones

mathematicae_, Vol. I, 1593, gives a large part of this quotation word for

word, without any mention of the source. Hermannus Hugo, _De prima

scribendi origine_, Trajecti ad Rhenum, 1738, pp. 304-305, and note, p.

305; Karl Krumbacher, "Woher stammt das Wort Ziffer (Chiffre)?", _Etudes de

[213] Fazzari, loc. cit., p. 4. So Elia Misrachi (1455-1526) in his

posthumous _Book of Number_, Constantinople, 1534, explains _sifra_ as

being Arabic. See also Steinschneider, _Bibliotheca Mathematica_, 1893, p.

69, and G. Wertheim, _Die Arithmetik des Elia Misrachi_, Programm,

[214] "Cum his novem figuris, et cum hoc signo 0, quod arabice zephirum

appellatur, scribitur quilibet numerus."

[215] [Greek: tziphra], a form also used by Neophytos (date unknown,

probably c. 1330). It is curious that Finaeus (1555 ed., f. 2) used the

form _tziphra_ throughout. A. J. H. Vincent ["Sur l'origine de nos

chiffres," _Notices et Extraits des MSS._, Paris, 1847, pp. 143-150] says:

"Ce cercle fut nomme par les uns, _sipos, rota, galgal_ ...; par les autres

_tsiphra_ (de [Hebrew: TSPR], _couronne_ ou _diademe_) ou _ciphra_ (de

[Hebrew: SPR], _numeration_)." Ch. de Paravey, _Essai sur l'origine unique

et hieroglyphique des chiffres et des lettres de tous les peuples_, Paris,

1826, p. 165, a rather fanciful work, gives "vase, vase arrondi et ferme

par un couvercle, qui est le symbole de la 10^e Heure, [symbol]," among the

Chinese; also "Tsiphron Zeron, ou tout a fait vide en arabe, [Greek:

tziphra] en grec ... d'ou chiffre (qui derive plutot, suivant nous, de

l'Hebreu _Sepher_, compter.")

[216] "Compilatus a Magistro Jacobo de Florentia apud montem pesalanum,"

and described by G. Lami in his _Catalogus codicum manuscriptorum qui in

bibliotheca Riccardiana Florentiae adservantur_. See Fazzari, loc. cit., p.

5.

[217] "Et doveto sapere chel zeuero per se solo non significa nulla ma e

potentia di fare significare, ... Et decina o centinaia o migliaia non si

puote scrivere senza questo segno 0. la quale si chiama zeuero." [Fazzari,

loc. cit., p. 5.]

[218] Ibid., p. 6.

[219] Avicenna (980-1036), translation by Gasbarri et Francois, "piu il

punto (gli Arabi adoperavano il punto in vece dello zero il cui segno 0 in

arabo si chiama _zepiro_ donde il vocabolo zero), che per se stesso non

esprime nessun numero." This quotation is taken from D. C. Martines,

_Origine e progressi dell' aritmetica_, Messina, 1865.

[220] Leo Jordan, "Materialien zur Geschichte der arabischen Zahlzeichen in

Frankreich," _Archiv fuer Kulturgeschichte_, Berlin, 1905, pp. 155-195,

gives the following two schemes of derivation, (1) "zefiro, zeviro, zeiro,

zero," (2) "zefiro, zefro, zevro, zero."

[221] Koebel (1518 ed., f. A_4) speaks of the numerals in general as "die

der gemain man Zyfer nendt." Recorde (_Grounde of Artes_, 1558 ed., f. B_6)

says that the zero is "called priuatly a Cyphar, though all the other

sometimes be likewise named."

[222] "Decimo X 0 theca, circul[us] cifra sive figura nihili appelat'."

[_Enchiridion Algorismi_, Cologne, 1501.] Later, "quoniam de integris tam

in cifris quam in proiectilibus,"--the word _proiectilibus_ referring to

markers "thrown" and used on an abacus, whence the French _jetons_ and the

English expression "to _cast_ an account."

[223] "Decima vero o dicitur teca, circulus, vel cyfra vel figura nichili."

[Maximilian Curtze, _Petri Philomeni de Dacia in Algorismum Vulgarem

Johannis de Sacrobosco commentarius, una cum Algorismo ipso_, Copenhagen,

1897, p. 2.] Curtze cites five manuscripts (fourteenth and fifteenth

centuries) of Dacia's commentary in the libraries at Erfurt, Leipzig, and

Salzburg, in addition to those given by Enestroem, _Oefversigt af Kongl.

Vetenskaps-Akademiens Foerhandlingar_, 1885, pp. 15-27, 65-70; 1886, pp.

[227] In the 1484 edition, Borghi uses the form "cefiro: ouero nulla:"

while in the 1488 edition he uses "zefiro: ouero nulla," and in the 1540

edition, f. 3, appears "Chiamata zero, ouero nulla." Woepcke asserted that

it first appeared in Calandri (1491) in this sentence: "Sono dieci le

figure con le quali ciascuno numero si puo significare: delle quali n'e una

che si chiama zero: et per se sola nulla significa." (f. 4). [See

_Propagation_, p. 522.]

[228] Boncompagni _Bulletino_, Vol. XVI, pp. 673-685.

[229] Leo Jordan, loc. cit. In the _Catalogue of MSS., Bibl. de l'Arsenal_,

Vol. III, pp. 154-156, this work is No. 2904 (184 S.A.F.), Bibl. Nat., and

is also called _Petit traicte de algorisme_.

[230] Texada (1546) says that there are "nueue letros yvn zero o cifra" (f.

3).

