5. A native of Citium. respecting whom Suidas is in doubt whether he should be classed with the philosophers or the orators. He is said to have written the following works :-- Περὶ στάσεως. Περὶ σχημάτων. Ὑπόμνημα εἰς Ξενοφῶντα, εἰς Λυσίαν, εἰς Δημοσθένην. Περὶ ἐπιχειρημάτων. This Zenon is by some (Harles, in Fab. vol. iii. p. 581) identified with the Zenon spoken of in no very flattering terms by Ulpianus (in Dem. Proleg.), and with the physician of the same name who lived in the time of Julianus.
