Cornelius Nepos (c. 100 –c. 25 BC) was a Roman biographer. He was born at Hostilia, a village in Cisalpine Gaul not far from Verona. His Gallic origin is attested by Ausonius, and Pliny the Elder calls him Padi accola ("a dweller on the River Po", Natural History III.22). He was a friend of Catullus, who dedicates his poems to him (I.3), Cicero and Titus Pomponius Atticus. Eusebius places him in the fourth year of the reign of Augustus, which is supposed to be when he began to attract critical acclaim by his writing. Pliny the Elder notes he died in the reign of Augustus (Natural History IX.39, X.23).