[231] Savonne (1563, 1751 ed., f. 1): "Vne ansi formee (o) qui s'appelle

nulle, & entre marchans zero," showing the influence of Italian names on

French mercantile customs. Trenchant (Lyons, 1566, 1578 ed., p. 12) also

says: "La derniere qui s'apele nulle, ou zero;" but Champenois, his

contemporary, writing in Paris in 1577 (although the work was not published

until 1578), uses "cipher," the Italian influence showing itself less in

this center of university culture than in the commercial atmosphere of

Lyons.

[232] Thus Radulph of Laon (c. 1100): "Inscribitur in ultimo ordine et

figura [symbol] sipos nomine, quae, licet numerum nullum signitet, tantum

ad alia quaedam utilis, ut insequentibus declarabitur." ["Der Arithmetische

Tractat des Radulph von Laon," _Abhandlungen zur Geschichte der

Mathematik_, Vol. V, p. 97, from a manuscript of the thirteenth century.]

Chasles (_Comptes rendus_, t. 16, 1843, pp. 1393, 1408) calls attention to

the fact that Radulph did not know how to use the zero, and he doubts if

the sipos was really identical with it. Radulph says: "... figuram, cui

sipos nomen est [symbol] in motum rotulae formatam nullius numeri

significatione inscribi solere praediximus," and thereafter uses _rotula_.

He uses the sipos simply as a kind of marker on the abacus.

[233] Rabbi ben Ezra (1092-1168) used both [Hebrew: GLGL], _galgal_ (the

Hebrew for _wheel_), and [Hebrew: SPR'], _sifra_. See M. Steinschneider,

"Die Mathematik bei den Juden," in _Bibliotheca Mathematica_, 1893, p. 69,

and Silberberg, _Das Buch der Zahl des R. Abraham ibn Esra_, Frankfurt a.

M., 1895, p. 96, note 23; in this work the Hebrew letters are used for

numerals with place value, having the zero.

[234] E.g., in the twelfth-century _Liber aligorismi_ (see Boncompagni's

_Trattati_, II, p. 28). So Ramus (_Libri II_, 1569 ed., p. 1) says:

"Circulus quae nota est ultima: nil per se significat." (See also the

Schonerus ed. of Ramus, 1586, p. 1.)

[235] "Und wirt das ringlein o. die Ziffer genant die nichts bedeut."

[Koebel's _Rechenbuch_, 1549 ed., f. 10, and other editions.]

[236] I.e. "circular figure," our word _notation_ having come from the

medieval _nota_. Thus Tzwivel (1507, f. 2) says: "Nota autem circularis .o.

per se sumpta nihil vsus habet. alijs tamen adiuncta earum significantiam

et auget et ordinem permutat quantum quo ponit ordinem. vt adiuncta note

binarij hoc modo 20 facit eam significare bis decem etc." Also (ibid., f.

4), "figura circularis," "circularis nota." Clichtoveus (1503 ed., f.

XXXVII) calls it "nota aut circularis o," "circularis nota," and "figura

circularis." Tonstall (1522, f. B_3) says of it: "Decimo uero nota ad

formam [symbol] litterae circulari figura est: quam alij circulum, uulgus

cyphram uocat," and later (f. C_4) speaks of the "circulos." Grammateus, in

his _Algorismus de integris_ (Erfurt, 1523, f. A_2), speaking of the nine

significant figures, remarks: "His autem superadditur decima figura

circularis ut 0 existens que ratione sua nihil significat." Noviomagus (_De

Numeris libri II_, Paris, 1539, chap. xvi, "De notis numerorum, quas

zyphras vocant") calls it "circularis nota, quam ex his solam, alij

sipheram, Georgius Valla zyphram."

[237] Huswirt, as above. Ramus (_Scholae mathematicae_, 1569 ed., p. 112)

discusses the name interestingly, saying: "Circulum appellamus cum multis,

quam alii thecam, alii figuram nihili, alii figuram privationis, seu

figuram nullam vocant, alii ciphram, cum tamen hodie omnes hae notae vulgo

ciphrae nominentur, & his notis numerare idem sit quod ciphrare." Tartaglia

(1592 ed., f. 9) says: "si chiama da alcuni tecca, da alcuni circolo, da

altri cifra, da altri zero, & da alcuni altri nulla."

[238] "Quare autem aliis nominibus vocetur, non dicit auctor, quia omnia

alia nomina habent rationem suae lineationis sive figurationis. Quia

rotunda est, dicitur haec figura teca ad similitudinem tecae. Teca enim est

ferrum figurae rotundae, quod ignitum solet in quibusdam regionibus imprimi

fronti vel maxillae furis seu latronum." [Loc. cit., p. 26.] But in Greek

_theca_ ([THEKE], [Greek: theke]) is a place to put something, a

receptacle. If a vacant column, e.g. in the abacus, was so called, the

initial might have given the early forms [symbol] and [symbol] for the

zero.

Roche, _L'arithmetique_, Lyons, 1520.]

[241] "Decima autem figura nihil uocata," "figura nihili (quam etiam cifram

uocant)." [Stifel, _Arithmetica integra_, 1544, f. 1.]

[242] "Zifra, & Nulla uel figura Nihili." [Scheubel, 1545, p. 1 of ch. 1.]

