Ptolemy VI Philometor
Jewish apologetic literature can be traced back as far as Aristobulus of Paneas, though some discern it in the works of Demetrius the chronographer (3rd century BCE) traces of the style of "questions" and "solutions" typical of the genre. Aristobulus was a Jewish philosopher of Alexandria and the author of an apologetic work addressed to Ptolemy VI Philometor. Josephus's Contra Apion is a wide-ranging defense of Judaism against many charges laid against Judaism at that time, as too are some of the works of Philo of Alexandria.
