23, just as he uses _tyrannus_ (_De Rep._ III. 45), and _anapaestus_ (_T.D._ III. 57) Might we not read _philosophis_, in the dative, which only requires the alteration of a single letter from the MSS. reading? The meaning would then be "to write _for_ philosophers," which would agree with my emendation _cum_ for _quo_ above. _Philosophice_ would be a tempting alteration, but that the word φιλοσοφικος is not Greek, nor do _philosophicus_, _philosophice_ occur till very late Latin times. _Si modo id consecuti sumus_: cf. _Brut._ 316. §9. _Sunt ista_: = εστι ταυτα, so often, e.g. _Lael._ 6. Some edd. have _sint_, which is unlikely to be right. _Nos in nostra_: Augustine (_De Civ. Dei_ VI. 2) quotes this with the reading _reduxerunt_ for _deduxerunt_, which is taken by Baiter and by Halm; who quotes with approval Durand's remark, "_deducimus honoris causa sed errantes reducimus humanitatis_." The words, however, are almost convertible; see _Cat. Mai._ 63. In _Lael._ 12, _Brut._ 86, we have _reducere_, where Durand's rule requires _deducere_, on the other hand cf. _Ad Herennium_ IV. 64, _hospites domum deducere. Aetatem patriae_ etc., August. (_De Civ. Dei_ VI. 3) describes Varro's "_Libri Antiquitatum_" (referred to in 8), in which most of the subjects here mentioned were treated of. _Descriptiones temporum_: lists of dates, so χρονοι is technically used for dates, Thuc. V. 20, etc. _Tu sacerdotum_: after this Lamb. inserts _munera_ to keep the balance of the clauses. Cic. however is quite as fond of variety as of formal accuracy. _Domesticam--bellicam_: opposed like _domi bellique_, cf. _Brut._ 49, _De Off._ I. 74. Augustine's reading _publicam_ shows him to have been quoting from memory. _Sedem_: so the best MSS. of Aug., some edd. here give _sedium_. The argument for _sedem_ is the awkwardness of making the three genitives, _sedium_, _regionum_, _locorum_, dependent on the accusatives, _nomina_, _genera_, _officia_, _causas_. Cic. is fond of using _sedes_, _locus_, _regio_ together, see _Pro Murena_, 85, _Pro Cluentio_, 171, quoted by Goer. _Omnium divinarum humanarumque rerum_: from the frequent references of Aug. it appears that the "_Libri Antiquitatum_" were divided into two parts, one treating of _res humanae_, the other of _res divinae_ (_De Civ. Dei_, IV. 1, 27, VI. 3). _Et litteris luminis_: for _luminis_, cf. _T.D._ I. 5. _Et verbis_: Manut. reads _rebus_ from 26. Varro's researches into the Latin tongue are meant. _Multis locis incohasti_: Varro's book "_De Philosophia_" had apparently not yet been written.
