Menedemos was a pupil of Colotes of Lampsacos [a pupil of Epicurus who also studied Cynicism in 3-4th century BC].
According to Hippobotos, he advanced to such a degree of imposture that he went around in the guise of a Fury [an ancient chthonic goddess of vengeance], saying that he had come from Hades to take note of sins that were committed, so as to be able to report them, on his return, to the deities below.
This was the manner of his dress: he wore a dark [grey or black] tunic reaching down to his feet, with a red [lit. Phoenician, i.e., Tyrian purple] belt tied around it, and an Arcadian hat on his head with the twelve signs of the zodiac embroidered on it, and tragic buskins, and he had an enormously long beard, and carried an ash-wood staff in his hand.
