 Ahenobarbus was the elected magistrate presiding over the trial against Titus Annius Milo in 52 for the murder of Publius Clodius, as related by Asconius' summary of Cicero's "Pro Milone".For the next two or three years during Cicero's absence in Cilicia, information about Ahenobarbus is principally derived from the letters of his enemy Coelius to Cicero.In 50 he was a candidate for the place in the college of augurs left vacant by the death of Quintus Hortensius, but was defeated by Mark Antony through the influence of Caesar.
