1312. The verb #nāscor# and participles of origin take an ablative to
denote parentage or rank in life.
Such participles are: #nātus#, #prōgnātus#, and #ortus#; in poetry and
late prose, also #crētus#, #ēditus#, #generātus#, #genitus#, #satus#,
and #oriundus#: as, (_a._) #Rōmulus deō prōgnātus#, L. 1, 40, 3,
_Romulus, sprung from a god_. #dīs genite#, V. 9, 642, _thou sired of
gods_. Of a parent, #ex# is sometimes used: as #ex mē hic nātus nōn
est#, T. _Ad._ 40, _he’s not my son_; and of remoter ancestors, #ab#.
(_b._) #locō nātus honestō#, 5, 45, 2, _respectably descended_. #summō
locō nātus#, 5, 25, 1, _of high birth_, #familiā antīquissimā nātum#, 7,
32, 4, _a member of an old family_. Rarely with #dē#: as, #quō dē genere
gnātust Philocratēs?# Pl. _Cap._ 277, _what is the parentage of
Philocrates?_
1313. The ablative with an attribute, attached to a substantive,
sometimes denotes stuff or material: as, #aere cavō clipeum#, V. 3, 286,
_a targe of hallow bronze_. #perennī fronde corōnam#, Lucr. 1, 118,
_a crown of amaranthine leaf_. #solidōque adamante columnae#, V. 6, 552,
_and pillars of the solid adamant_. This construction borders closely on
the ablative of quality (1375). Rarely without an attribute: as, #pīctās
abiete puppīs#, V. 5, 663, _painted sterns of fir_.
1314. A substantive denoting stuff or material is generally put in the
ablative with #dē# or #ex#; thus,
(_a._) Directly with a substantive: #pōcula ex aurō#, _V._ 4, 62, _cups
of gold_. (_b._) Oftener with an auxiliary verb or participle: #sīgnum
erat hoc Cupīdinis ē marmore#, _V._ 4, 5, _this statue of Cupid was made
of marble_. #scūtīs ex cortice factīs#, 2, 33, 2, _with long shields
made out of bark_. #ex ūnā gemmā pergrandī trūlla excavāta#, _V._ 4, 62,
_a ladle scooped out of a single enormous semi-precious stone_.
1315. The ablative with forms of #faciō# and #sum# denotes that with
which or to which something is done: as, #quid hōc homine faciās?#
_Sest._ 29, _what can you do with such a fellow?_ #quid mē fīet?# T.
_Andr._ 709, _what will become of me?_ But often the dative (1205): as,
#quid tibī̆ faciam?# _Att._ 7, 3, 2, _what shall I do to you?_ Or the
ablative with #dē#: as, #dē frātre quid fīet?# T. _Ad._ 996, _as to my
brother, what will come to pass?_
