Medusa part of their religion. Medusa was beheaded by the hero Perseus, who thereafter used her head, which retained its ability to turn onlookers to stone, as a weapon until he gave it to the goddess Athena to place on her shield. In classical antiquity the image of the head of Medusa appeared in the evil-averting device known as the "Gorgoneion". The three Gorgon sisters—Medusa, Stheno, and Euryale—were all children of the ancient marine deities Phorcys (or "Phorkys") and his sister Ceto (or "Keto"), chthonic monsters from an archaic world. Their genealogy is shared with other sisters, the Graeae, as in
Sisters of Mary of the Presentation for elderly Sisters. Before the remaining Sisters could be evicted, World War I (1914-1918) broke out and spread across Europe. The Motherhouse was conscripted by the government for use as a military hospital, named “Complementary Hospital #42.” Because the government had seized the Sisters’ possessions the Motherhouse had no furnishings, so the Sisters appealed to the people of Broons. Days before the first wounded arrived the townsfolk of Broons, and other nearby communities, donated the furnishings necessary for the Sisters to care for the wounded. Many of the Sisters exiled to foreign lands returned to care for the wounded soldiers.
