This is the OCR-endorsed edition covering the Latin AS and A-Level (Group 1) prescription of Cicero's pro Caelio, 51–58, 61–68, and the A-Level (Group 2) prescription of 33–50, giving full Latin text, commentary and vocabulary, with a detailed introduction that also covers the prescribed material to be read in English for A Level. Pro Caelio is one of Cicero’s finest and funniest speeches. In 56 BC, he defended Marcus Caelius Rufus who was being prosecuted on charges of violence, including the attempted poisoning of Roman noblewoman Clodia with whom Caelius previously had an affair. Cicero’s primary tactic was to blacken the character and reliability of Clodia, whom he depicts as the woman scorned, prosecuting Caelius out of revenge. Drawing on characters well known from Roman comedy, Cicero casts Caelius as the decent young man victimized by the aggressive courtesan, thereby shaming Clodia and glossing over the more awkward charges levelled at his client.
