45-3.

Of the minor works on grammar, some at least were prior to the _De
Lingua Latina_: Cic. _Ac._ i. 9, 'Plurimum poetis nostris omninoque
Latinis et litteris luminis et verbis attulisti.' The titles known
are, _De sermone Latino_, _De origine linguae Latinae_, _De
similitudine verborum_, _De utilitate sermonis_, _De antiquitate
litterarum_, +Peri charakteron+.

3. _Roman History and Antiquities._ Varro's great work in this
department was the _Antiquitates rerum divinarum humanarumque_, in
forty-one Books. The arrangement, according to Augustine _De Civ.
Dei_, vi. 3, was as follows: (_a_) i.-xxv. _res humanae_; i.
introductory, ii.-vii. history of Rome down to its capture by the
Gauls, viii.-xiii. geography of Italy, xiv.-xix. Roman Calendar, with
dates of the chief historical events, xx.-xxv. Roman institutions, (_b_)
xxvi.-xli. _res divinae_; the persons who sacrifice, the places, the
times, the rites, and the gods were discussed in three Books each,
xxvi. being introductory. The second part, at least, was addressed to
Caesar as _pontifex maximus_. As it is mentioned by Cic. _Ac._ i. 9,
it must have been published before B.C. 45.

Minor works under this head were _Annales_, _Res urbanae_, _De gente
populi Romani_, _De vita populi Romani_, _De familiis Troianis_,
_Tribuum Liber_; _Aetia_ (+aitia+), explaining Roman usages, in the
form of a catechism; +Eisagogikos+ to Pompey on the duties of a
consul (B.C. 71), Gell. xiv. 7, 1; _De Pompeio_, _Legationum Libri_,
_De sua vita_.

4. _Geography._-(_a_) _Ephemeris navalis_, addressed to Pompey before
his departure for Spain about B.C. 77, a weather almanack for sailors;
_Ephemeris rustica_ or _agrestis_, for farmers. (_b_) _Libri navales_,
perhaps identical with the above, (_c_) _De ora maritima_.

5. _Law._--_De iure civili_ in fifteen Books.

6. _Rhetoric._--_Rhetorica_.

7. _Philosophy._-_De Forma Philosophiae_, _De Philosophia_.

8. _Mathematics_, etc.-_De mensuris_, _Mensuralia_, _De principiis
numerorum_, _Libri numerorum_, _De geometria_, _De astrologia_.

9. _Disciplinae_ in nine Books, forming a complete course of education
in the liberal arts.

10. _History of Literature and the Drama._--_De poetis_, _De
poematis_, _De lectionibus_, _De bibliothecis_, _De proprietate
scriptorum_, _De personis_, _De descriptionibus_, _De actis scenicis_,
_De scenicis actionibus_, _De originibus scenicis_, _Quaestiones
Plautinae_. In the _Hebdomades_ or _Ima
