Ecphantus or Ecphantos (Ancient Greek: Ἔκφαντος) or Ephantus (Έφαντος) was an Ancient Greek pre-Socratic philosopher.
He is identified as a Pythagorean of the 4th century BC from Syracuse, Magna Graecia, but the details concerning his life are historically obscure; he may have not been a historical person, but rather a fictional character invented by Heraclides of Pontus for use in his philosophical dialogues.
According to Eusebius, Ecphantus, like Heraclides of Pontus, was a supporter of the heliocentric theory: he believed that the Earth turns around its centre from west to towards east, like a wheel, as if it has an axis, the state.
[2] Ecphantus also maintained that there is only one Cosmos (Universe) governed by providence (πρόνοια).