_Nulla_ is also used by Italian writers. Thus Sfortunati (1545 ed., f. 4)

says: "et la decima nulla & e chiamata questa decima zero;" Cataldi (1602,

p. 1): "La prima, che e o, si chiama nulla, ouero zero, ouero niente." It

also found its way into the Dutch arithmetics, e.g. Raets (1576, 1580 ed.,

f. A_3): "Nullo dat ist niet;" Van der Schuere (1600, 1624 ed., f. 7);

Wilkens (1669 ed., p. 1). In Germany Johann Albert (Wittenberg, 1534) and

Rudolff (1526) both adopted the Italian _nulla_ and popularized it. (See

also Kuckuck, _Die Rechenkunst im sechzehnten Jahrhundert_, Berlin, 1874,

p. 7; Guenther, _Geschichte_, p. 316.)

[243] "La dixieme s'appelle chifre vulgairement: les vns l'appellant zero:

nous la pourrons appeller vn Rien." [Peletier, 1607 ed., p. 14.]

[244] It appears in the Polish arithmetic of K[=l]os (1538) as _cyfra_.

"The Ciphra 0 augmenteth places, but of himselfe signifieth not," Digges,

1579, p. 1. Hodder (10th ed., 1672, p. 2) uses only this word (cypher or

cipher), and the same is true of the first native American arithmetic,

written by Isaac Greenwood (1729, p. 1). Petrus de Dacia derives _cyfra_

from circumference. "Vocatur etiam cyfra, quasi circumfacta vel

circumferenda, quod idem est, quod circulus non habito respectu ad

centrum." [Loc. cit., p. 26.]

[246] Martin, _Origine de notre systeme de numeration ecrite_, note 149, p.

36 of reprint, spells [Greek: tsiphra] from Maximus Planudes, citing Wallis

as an authority. This is an error, for Wallis gives the correct form as

above.

Alexander von Humboldt, "Ueber die bei verschiedenen Voelkern ueblichen

Systeme von Zahlzeichen und ueber den Ursprung des Stellenwerthes in den

indischen Zahlen," Crelle's _Journal fuer reine und angewandte Mathematik_,

Vol. IV, 1829, called attention to the work [Greek: arithmoi Indikoi] of

the monk Neophytos, supposed to be of the fourteenth century. In this work

the forms [Greek: tzuphra] and [Greek: tzumphra] appear. See also Boeckh,

_De abaco Graecorum_, Berlin, 1841, and Tannery, "Le Scholie du moine

Neophytos," _Revue Archeologique_, 1885, pp. 99-102. Jordan, loc. cit.,

gives from twelfth and thirteenth century manuscripts the forms _cifra_,

_ciffre_, _chifras_, and _cifrus_. Du Cange, _Glossarium mediae et infimae

Latinitatis_, Paris, 1842, gives also _chilerae_. Dasypodius,

_Institutiones Mathematicae_, Strassburg, 1593-1596, adds the forms

_zyphra_ and _syphra_. Boissiere, _L'art d'arythmetique contenant toute

dimention, tres-singulier et commode, tant pour l'art militaire que autres

calculations_, Paris, 1554: "Puis y en a vn autre dict zero lequel ne

designe nulle quantite par soy, ains seulement les loges vuides."

[247] _Propagation_, pp. 27, 234, 442. Treutlein, "Das Rechnen im 16.

Jahrhundert," _Abhandlungen zur Geschichte der Mathematik_, Vol. I, p. 5,

favors the same view. It is combated by many writers, e.g. A. C. Burnell,

loc. cit., p. 59. Long before Woepcke, I. F. and G. I. Weidler, _De

characteribus numerorum vulgaribus et eorum aetatibus_, Wittenberg, 1727,

asserted the possibility of their introduction into Greece by Pythagoras or

one of his followers: "Potuerunt autem ex oriente, uel ex phoenicia, ad

graecos traduci, uel Pythagorae, uel eius discipulorum auxilio, cum aliquis

eo, proficiendi in literis causa, iter faceret, et hoc quoque inuentum

addisceret."

[248] E.g., they adopted the Greek numerals in use in Damascus and Syria,

and the Coptic in Egypt. Theophanes (758-818 A.D.), _Chronographia_,

Scriptores Historiae Byzantinae, Vol. XXXIX, Bonnae, 1839, p. 575, relates

that in 699 A.D. the caliph Wal[=i]d forbade the use of the Greek language

in the bookkeeping of the treasury of the caliphate, but permitted the use

of the Greek alphabetic numerals, since the Arabs had no convenient number

notation: [Greek: kai ekoluse graphesthai Hellenisti tous demosious ton

logothesion kodikas, all' Arabiois auta parasemainesthai, choris ton

psephon, epeide adunaton tei ekeinon glossei monada e duada e triada e okto

hemisu e tria graphesthai; dio kai heos semeron eisin sun autois notarioi

Christianoi.] The importance of this contemporaneous document was pointed

out by Martin, loc. cit. Karabacek, "Die Involutio im arabischen

Schriftwesen," Vol. CXXXV of _Sitzungsberichte d. phil.-hist. Classe d. k.

Akad. d. Wiss._, Vienna, 1896, p. 25, gives an Arabic date of 868 A.D. in

Greek letters.

Wittenberg, 1755, speaks of the "figura cifrarum Saracenicarum" as being

different from that of the "characterum Boethianorum," which are similar to

the "vulgar" or common numerals; see also Humboldt, loc. cit.

[254] Gerhardt mentions it in his _Entstehung_ etc., p. 8; Woepcke,

_Propagation_, states that these numerals were used not for calculation,

but very much as we use Roman numerals. These superposed dots are found

with both forms of numerals (_Propagation_, pp. 244-246).

