Demophon ruled the Greek colony of
Elaeus in the Thracian Chersonnese (now known as the
Gallipoli peninsula) when a destructive plague hit the city, claiming the lives of many people. Troubled, he sought the advice of the oracle of
Apollo, and the god informed him that each year they had to sacrifice a nobleborn maiden to their ancestral gods in order to stop it. Demophon did as told and selected the unfortunate girls by lot, but he always made sure to exclude his own daughters. This went on until a nobleman named
Mastusius took offence and declared he would not have his daughter entered in the drawing unless Demophon's daughters were as well. Demophon was enraged, so he sacrificed Mastusius' daughter without drawing lots at all. Mastusius was greatly angered, but he concealed his resentment out of patriotism for some time, claiming his daughter might have ended up being chosen anyway. Demophon himself forgot the incident as Mastusius adopted an amicable endeavor around him, so when Mastusius invited him and his daughters for a solemn sacrifice, he agreed. Demophon told his daughters to go first ahead of him, as he still had some duties to attend to before he could go. Mastusius seized the girls when they arrived and killed them all, and then had their blood mixed with wine in a bowl. When Demophon arrived, he asked for his daughters, and the bowl was offered to him to drink. When he learnt what had happened, he ordered both Mastusius and the bowl to be thrown into the sea; the cape was called Mastusian after the nobleman, and the harbour the Bowl after the wine vessel. The bowl also found a place among the stars too, as the constellation
Crater (The Wine-cup). == Culture ==
