Nor did he omit antiquarian tradition: ‘Sexagenarios (_de ponte olim deiciebant_): exploratissimum illud est causae quo tempore primum per pontem coeperunt comitiis suffragium ferre, iuniores conclamaverunt ut de ponte deicerentur sexagenarii qui iam nullo publico munere fungerentur...’,[401] and he is invoked as an authority on traditional law: ‘Sinnius Capito ait cum civis necaretur, institutum fuisse ut Semoniae res sacra fieret vervece bidente....’[402] Such were the shapers of the material taught in the schools. They epitomized the learning Varro had left, and boiled down the Vergilian commentaries of Servius, Macrobius, and Fulgentius. And if we do not know their number and their works too precisely, we may be fairly sure of the trend of their teaching. We may therefore leave them, adding just a word about dictionaries. M. Verrius Flaccus, the head of the court library under Augustus, had written a work _De Verborum Significatu_ in alphabetical order. Each letter took up several volumes. And in the middle of the second century, Pompeius Festus made an extract of this in twenty volumes, of which only a small part has been preserved, the original being wholly lost.[403] Verrius’s work was a standard one, as is shown by the frequent references to it in the grammarians.[404] It was frequently amplified and revised. ‘Scribonius Aphrodisius’, Suetonius tells us,[405] ‘was a teacher and a contemporary of Verrius, whose books on orthography he edited, criticizing his scholarship and his character.’ But it remained the foundation, and modifications of it must have been used by the teachers of the Gallic schools.
