[f] Cæsar's speech for Decius the Samnite, and all his other productions (except the Commentaries), are totally lost.
[g] This speech of Brutus is also lost with his other works. Cicero says, he heard him plead the cause of Dejotarus with great elegance, and a flow of harmonious periods. _Causam Dejotari, fidelissimi atque optimi regis, ornatissimè et copiosissimè a Bruto me audisse defensam. De Claris Orat._ s. 21. He tells us in another place, that Cæsar observed of Brutus, that whatever he desired, he desired with ardour; and therefore, in the cause of Dejotarus, he exerted himself with warmth, with vehemence, and great freedom of language. _Quidquid vult, valdè vult; ideoque, cum pro rege Dejotaro dixerit, valdè vehementer eum visum, et liberè dicere. Ad Attic._ lib. xiv. ep. 1. The same Dejotarus was afterwards defended by Cicero before Cæsar himself. See the Oration _pro Rege Dejotaro_.
[h] See what is said of Asinius Pollio, s. xii. note [e].
[i] Pliny the younger has the same metaphorical allusions, which we here find in the Dialogue. Speaking of the difference between the oratorial and historical style; the latter, he says, may be content with the bones, the muscles, and the nerves; the former must have the prominence of the flesh, the brawny vigour, and the flowing mane. _Habent quidem oratio et historia multa communia, sed plura diversa in his ipsis, quæ communia videntur. Narrat sane illa, narrat hæc, sed aliter. Huic pleraque humilia, et sordida, et ex medio petita: illi omnia recondita, splendida, excelsa conveniunt. Hanc sæpius ossa, musculi, nervi; illam tori quidam, et quasi jubæ decent._ Lib. v. ep. 8.
[k] Messala Corvinus has been often mentioned. See for him s. xii. note [e].
[a] The words _sententia_ and _sensus_ were technical terms with the critics of antiquity. Quintilian gives the distinct meaning of each, with his usual precision. According to the established usage, the word _sensus_ signified our ideas or conceptions, as they rise in the mind: by _sententia_ was intended, a proposition, in the close of a period, so expressed, as to dart a sudden brilliancy, for that reason called _lumen orationis_. He says, these artificial ornaments, which the ancients used but sparingly, were the constant practice of the modern orators. _Consuetudo jam tenuit, ut mente concepta_, SENSUS _vocaremus; lumina autem, præcipuèque in clausulis posita_, SENTENTIAS. _Quæ minus crebra apud antiquos, nostris temporibus modo carent._ Lib. viii. cap. 5. These luminous sentences, Quintilian says, may be called the eyes of an oration; but eyes are not to be placed in every part, lest the other members should lose their function. _Ego vero hæc lumina orationis velut oculos quosdam esse eloquentiæ credo: sed neque oculos esse toto corpore velim, ne cætera membra suum officium perdant._ Lib. viii, cap. 5. As Cowley says,
