Ecphantus the Pythagorean in Wikipedia

Ecphantus or Ecphantos (Ancient Greek: Ἔκφαντος) is a shadowy Greek pre-Socratic philosopher. He may not have actually existed.[1] He is identified as a Pythagorean of the fourth century BCE, and as a supporter of the heliocentric theory. Described as from Syracuse, this may or may not be the same figure as the attested Ecphantus of Croton.
