Cicero,[8] writing in the 1st century BC, tells of how a friend of Diagoras tried to convince him of the existence of the gods, by pointing out how many votive pictures tell about people being saved from storms at sea by "dint of vows to the gods", to which Diagoras replied that "there are nowhere any pictures of those who have been shipwrecked and drowned at sea." And Cicero goes on to give another example, where Diagoras was on a ship in hard weather, and the crew thought that they had brought it on themselves by taking this ungodly man on board. He then wondered if the other boats out in the same storm also had a Diagoras on board.[9]
