a physiognomist mentioned by Abú-l-Faraj (Hist. Dynast. p. 56), as having said that the portrait of Hippocrates (which was shown him in order to test his skill) was that of a lascivious old man; the probable origin of which story is explained under HIPPOCRATES, p. 484. He is also said by the same author to have written a work on Physiognomy which was extant in his time in a Syriac translation (see Wenrich, De Aucrtor. Graecor. Version. Arab. Syriac. Pers. &c. p. 296); and there is at present an Arabic MS. on this subject in the library at Leyden which bears the name of Philemon, but which ought probably to be attributed to Polemo. [POLEMO.] (See Catal. Bibliotf. Lugdun. p. 461.1286; and also the Index to the Catalogue, where the mistake is corrected.)