[255] Gerhardt (_Etudes_, p. 9) from a manuscript in the Bibliotheque

Nationale. The numeral forms are [symbols], 20 being indicated by [symbol

with dot] and 200 by [symbol with 2 dots]. This scheme of zero dots was

also adopted by the Byzantine Greeks, for a manuscript of Planudes in the

Bibliotheque Nationale has numbers like [pi alpha with 4 dots] for

8,100,000,000. See Gerhardt, _Etudes_, p. 19. Pihan, _Expose_ etc., p. 208,

gives two forms, Asiatic and Maghrebian, of "Ghob[=a]r" numerals.

numerals.

forms, calling them _Indien_.

[271] Woepcke, "Introduction au calcul Gob[=a]r[=i] et Haw[=a][=i]," _Atti

dell' accademia pontificia dei nuovi Lincei_, Vol. XIX. The adjective

applied to the forms in 5 is _gob[=a]r[=i]_ and to those in 6 _indienne_.

This is the direct opposite of Woepcke's use of these adjectives in the

_Recherches sur l'histoire_ cited above, in which the ordinary Arabic forms

(like those in row 5) are called _indiens_.

These forms are usually written from right to left.

[272] J. G. Wilkinson, _The Manners and Customs of the Ancient Egyptians_,

revised by S. Birch, London, 1878, Vol. II, p. 493, plate XVI.

[273] There is an extensive literature on this "Boethius-Frage." The reader

who cares to go fully into it should consult the various volumes of the

_Jahrbuch ueber die Fortschritte der Mathematik_.

[274] This title was first applied to Roman emperors in posthumous coins of

Julius Caesar. Subsequently the emperors assumed it during their own

lifetimes, thus deifying themselves. See F. Gnecchi, _Monete romane_, 2d

ed., Milan, 1900, p. 299.

[275] This is the common spelling of the name, although the more correct

Latin form is Boetius. See Harper's _Dict. of Class. Lit. and Antiq._, New

York, 1897, Vol. I, p. 213. There is much uncertainty as to his life. A

good summary of the evidence is given in the last two editions of the

_Encyclopaedia Britannica_.

[276] His father, Flavius Manlius Boethius, was consul in 487.

[277] There is, however, no good historic evidence of this sojourn in

Athens.

[278] His arithmetic is dedicated to Symmachus: "Domino suo patricio

Symmacho Boetius." [Friedlein ed., p. 3.]

[279] It was while here that he wrote _De consolatione philosophiae_.

[280] It is sometimes given as 525.

[281] There was a medieval tradition that he was executed because of a work

on the Trinity.

[282] Hence the _Divus_ in his name.

[283] Thus Dante, speaking of his burial place in the monastery of St.

Pietro in Ciel d'Oro, at Pavia, says:

"The saintly soul, that shows

The world's deceitfulness, to all who hear him,

Is, with the sight of all the good that is,

Blest there. The limbs, whence it was driven, lie

Down in Cieldauro; and from martyrdom

And exile came it here."--_Paradiso_, Canto X.

[284] Not, however, in the mercantile schools. The arithmetic of Boethius

would have been about the last book to be thought of in such institutions.

While referred to by Baeda (672-735) and Hrabanus Maurus (c. 776-856), it

was only after Gerbert's time that the _Boetii de institutione arithmetica

libri duo_ was really a common work.

[285] Also spelled Cassiodorius.

[286] As a matter of fact, Boethius could not have translated any work by

Pythagoras on music, because there was no such work, but he did make the

theories of the Pythagoreans known. Neither did he translate Nicomachus,

although he embodied many of the ideas of the Greek writer in his own

arithmetic. Gibbon follows Cassiodorus in these statements in his _Decline

and Fall of the Roman Empire_, chap. xxxix. Martin pointed out with

positiveness the similarity of the first book of Boethius to the first five

books of Nicomachus. [_Les signes numeraux_ etc., reprint, p. 4.]

[287] The general idea goes back to Pythagoras, however.

[288] J. C. Scaliger in his _Poetice_ also said of him: "Boethii Severini

ingenium, eruditio, ars, sapientia facile provocat omnes auctores, sive

illi Graeci sint, sive Latini" [Heilbronner, _Hist. math. univ._, p. 387].

Libri, speaking of the time of Boethius, remarks: "Nous voyons du temps de

Theodoric, les lettres reprendre une nouvelle vie en Italie, les ecoles

florissantes et les savans honores. Et certes les ouvrages de Boece, de

Cassiodore, de Symmaque, surpassent de beaucoup toutes les productions du

siecle precedent." [_Histoire des mathematiques_, Vol. I, p. 78.]

[289] Carra de Vaux, _Avicenne_, Paris, 1900; Woepcke, _Sur

l'introduction_, etc.; Gerhardt, _Entstehung_ etc., p. 20. Avicenna is a

corruption from Ibn S[=i]n[=a], as pointed out by Wuestenfeld, _Geschichte

der arabischen Aerzte und Naturforscher_, Goettingen, 1840. His full name is

Ab[=u] `Al[=i] al-[H.]osein ibn S[=i]n[=a]. For notes on Avicenna's

arithmetic, see Woepcke, _Propagation_, p. 502.

"Seres etiam habitantesque sub ipso sole Indi, cum gemmis et margaritis

elephantes quoque inter munera trahentes nihil magis quam longinquitatem

viae imputabant." Horace shows his geographical knowledge by saying: "Not

those who drink of the deep Danube shall now break the Julian edicts; not

the Getae, not the Seres, nor the perfidious Persians, nor those born on

the river Tanais." [_Odes_, Bk. IV, Ode 15, 21-24.]

[320] "Qua virtutis moderationisque fama Indos etiam ac Scythas auditu modo

cognitos pellexit ad amicitiam suam populique Romani ultro per legatos

petendam." [Reinaud, loc. cit., p. 180.]

