Epimenides of Cnossos was a semi-mythical 7th or 6th century BC Greek seer and philosopher-poet, from Knossos or Phaistos. Several prose and poetic works, now lost, were attributed to Epimenides, including a theogony, an epic poem on the Argonautic expedition, prose works on purifications and sacrifices, a cosmogony, oracles, a work on the laws of Crete, and a treatise on Minos and Rhadymanthus.
