Publius Cornelius Lentulus Sura  Publius Cornelius Lentulus Sura (114 BC – 5 December 63 BC), was one of the chief figures in the Catilinarian conspiracy and was also the adopted father of the future triumvir Mark Antony. When accused by Sulla (to whom he had been quaestor in 81 BC) of having squandered the public money, he refused to render any account, but insolently held out the calf of his leg ("sura"), on which part of the person boys were punished when they made mistakes in playing ball, akin to inviting a slap on the wrist. He was praetor in 75 BC, governor of Sicily in 74 BC, and consul in 71 BC. In 70, being expelled from the senate with a number of others for immorality, he joined Catiline. Relying upon a Sibylline oracle that three Cornelii should be rulers of Rome, Lentulus regarded himself as the destined successor of Lucius Cornelius Sulla and Lucius Cornelius Cinna. When Catiline left Rome after Cicero's second speech "In Catilinam", Lentulus took his place as chief of the conspirators in the city. In conjunction with C. Cornelius Cethegus, he undertook to murder Cicero and set fire to Rome, but the plot failed owing to his timidity and indiscretion. Ambassadors from the Allobroges being at the time in Rome, the bearers of a complaint against the oppressions of provincial governors, Lentulus made overtures to them, with the object of obtaining armed assistance. Pretending to fall in with his views, the ambassadors obtained a written agreement signed by the chief conspirators, and informed Q. Fabius Sanga, their "patron" in Rome, who in his turn acquainted Cicero. The conspirators were arrested and forced to admit their guilt. Lentulus was compelled to abdicate his praetorship, and, as it was feared that there might be an attempt to rescue him, he was put to death in the Tullianum on 5 December 63 BC, along with other senatorial supporters of Catiline. The legitimacy of these killings, which were carried out on the personal command of the consuls and without a judicial trial, was disputed. Cicero argued that his actions were lawful under the "Senatus consultum ultimum", but was exiled in 58 BC after the people's tribune, Publius Clodius Pulcher, Cicero's bitter enemy, passed a law prohibiting extrajudicial killings of Roman citizens, and then accused Cicero of having violated it.
