Also many good and pregnant Englishe wittes, of young Gentlemen, and of

other, who neuer intend to meddle with the profound search and Studie of

Philosophie (in the _Vniuersities_ to be learned) may neuerthelesse,

now, with more ease and libertie, haue good occasion, vertuously to

occupie the sharpnesse of their wittes: where, els (perchance)

otherwise, they would in fond exercises, spend (or rather leese) their

time: neither seruing God: nor furdering the Weale, common or priuate.

[5.]

And great Comfort, with good hope, may the _Vniuersities_ haue, by

reason of this _Englishe_ +Geometrie, and Mathematicall Præface+, that

they (hereafter) shall be the more regarded, esteemed, and resorted

vnto. For, when it shall be knowen and reported, that of the

_Mathematicall Sciences_ onely, such great Commodities are ensuing (as I

haue specified): and that in dede, some of you vnlatined Studentes, can

be good witnesse, of such rare fruite by you enioyed (thereby): as

either, before this, was not heard of: or els, not so fully credited:

“Well, may all men coniecture, that farre greater ayde, and better

furniture, to winne to the Perfection of all Philosophie,

[Vniuersities.]

may in the Vniuersities be had: being the Storehouses & Threasory of all

Sciences,

[☞]

and all Artes, necessary for the best, and most noble State of Common

Wealthes.”

[6.]

Besides this, how many a Common Artificer, is there, in these Realmes of

England and Ireland, that dealeth with Numbers, Rule, & Cumpasse: Who,

with their owne Skill and experience, already had, will be hable (by

these good helpes and informations) to finde out, and deuise, new

workes, straunge Engines, and Instrumentes: for sundry purposes in the

Common Wealth? or for priuate pleasure? and for the better maintayning

of their owne estate? I will not (therefore) fight against myne owne

shadowe. For, no man (I am sure) will open his mouth against this

Enterprise. No mã (I say) who either hath Charitie toward his brother

(and would be glad of his furtherance in vertuous knowledge): or that

hath any care & zeale for the bettering of the Cõmon state of this

Realme. Neither any, that make accompt, what the wiser sort of men (Sage

and Stayed) do thinke of them. To none (therefore) will I make any

_Apologie,_ for a vertuous acte doing: and for cõmending, or setting

forth, Profitable Artes to English men, in the English toung. “But, vnto

God our Creator, let vs all be thankefull: for that, +_As he, of his

Goodnes, by his Powre, and in his wisedome,

[☞]

hath Created all thynges, in Number, Waight, and Measure_+: So, to vs,

of hys great Mercy, he hath reuealed Meanes, whereby, to atteyne the

sufficient and necessary knowledge of the foresayd hys three principall

Instrumentes: Which Meanes, I haue abundantly proued vnto you, to be the

_Sciences_ and _Artes Mathematicall_.”

And though I haue ben pinched with straightnes of tyme: that, no way,

I could so pen downe the matter (in my Mynde) as I determined: hopyng of

conuenient laysure: Yet. if vertuous zeale, and honest Intent prouoke

and bryng you to the readyng and examinyng of this Compendious treatise,

I do not doute, but, as the veritie therof (accordyng to our purpose)

will be euident vnto you: So the pith and force therof, will persuade

you: and the wonderfull frute therof, highly pleasure you. And that you

may the easier perceiue, and better remember, the principall pointes,

whereof my Preface treateth,

[The Ground platt of this Præface in a Table.]

I will giue you the +Groundplatt+ of my whole discourse, in a Table

annexed: from the first to the last, somewhat Methodically contriued.

If Hast, hath caused my poore pen, any where, to stumble: You will,

(I am sure) in part of recompence, (for my earnest and sincere

good will to pleasure you), Consider the rockish huge

mountaines, and the perilous vnbeaten wayes, which

(both night and day, for the while) it hath

toyled and labored through, to bryng you

this good Newes, and Comfortable

profe, of Vertues frute.

So, I Commit you vnto Gods Mercyfull direction, for the rest:

hartely besechyng hym, to prosper your Studyes, and

honest Intentes: to his Glory, & the Commodity

of our Countrey. _Amen_.

Errors and Anomalies:

Unless otherwise noted, spelling and punctuation are unchanged.

Errors are listed below, with the original form, if changed, shown in

[brackets]. Unusual words include “fatch” (probably used as a variant

of “fetch”) and the mathematical terms “sexagene” and “sexagesme”.

Additional Notes:

The Greek letter η (eta) was consistently printed as if it were the

ou-ligature ȣ.

The Latin “-que” was written as an abbreviation resembling “-q´;”.

It is shown here as [que].

Mathematical symbols seen in the section accompanying the diagrams

could not be reproduced. The following substitutions were made:

--The curly “P” used for “Pounds” is shown as {P}.

--The “potestas” symbol, used to represent “x” (the unknown),

is shown as {x}.

--All roots were expressed as the “root” sign √ combined with

symbols for the power of 2 (doubled for power of 4, or fourth root)

and 3. They are shown as ²√ ³√ ⁴√.

Euclid:

The following Propositions were identified by number.

6.12: (How) to find a fourth (line) proportional to three given straight

lines.

11.34: In equal parallelepipedal solids the bases are reciprocally

proportional to the heights; and those parallelepipedal solids in which

the bases are reciprocally proportional to the heights are equal.

11.36: If three straight lines are proportional, then the

parallelepipedal solid formed out of the three equals the

parallelepipedal solid on the mean which is equilateral, but equiangular

with the aforesaid solid.

12.1: Similar polygons inscribed in circles are to one another as the

squares on their diameters.

12.2: Circles are to one another as the squares on their diameters.

12.18 (“last”): Spheres are to one another in triplicate ratio of their

respective diameters.