[321] Reinaud, loc. cit., p. 180.

Arma deus Caesar dites meditatur ad Indos

his ships to cut the gem-bearing seas."

[323] Heyd, loc. cit., Vol. I, p. 4.

[324] Reinaud, loc. cit., p. 393.

[325] The title page of Calandri (1491), for example, represents Pythagoras

with these numerals before him. [Smith, _Rara Arithmetica_, p. 46.] Isaacus

Vossius, _Observationes ad Pomponium Melam de situ orbis_, 1658, maintained

that the Arabs derived these numerals from the west. A learned dissertation

to this effect, but deriving them from the Romans instead of the Greeks,

was written by Ginanni in 1753 (_Dissertatio mathematica critica de

numeralium notarum minuscularum origine_, Venice, 1753). See also Mannert,

_De numerorum quos arabicos vocant vera origine Pythagorica_, Nuernberg,

1801. Even as late as 1827 Romagnosi (in his supplement to _Ricerche

storiche sull' India_ etc., by Robertson, Vol. II, p. 580, 1827) asserted

that Pythagoras originated them. [R. Bombelli, _L'antica numerazione

italica_, Rome, 1876, p. 59.] Gow (_Hist. of Greek Math._, p. 98) thinks

that Iamblichus must have known a similar system in order to have worked

out certain of his theorems, but this is an unwarranted deduction from the

passage given.

next taken up in a large way by Weidler, loc. cit., _De characteribus_

etc., 1727, and in _Spicilegium_ etc., 1755.

[335] The best edition of these works is that of G. Friedlein, _Anicii

Manlii Torquati Severini Boetii de institutione arithmetica libri duo, de

institutione musica libri quinque. Accedit geometria quae fertur

Boetii_.... Leipzig.... MDCCCLXVII.

[336] See also P. Tannery, "Notes sur la pseudo-geometrie de Boece," in

_Bibliotheca Mathematica_, Vol. I (3), p. 39. This is not the geometry in

two books in which are mentioned the numerals. There is a manuscript of

this pseudo-geometry of the ninth century, but the earliest one of the

other work is of the eleventh century (Tannery), unless the Vatican codex

is of the tenth century as Friedlein (p. 372) asserts.

[337] Friedlein feels that it is partly spurious, but he says: "Eorum

librorum, quos Boetius de geometria scripsisse dicitur, investigare veram

inscriptionem nihil aliud esset nisi operam et tempus perdere." [Preface,

p. v.] N. Bubnov in the Russian _Journal of the Ministry of Public

Instruction_, 1907, in an article of which a synopsis is given in the

_Jahrbuch ueber die Fortschritte der Mathematik_ for 1907, asserts that the

geometry was written in the eleventh century.

[338] The most noteworthy of these was for a long time Cantor

(_Geschichte_, Vol. I., 3d ed., pp. 587-588), who in his earlier days even

believed that Pythagoras had known them. Cantor says (_Die roemischen

Agrimensoren_, Leipzig, 1875, p. 130): "Uns also, wir wiederholen es, ist

die Geometrie des Boetius echt, dieselbe Schrift, welche er nach Euklid

bearbeitete, von welcher ein Codex bereits in Jahre 821 im Kloster

Reichenau vorhanden war, von welcher ein anderes Exemplar im Jahre 982 zu

Mantua in die Haende Gerbert's gelangte, von welcher mannigfache

Handschriften noch heute vorhanden sind." But against this opinion of the

antiquity of MSS. containing these numerals is the important statement of

P. Tannery, perhaps the most critical of modern historians of mathematics,

that none exists earlier than the eleventh century. See also J. L. Heiberg

in _Philologus, Zeitschrift f. d. klass. Altertum_, Vol. XLIII, p. 508.

Of Cantor's predecessors, Th. H. Martin was one of the most prominent, his

argument for authenticity appearing in the _Revue Archeologique_ for

1856-1857, and in his treatise _Les signes numeraux_ etc. See also M.

Chasles, "De la connaissance qu'ont eu les anciens d'une numeration

decimale ecrite qui fait usage de neuf chiffres prenant les valeurs de

position," _Comptes rendus_, Vol. VI, pp. 678-680; "Sur l'origine de notre

systeme de numeration," _Comptes rendus_, Vol. VIII, pp. 72-81; and note

nouveau systeme de numeration," in his work _Apercu historique sur

l'origine et le developpement des methodes en geometrie_, of which the

first edition appeared in 1837.

[341] In a Plimpton manuscript of the arithmetic of Boethius of the

thirteenth century, for example, the Roman numerals are all replaced by the

Arabic, and the same is true in the first printed edition of the book. (See

Smith's _Rara Arithmetica_, pp. 434, 25-27.) D. E. Smith also copied from a

manuscript of the arithmetic in the Laurentian library at Florence, of

1370, the following forms, [Forged numerals

[342] Halliwell, in his _Rara Mathematica, _p. 107, states that the

disputed passage is not in a manuscript belonging to Mr. Ames, nor in one

at Trinity College. See also Woepcke, in _Propagation_, pp. 37 and 42. It

was the evident corruption of the texts in such editions of Boethius as

those of Venice, 1499, Basel, 1546 and 1570, that led Woepcke to publish

his work _Sur l'introduction de l'arithmetique indienne en Occident_.

[343] They are found in none of the very ancient manuscripts, as, for

example, in the ninth-century (?) codex in the Laurentian library which one

of the authors has examined. It should be said, however, that the disputed

passage was written after the arithmetic, for it contains a reference to

that work. See the Friedlein ed., p. 397.

