The stone vomitted by cronus is the stone of

In greek mythology, Cronus vomited the stone replacement of Zeus. Cronus was the leader of all the titans, father to the Gods. He did not want any of his child to replace him as ruler so each time his wife gave birth he swallowed them whole. Zeus was the only exception as during childbirth he was replaced with a stone wrapped in robe to make it seem it was him, that Cronus had swallowed at that time.
