Bion of Borysthenes
Biography: Bion of Borysthenes, c. 325 c. 250 BC, was a Greek philosopher. After being sold into slavery, and then released, he moved to Athens, where he studied in almost every school of philosophy. It is, however, for his Cynic-style diatribes that he is chiefly remembered. He satirized the foolishness of people, attacked religion, and eulogized philosophy.
