For that purpose, each of the sixteen cities of Elis sent a female envoy, "this woman to be the oldest, the most noble, and the most esteemed of all the women"; one of the delegates was Physcoa.
The Sixteen Women performed the establishment of peace, and were subsequently entrusted with management of the Heraean Games, particularly with ritual weaving of the robe for Hera.
Another of Pausanias' sources informs that it was Hippodamia who introduced the Heraean Games so as to express gratitude to Hera for arranging her marriage to Pelops, and assembled the Sixteen Women as co-founders of the tradition.
When Narcaeus grew up, it is related, he conquered many neighboring peoples and gained a lot of power; he was also credited with founding the sanctuary of Athena Narcaea.
Pausanias mentions that various honors were paid to Physcoa, and these included making her the eponym of the ritual dance.
