3. M.Calidius, son of No. 2 (Pseudo-Ascon. ad Cic. Verr. Act. 1.13), a celebrated orator, studied under Apollodorus of Pergamus, who was also the teacher of the emperor Augustus. (Euseb. Chron. Ol. 179. 2.)
Cicero passes (Brut. 79, 80) a high panegyric upon Calidius' oratory, which he characterizes at considerable length, and particularly praises the clearness and elegance of his style. But while Calidius explained a thing most lucidly, and was listened to with the greatest pleasure, he was pot so successful in carrying with him the feelings of his hearers and producing conviction. Vellcius Paterculus (2.36) classes him with Cicero, Hortensius, and the other chief orators of his time, and Quintilian (12.10.10) also speaks of the " subtilitas" of Calidius.
