Apollonius (a-po-lo'-ne-us), called the Rhodian (Apollonius Rhodius), was born in Alexandria, B.C. 230. He presided over an academy at Rhodes, was an eminent rhetorician, and wrote a poem in four books, on the expedition of the Argonauts, and other poems. This name was also borne by a mathematician of Perga in Pamphylia, who lived in 240 B.C.; by a Roman senator and Christian martyr, who suffered in 186; and by a sophist, a stoic, and a Pythagorean philosopher.
