a friend of Cicero, who apprised him, on the information of C. Cassius, of a design to send a party of soldiers to his house at Tusculum. As this caution resembles a similar warning from M. Varro, Graeceius must have written to Cicero at the end of May, or the beginning of June, B. C. 44. (Cic. Att. 15.8, comp. ib. 5.) Cicero refers M. Brutus for information to Graeceius (ad Fam. 11.7).