[347] _De ratione abaci._ In this he describes "quandam formulam, quam ob

honorem sui praeceptoris mensam Pythagoream nominabant ... a posterioribus

appellabatur abacus." This, as pictured in the text, is the common Gerbert

abacus. In the edition in Migne's _Patrologia Latina_, Vol. LXIII, an

ordinary multiplication table (sometimes called Pythagorean abacus) is

given in the illustration.

[349] C. Henry, "Sur l'origine de quelques notations mathematiques," _Revue

Archeologique_, 1879, derives these from the initial letters used as

abbreviations for the names of the numerals, a theory that finds few

supporters.

[350] E.g., it appears in Schonerus, _Algorithmus Demonstratus_, Nuernberg,

1534, f. A4. In England it appeared in the earliest English arithmetical

manuscript known, _The Crafte of Nombrynge_: "¶ fforthermore ye most

vndirstonde that in this craft ben vsid teen figurys, as here bene writen

for ensampul, [Numerals] ... in the quych we vse teen figurys of Inde.

Bubnov, loc. cit., pp. 376-381; Nagl, _Gerbert und die Rechenkunst des 10.

[435] Richer tells of the visit to Aurillac by Borel, a Spanish nobleman,

just as Gerbert was entering into young manhood. He relates how

affectionately the abbot received him, asking if there were men in Spain

well versed in the arts. Upon Borel's reply in the affirmative, the abbot

asked that one of his young men might accompany him upon his return, that

he might carry on his studies there.

[436] Vicus Ausona. Hatto also appears as Atton and Hatton.

[437] This is all that we know of his sojourn in Spain, and this comes from

his pupil Richer. The stories told by Adhemar of Chabanois, an apparently

ignorant and certainly untrustworthy contemporary, of his going to Cordova,

are unsupported. (See e.g. Picavet, p. 34.) Nevertheless this testimony is

still accepted: K. von Raumer, for example (_Geschichte der Paedagogik_, 6th

ed., 1890, Vol. I, p. 6), says "Mathematik studierte man im Mittelalter bei

den Arabern in Spanien. Zu ihnen gieng Gerbert, nachmaliger Pabst Sylvester

II."

[438] Thus in a letter to Aldaberon he says: "Quos post repperimus

speretis, id est VIII volumina Boeti de astrologia, praeclarissima quoque

figurarum geometriae, aliaque non minus admiranda" (Epist. 8). Also in a

letter to Rainard (Epist. 130), he says: "Ex tuis sumptibus fac ut michi

scribantur M. Manlius (Manilius in one MS.) de astrologia."

[Quoted in Bombelli, _L'antica numerazione Italica_, Rome, 1876, p. 41 n.]

[444] He writes from Rheims in 984 to one Lupitus, in Barcelona, saying:

"Itaque librum de astrologia translatum a te michi petenti dirige,"

presumably referring to some Arabic treatise. [Epist. no. 24 of the Havet

collection, p. 19.]

[445] See Bubnov, loc. cit., p. x.

[446] Olleris, loc. cit., p. 361, l. 15, for Bernelinus; and Bubnov, loc.

(_Abhandlungen zur Geschichte der Mathematik_, Vol. V, pp. 85-133), p. 97.

[448] Weissenborn, loc. cit., p. 239. When Olleris (_Oeuvres de Gerbert_,

Paris, 1867, p. cci) says, "C'est a lui et non point aux Arabes, que

l'Europe doit son systeme et ses signes de numeration," he exaggerates,

since the evidence is all against his knowing the place value. Friedlein

emphasizes this in the _Zeitschrift fuer Mathematik und Physik_, Vol. XII

(1867), _Literaturzeitung_, p. 70: "Fuer das _System_ unserer Numeration ist

die _Null_ das wesentlichste Merkmal, und diese kannte Gerbert nicht. Er

selbst schrieb alle Zahlen mit den roemischen Zahlzeichen und man kann ihm

also nicht verdanken, was er selbst nicht kannte."

[449] E.g., Chasles, Buedinger, Gerhardt, and Richer. So Martin (_Recherches

nouvelles_ etc.) believes that Gerbert received them from Boethius or his

followers. See Woepcke, _Propagation_, p. 41.

[450] Buedinger, loc. cit., p. 10. Nevertheless, in Gerbert's time one

Al-Man[s.][=u]r, governing Spain under the name of Hish[=a]m (976-1002),

called from the Orient Al-Be[.g][=a]n[=i] to teach his son, so that

scholars were recognized. [Picavet, p. 36.]

[453] These letters, of the period 983-997, were edited by Havet, loc.

cit., and, less completely, by Olleris, loc. cit. Those touching

mathematical topics were edited by Bubnov, loc. cit., pp. 98-106.

[454] He published it in the _Monumenta Germaniae historica_, "Scriptores,"

Vol. III, and at least three other editions have since appeared, viz. those

by Guadet in 1845, by Poinsignon in 1855, and by Waitz in 1877.

[456] In epistle 17 (Havet collection) he speaks of the "De multiplicatione

et divisione numerorum libellum a Joseph Ispano editum abbas Warnerius" (a

person otherwise unknown). In epistle 25 he says: "De multiplicatione et

divisione numerorum, Joseph Sapiens sententias quasdam edidit."

Josephs very carefully, but could find nothing save that "Josephus Hispanus

seu Josephus sapiens videtur aut Maurus fuisse aut alius quis in Hispania."

