Peripatetic school
Ptolemy-el-Garib (Arabic, more correctly "al-gharīb", "Ptolemy the foreigner," explained as meaning "Ptolemy the unknown") (fl. c300 AD) was a Hellenistic pinacographer, probably of the Peripatetic school, who wrote a "Life of Aristotle" notable for its catalog of Aristotle's works. This work survives in an Arabic manuscript in Istanbul.
