TIRO.
M. Tullius Tiro, the freedman of Cicero, who had a high opinion of his worth and ability (ad Fam. xvi. 4, 3; ad Att. vii. 5, 2), wrote (1) a biography of his patron: Ascon. p. 49, ‘ut legimus apud Tironem libertum Ciceronis in libro iiii. de vita eius.’
(2) Editions of Cicero’s speeches and letters: Gell. i. 7, 1, ‘in oratione Ciceronis v. in Verrem, libro spectatae fidei, Tironiana cura atque disciplina facto.’ (See also [p. 85].)
(3) A collection of Cicero’s witticisms: Quint. vi. 3, 5, ‘utinam libertus eius Tiro aut alius, quisquis fuit, qui iii. hac de re libros edidit, parcius dictorum numero indulsissent.’
(4) Grammatical works, as πανδέκται, mentioned by Gell. xiii. 9, 2.
For his system of shorthand, cf. Sueton. p. 136 R., ‘Romae primus Tullius Tiro, Ciceronis libertus, commentatus est notas, sed tantum praepositionum.’
