the patronus of the Allobroges, was the person to whom the ambassadors of the Allobroges disclosed the treasonable designs of the Catilinarian conspirators. Sanga communicated the intelligence to Cicero, who was thus enabled to obtain the evidence which led to the apprehension and execution of Lentulus and his associates, B. C. 63. Q. Sanga is mentioned as one of the friends of Cicero who besought the con sul L. Piso, in B. C. 58, not to support Clodius in his measures against Cicero. (Sall. Cat. 41 ; Appian, App. BC 2.4; Cic. in Pis. 31.)
