Hermotimus of Clazomenae (c. 6th century BCE), called by Lucian a Pythagorean, was a philosopher who first proposed, before Anaxagoras (according to Aristotle) the idea of mind being fundamental in the cause of change.
The iatromantis, a form of Greek shaman, is related to other semimythical figures such as Abaris, Aristeas, Epimenides, and Hermotimus.
