Our knowledge of the life of Terence is derived chiefly from a fragment of the lost work of Suetonius, _De viris illustribus_, preserved in the commentary of Donatus. Confirmation of some of the statements contained in the life is obtained from later writers and speakers, and also from the prologues to the different plays, which throw light on the literary and personal relations of the poet. These prologues were among the original sources of Suetonius: but he quotes or refers to the works of various grammarians and antiquarians--Porcius Licinus, Volcatius Sedigitus, Santra, Nepos, Fenestella, Q. Cosconius--as his authorities. The first two lived within a generation or two after the death of Terence, and the first of them shows a distinct animus against him and his patrons. But notwithstanding the abundance of authorities, there is uncertainty as to both the date of his birth and the place and manner of his death. The doubt as to the former arises from the discrepancy of the MSS. His last play, the Adelphoe, was exhibited in 160 B.C. Shortly after its production he went to Greece, being then, according to the best MSS., in his twenty-fifth ('nondum quintum atque vicesimum egressus[6] annum'), according to inferior MSS., in his thirty-fifth year. This uncertainty is increased by a discrepancy between the authorities quoted by Suetonius. Cornelius Nepos is quoted for the statement that he was about the same age as Scipio (born 185 B.C.) and Laelius, while Fenestella, an antiquarian of the later Augustan period, represented him as older. As the authority of the MSS. coincides with that of the older record, the year 185 B.C. may be taken as the most probable date of his birth. In the case of an author drawing originally from life, it might seem improbable that he should have written six comedies, so true in their apprehension and delineation of various phases of human nature, between the ages of nineteen and twenty-five. But the case of an imitative artist reproducing impressions derived from literature is different; and the circumstances of Terence's Phoenician origin and early life may well have developed in him a precocity of talent. His acknowledged intimacy with Scipio and Laelius, and the general belief that they assisted him in the composition of his plays, agree better with the statement that he was about their own age than that he was ten years older. The lines at the end of the prologue to the Heauton Timorumenos-- Exemplum statuite in me ut _adulescentuli_ Vobis placere studeant potius quam sibi, indicate that he was a very young man when they were written. Thus Terence may, more even than Catullus or Lucan, be ranked among 'the inheritors of unfulfilled renown.'
