Agroecius (fifth century), whose ‘disciplina’ is praised by Sidonius,[390] wrote a book on orthography,[391] which was intended to supplement a work on the same subject by Flavius Caper. And we hear of Dositheus’s _Chrestomathia_ or collection of passages from literature, intended for Greek students and written in both languages,[392] as a common text-book of the later Empire. Jerome mentions Sinnius Capito as an authority on antiquities who was still read in his day,[393] and therefore, considering the universality of the rhetorical tradition, probably used in the schools of Gaul. Some of his fragments may be taken as typical of the scope and character of the grammarian’s teaching. ‘Docet (Sin. Capit.) “pluria” Latinum esse, “plura” barbarum. Pluria sive plura absolutum esse et simplex, non comparativum.’[394] A solecism is defined as ‘impar atque inconveniens compositura partium orationis’. He does not neglect derivation: ‘pacem a pactione condicionum putat dictam Sinnius Capito’,[395] and in his philology a place is given to phonetics. ‘De syllabis, “f” praeponitur liquidis, nulla alia de semivocalibus; nam praeponitur liquidis duabus sola “f”; praeponitur “l” litterae, si dicas Flavius ... est libellus de syllabis, legite illum ... Sinni est liber Capitonis.’[396] Grammar, in the narrow sense, was naturally part of the grammarian’s work. ‘_Nec_ coniunctionem grammatici fere dicunt esse disiunctivam, ut “nec legit nec scribit”, cum si diligentius inspiciatur, ut fecit Sinnius Capito, intelligi possit eam positam esse ab antiquis pro _non_ ut et in XII est....’[397] His remarks on the verse of Lucilius,[398] ‘nequam aurum est’, &c., are an example of the ordinary exposition so plentifully illustrated in Servius, handed down from one generation of grammatici to another. His opinion is quoted also on historical questions: ‘Sardi venales (_alius alio nequ_)ior. Sinnius Capito ait Ti. Gracchum consulem, collegam P. Valeri Faltonis, Sardiniam Corsicamque subegisse, nec praedae quicquam aliud quam mancipia captum....’[399] Constitutional history interests him: ‘Tertia haec est interrogandi species, ut Sinnio Capitoni videtur, pertinens ad officium et consuetudinem senatoriam; quando enim aliquis sententiam loco suo iam dixerat, et alius postea interrogatus quaedam videbatur ita locutus....’[400]
