We have no letters to or from Cicero in the years B.C. 64 and 63, partly, no doubt, because Atticus was in Rome a great deal during these years. We take up the correspondence, therefore, after an interval of two years, which in many respects were the most important in Cicero's life. In B.C. 62 his brother Quintus was praetor and Cicero defended in his court P. Sulla, accused of complicity with Catiline. On the 29th of December (B.C. 63) the tribune Q. Caecilius Metellus Nepos prevented Cicero from making a speech when laying down his consulship, and went on to propose summoning Pompey to Rome, "to protect the lives of the citizens." This led to scenes of violence, and Metellus fled to Pompey, who reached Italy late in the year B.C. 62 from the East.
