Cichol Gricenchos

In Irish mythology, is Cichol or Cíocal Gricenchos the earliest-mentioned leader of the Fomorians. His epithet, Gricenchos or Grenchos, is obscure but may mean "withered foot" or "footless".

Seathrún Céitinn records a tradition that he arrived in Ireland one hundred years after the Flood, with fifty men and fifty women on six boats. His people lived on fish and fowl for two hundred years until Partholón, bringing the plough and oxen, invaded and defeated them in the Battle of Magh Ithe.
