The Cult
No ancient city organized a festival of Stýx; her cult was the cult of the oath. Warriors and envoys swore by her water, and the Arcadian waterfall near Nonakris was shown to visitors as the actual stream by which the gods themselves bound their word. Libation and curse rites accompanied serious oaths, but temples, priesthoods, and regular sacrifice are absent from the record. Her power lay in the terrifying idea that even Olympians could not break a vow sworn in her name.
