as he is called by Tacitus, is mentioned as governor of Syria in A. D. 16, but was removed from the government by Tiberius in the following year on account of the connection of his family with Germanicus, inasmuch as a daughter of Silanus had been betrothed to Nero, the eldest of the children of Germanicus (Tac. Ann. 2.4, 43). From his names Creticus Silanus it has been conjectured that he originally belonged to the Junia gens, but was adopted into the Caecilia gens. It has been further supposed that he is the same person as the consul of A. D. 9 (D. C. 55.30). [METELLUS, No. 29.] In that case his full name would have been Q. Caecilius Metellus Creticus Silanus.
