Lucullus (1.5-1.6)

Now, as to his love of literature, this also is reported, in addition to what has already been said: when he was a young man, proceeding from jest to earnest in a conversation with Hortensius, the orator, and Sisenna, the historian, he agreed, on their suggestion of a poem and a history, both in Greek and Latin, that he would treat the Marsic war in whichever of these forms the lot should prescribe. And it would seem that the lot prescribed a Greek history, for there is extant a Greek history of the Marsic war.

Of his affection for his brother Marcus there are many proofs, but the Romans dwell most upon the first. Although, namely, he was older than his brother, he was unwilling to hold office alone, but waited until his brother was of the proper age, and thus gained the favour of the people to such an extent that, although in absence from the city, he was elected aedile along with his brother.
