2. C.CaeliusCaldus, a son of L. Caelius Caldus, and a grandson of No. 1, was appointed quaestor in B. C. 50, in Cilicia, which was then under the administration of Cicero. When Cicero departed from the province, he left the administration in the hands of Caldus, although he was not fit for such a post either by his age or his character. Among the letters of Cicero, there is one (ad Fam. 2.19) addressed to Caldus at the time when he was quaestor designates. (Cic. Fam. 2.15, ad Att. 6.2, 4-6, 7.1.)
