He was twice accused of illegal practices in connexion with the elections; on the first occasion he was acquitted, in spite of his obvious guilt, through the eloquence of his uncle Quintus Hortensius; on the second he was condemned. He took the side of Caesar in the civil war. Nothing appears to be known of his later history. He was augur for fifty-five years and wrote a work on the science of divination.
