Pausanias Description of Greece 1.37.4

[4]
  Across the Cephisus is an ancient altar of Zeus Meilichius (Gracious). At this altar Theseus obtained purification at the hands of the descendants of Phytalus after killing brigands, including Sinis who was related to him through Pittheus. Here is the grave of Theodectes ¹ of Phaselis, and also that of Mnesitheus. They say that he was a skilful physician and dedicated statues, among which is a representation of Iacchus. On the road stands a small temple called that of Cyamites. ² I cannot state for certain whether he was the first to sow beans, or whether they gave this name to a hero because they may not attribute to Demeter the discovery of beans. Whoever has been initiated at Eleusis or has read what are called the Orphica ³ knows what I mean.

I cannot state for certain whether he was the first to sow beans, or whether they gave this name to a hero because they may not attribute to Demeter the discovery of beans. Whoever has been initiated at Eleusis or has read what are called the Orphika knows what I mean.
