2. C.Decimius, was sent in B. C. 171 as ambassador to Crete to request the Cretans to send auxiliaries for the war against Perseus of Macedonia. In 169 he was praetor peregrinus, and ill the year following he was sent with two others as ambassador to Antiochus and Ptolemy, to bring about a reconciliation between the two kings, and to declare that, whichever of them should continue hostilities, should cease to be treated as the friend and ally of Rome. On that occasion Decimius and his colleagues visited the island of Rhodes at the request of the Rhodians themselves, and on his return to Rome his report was in favour of the Rhodians, in as much as he endeavoured to throw the guilt of their hostility towards Rome upon some individuals only, while he tried to exculpate the body of the people. (Liv. 42.35, 43.11, 15, 44.19, 45.10.)
