Bion, Caecilius
a writer whose country is unknown, but who is mentioned by Pliny (Ind. to H. N. xxviii.) among the " Auctores Externi." Of his date it can only be said, that he must have lived some time in or before the first century after Christ. He wrote a work Περὶ Δυνάμεων, "On the Properties of Plants and other Medicines," which is not now extant, but which was used by Pliny. (H. N. 28.57.)
