Cornelius Nepos
The author of the abridged life of Cato, commonly considered the work of Cornelius Nepos, asserts that Cato, after his return from Africa, put in at Sardinia, and brought the poet Quintus Ennius in his own ship from the island to Italy. But because Sardinia is rather out of the line of the trip to Rome, it is more likely that the first contact between Ennius and Cato happened at a later date, when the latter was praetor in Sardinia.
