(Μνήμων), a physician of Side, in Pamphylia, who was a follower of Cleophantus, and lived in the third century B. C. (Galen, Comment. in Hippocr. " Epid. III." 2.4, 3.71, vol. xvii. pt. i. pp. 603, 606, 731). He is known only as one of the individuals whose name occurs in connection with the marks or characters (χαρακτῆρες) appended to certain medical cases in the third book of Hippocrates, " De Morbis Popularibus," of which Mnemon was by some persons (but probably without sufficient reason) supposed to be the author. (See Littré's Hippocrates,vol. i. p. 274.)
