"the speeches against Catiline"

 Catiline was a Roman politician from the 1st Century BC.  He conspired to overthrow the Roman Republic in 63BC, resorting to bribery and an assassination attempt on Cicero, who publicly denounced Cataline in what became known at the Catiline Orations.  There were four speeches in total, and Catiline himself was present during the first one, delivered in the Temple of Jupiter Stator.  This first speech contained an expression which has since become well known: O tempora, O mores (“Oh, what times, oh, what manners!”)!  Cataline’s attempts at a coup d’état subsequently failed; he died in battle a short time later against the Consul Quintus Caecilius Metellus Celer.