[458] P. Ewald, _Mittheilungen, Neues Archiv d. Gesellschaft fuer aeltere

[459] It is entitled _Constantino suo Gerbertus scolasticus_, because it

was addressed to Constantine, a monk of the Abbey of Fleury. The text of

the letter to Constantine, preceding the treatise on the Abacus, is given

in the _Comptes rendus_, Vol. XVI (1843), p. 295. This book seems to have

been written c. 980 A.D. [Bubnov, loc. cit., p. 6.]

[462] Friedlein thought it spurious. See _Zeitschrift fuer Mathematik und

Physik_, Vol. XII (1867), Hist.-lit. suppl., p. 74. It was discovered in

the library of the Benedictine monastry of St. Peter, at Salzburg, and was

published by Peter Bernhard Pez in 1721. Doubt was first cast upon it in

the Olleris edition (_Oeuvres de Gerbert_). See Weissenborn, _Gerbert_, pp.

2, 6, 168, and Picavet, p. 81. Hock, Cantor, and Th. Martin place the

composition of the work at c. 996 when Gerbert was in Germany, while

Olleris and Picavet refer it to the period when he was at Rheims.

[463] Picavet, loc. cit., p. 182.

[464] Who wrote after Gerbert became pope, for he uses, in his preface, the

words, "a domino pape Gerberto." He was quite certainly not later than the

eleventh century; we do not have exact information about the time in which

he lived.

[468] Writers on numismatics are quite uncertain as to their use. See F.

Gnecchi, _Monete Romane_, 2d ed., Milan, 1900, cap. XXXVII. For pictures of

old Greek tesserae of Sarmatia, see S. Ambrosoli, _Monete Greche_, Milan,

1899, p. 202.

[469] Thus Tzwivel's arithmetic of 1507, fol. 2, v., speaks of the ten

figures as "characteres sive numerorum apices a diuo Seuerino Boetio."

[470] Weissenborn uses _sipos_ for 0. It is not given by Bernelinus, and

appears in Radulph of Laon, in the twelfth century. See Guenther's

_Geschichte_, p. 98, n.; Weissenborn, p. 11; Pihan, _Expose_ etc., pp.

xvi-xxii.

In Friedlein's _Boetius_, p. 396, the plate shows that all of the six

important manuscripts from which the illustrations are taken contain the

symbol, while four out of five which give the words use the word _sipos_

for 0. The names appear in a twelfth-century anonymous manuscript in the

Vatican, in a passage beginning

Ordine primigeno sibi nomen possidet igin.

Andras ecce locum mox uendicat ipse secundum

Ormis post numeros incompositus sibi primus.

[Boncompagni _Buttetino_, XV, p. 132.] Turchill (twelfth century) gives the

names Igin, andras, hormis, arbas, quimas, caletis, zenis, temenias,

celentis, saying: "Has autem figuras, ut donnus [dominus] Gvillelmus Rx

testatur, a pytagoricis habemus, nomina uero ab arabibus." (Who the William

R. was is not known. Boncompagni _Bulletino_ XV, p. 136.) Radulph of Laon

(d. 1131) asserted that they were Chaldean (_Propagation_, p. 48 n.). A

discussion of the whole question is also given in E. C. Bayley, loc. cit.

Huet, writing in 1679, asserted that they were of Semitic origin, as did

Nesselmann in spite of his despair over ormis, calctis, and celentis; see

Woepcke, _Propagation_, p. 48. The names were used as late as the fifteenth

century, without the zero, but with the superscript dot for 10's, two dots

for 100's, etc., as among the early Arabs. Gerhardt mentions having seen a

fourteenth or fifteenth century manuscript in the Bibliotheca Amploniana

with the names "Ingnin, andras, armis, arbas, quinas, calctis, zencis,

zemenias, zcelentis," and the statement "Si unum punctum super ingnin

ponitur, X significat.... Si duo puncta super ... figuras superponunter,

fiet decuplim illius quod cum uno puncto significabatur," in

numero notas omnem numerum significantes." [Bubnov, loc. cit., p. 381.]

[473] "Il y a dix Characteres, autrement Figures, Notes, ou Elements."

[Peletier, edition of 1607, p. 13.] "Numerorum notas alij figuras, alij

signa, alij characteres uocant." [Glareanus, 1545 edition, f. 9, r.] "Per

figuras (quas zyphras uocant) assignationem, quales sunt hae notulae, 1. 2.

3. 4...." [Noviomagus, _De Numeris Libri II_, cap. vi.] Gemma Frisius also

uses _elementa_ and Cardan uses _literae_. In the first arithmetic by an

American (Greenwood, 1729) the author speaks of "a few Arabian _Charecters_

or Numeral Figures, called _Digits_" (p. 1), and as late as 1790, in the

third edition of J. J. Blassiere's arithmetic (1st ed. 1769), the name

_characters_ is still in use, both for "de Latynsche en de Arabische" (p.

4), as is also the term "Cyfferletters" (p. 6, n.). _Ziffer_, the modern

German form of cipher, was commonly used to designate any of the nine

figures, as by Boeschenstein and Riese, although others, like Koebel, used

it only for the zero. So _zifre_ appears in the arithmetic by Borgo, 1550

ed. In a Munich codex of the twelfth century, attributed to Gerland, they

are called _characters_ only: "Usque ad VIIII. enim porrigitur omnis

numerus et qui supercrescit eisdem designator Karacteribus." [Boncompagni

_Bulletino_, Vol. X. p. 607.]

[474] The title of his work is _Prologus N. Ocreati in Helceph_ (Arabic

_al-qeif_, investigation or memoir) _ad Adelardum Batensem magistrum suum_.

The work was made known by C. Henry, in the _Zeitschrift fuer Mathematik und

Physik_, Vol. XXV, p. 129, and in the _Abhandlungen zur Geschichte der

Mathematik_, Vol. III; Weissenborn, _Gerbert_, p. 188.

