TIRO, M. Tullius, the secretary of Cicero. He was not only the amanuensis of the orator, and his assistant in literary labor, but was himself an author of no mean reputation, and the inventor of the art of shorthand, which made it possible to take down fully and correctly the words of public speakers, however rapid their enunciation. After the death of Cicero, Tiro purchased a farm in the neighborhood of Puteoli, to which he retired and lived, according to Hieronymous, until he reached his hundredth year. Asconius Pedianus (in Pro Milone 38) refers to the fourth book of a life of Cicero by Tiro.

Innumerabilia tua sunt in me officia, domestica, forensia, urbana, provincialia, in re privata, in publica, in studiis, in litteris nostris.

“Your services to me are beyond count-in my home and out of it, in Rome and abroad, in private affairs and public, in my studies and literary work.”
