(ὁ Μασσαλιώτης), or MASSILIENSIS, a native of Marseilles, and the author of several medical formulae preserved by Galen, must have lived in or before the first century after Christ, as he is by Asclepiades Pharmacion. (Gal. De Compos. Medicam. sec. Gen. 5.15. vol. xiii. p. 856.) By some persons he is supposed to be the same as Demosthenes Philalethes, which seems to be quite possible. He is sometimes called simply Massaliotes or rassiliensis. (Gal. l.c. p. 855; Aetius, 4.2. 58, p. 726.) See C.G.Kühn, Additam. ad El/ench. Msedicor. Veter. a J. A. Fabricio, §c., exhibitum, where he has collected all the fragments of Demosthenes that remain.
