Sípilo
Using arrows, Artemis killed Niobe's daughters and Apollo killed Niobe's sons. According to some versions, at least one Niobid (usually Meliboea, along with her brother Amyclas in other renderings) was spared. Their father, Amphion, at the sight of his dead sons, either killed himself or was killed by Apollo for having sworn revenge. Devastated, Niobe fled back to Mount Sipylus and was turned into stone, and, as she wept unceasingly, waters started to pour from her petrified complexion. Mount Sipylus indeed has a natural rock formation which resembles a female face, and it has been associated with Niobe since ancient times and described by Pausanias. The rock formation is also known as the "Weeping Rock" (), since rainwater seeps through its porous limestone.
