In Greek mythology, the Niobids were the children of Amphion of Thebes and Niobe, slain by Apollo and Artemis because Niobe, born of the royal house of Phrygia, had boastfully compared the greater number of her own offspring with those of Leto, Apollo's and Artemis' mother: a classic example of hubris.[1]