[475] The zero is indicated by a vacant column.

[476] Leo Jordan, loc. cit., p. 170. "Chifre en augorisme" is the

expression used, while a century later "giffre en argorisme" and "cyffres

d'augorisme" are similarly used.

[500] John is said to have died in 1157.

in full in the second part of Boncompagni's _Trattati d'aritmetica_.

[502] Possibly, indeed, the meaning of "libro alghoarismi" is not "to

Al-Khow[=a]razm[=i]'s book," but "to a book of algorism." John of Luna says

of it: "Hoc idem est illud etiam quod ... alcorismus dicere videtur."

as referring to two different systems, but the expression may very well

mean algorism as performed upon the Pythagorean arcs (or table).

[533] "Book of the Abacus," this term then being used, and long afterwards

in Italy, to mean merely the arithmetic of computation.

[534] "Incipit liber Abaci a Leonardo filio Bonacci compositus anno 1202 et

first printed by Boncompagni in 1857.

[536] On the commercial activity of the period, it is known that bills of

exchange passed between Messina and Constantinople in 1161, and that a bank

was founded at Venice in 1170, the Bank of San Marco being established in

the following year. The activity of Pisa was very manifest at this time.

[545] Curtze, loc. cit., found some forty-five copies of the _Algorismus_

in three libraries of Munich, Venice, and Erfurt (Amploniana). Examination

of two manuscripts from the Plimpton collection and the Columbia library

shows such marked divergence from each other and from the text published by

Curtze that the conclusion seems legitimate that these were students'

lecture notes. The shorthand character of the writing further confirms this

view, as it shows that they were written largely for the personal use of

the writers.

[546] "Quidam philosophus edidit nomine Algus, unde et Algorismus

nuncupatur." [Curtze, loc. cit., p. 1.]

[547] "Sinistrorsum autera scribimus in hac arte more arabico sive iudaico,

books, was printed by Caxton in 1480.

[554] Trevisa's translation, Higden having written in Latin.

[555] An illustration of this feeling is seen in the writings of Prosdocimo

de' Beldomandi (b. c. 1370-1380, d. 1428): "Inveni in quam pluribus libris

algorismi nuncupatis mores circa numeros operandi satis varios atque

diversos, qui licet boni existerent atque veri erant, tamen fastidiosi, tum

propter ipsarum regularum multitudinem, tum propter earum deleationes, tum

etiam propter ipsarum operationum probationes, utrum si bone fuerint vel

ne. Erant et etiam isti modi interim fastidiosi, quod si in aliquo calculo

astroloico error contigisset, calculatorem operationem suam a capite

incipere oportebat, dato quod error suus adhuc satis propinquus existeret;

et hoc propter figuras in sua operatione deletas. Indigebat etiam

calculator semper aliquo lapide vel sibi conformi, super quo scribere atque

faciliter delere posset figuras cum quibus operabatur in calculo suo. Et

quia haec omnia satis fastidiosa atque laboriosa mihi visa sunt, disposui

libellum edere in quo omnia ista abicerentur: qui etiam algorismus sive

liber de numeris denominari poterit. Scias tamen quod in hoc libello ponere

non intendo nisi ea quae ad calculum necessaria sunt, alia quae in aliis

[582] From a manuscript, Add. Manuscript 27,589, British Museum, 1360 A.D.

The work is a computus in which the date 1360 appears, assigned in the

British Museum catalogue to the thirteenth century.

[583] From the copy of Sacrabosco's _Algorismus_ in Mr. Plimpton's library.

Date c. 1442. See Smith, _Rara Arithmetica_, p. 450.

[585] Ibid., pp. 469-470.

[586] Ibid., pp. 477-478.

[587] The i is used for "one" in the Treviso arithmetic (1478), Clichtoveus

(c. 1507 ed., where both i and j are so used), Chiarini (1481), Sacrobosco

(1488 ed.), and Tzwivel (1507 ed., where jj and jz are used for 11 and 12).

This was not universal, however, for the _Algorithmus linealis_ of c. 1488

has a special type for 1. In a student's notebook of lectures taken at the

University of Wuerzburg in 1660, in Mr. Plimpton's library, the ones are all

in the form of i.

[588] Thus the date [Numerals 1580], for 1580, appears in a MS. in the

Laurentian library at Florence. The second and the following five

characters are taken from Cappelli's _Dizionario_, p. 380, and are from

manuscripts of the twelfth, thirteenth, fourteenth, sixteenth, seventeenth,

and eighteenth centuries, respectively.

[589] E.g. Chiarini's work of 1481; Clichtoveus (c. 1507).

[590] The first is from an algorismus of the thirteenth century, in the

Hannover Library. [See Gerhardt, "Ueber die Entstehung und Ausbreitung des

dekadischen Zahlensystems," loc. cit., p. 28.] The second character is from

a French algorismus, c. 1275. [Boncompagni _Bulletino_, Vol. XV, p. 51.]

The third and the following sixteen characters are given by Cappelli, loc.

cit., and are from manuscripts of the twelfth (1), thirteenth (2),

Cappelli, loc. cit.

[603] French algorismus, c. 1275, for the first of these forms. Cappelli,

thirteenth, fourteenth, fifteenth (3), and seventeenth centuries,

numerorum notis.... Sunt & aliae quaedam notae, quibus Chaldaei & Astrologii

quemlibet numerum artificiose & argute describunt, scitu periucundae, quas

nobis communicauit Rodolphus Paludanus Nouiomagus."
