AULUS CAECINA, son of Aulus Caecina, who was defended by Cicero (6g B.c.) took the side of Pompey in the civil wars and published a violent tirade against Caesar, for which he was banished. He recanted in a work called Querelae, and was par doned at the intercession of his friends—above all, of Cicero. Caecina was regarded as an authority on the Etruscan system of divination (Etrusca Disciplina), which he tried to harmonize with the doctrines of the Stoics. (See Seneca, Nat. Quaest. II, for fragments.) Cicero was probably indebted to Caecina in his treatise De Divinatione. Some of the correspondence is preserved in Cicero's letters (Ad Fem. vi. 5-8; see also ix. and xiii. 66) .
