Niobe, the daughter of the King Tanalos marries Thebai King Amphion and has 6 girls and 6 boys from this marriage. Her friend goddess Leto on the other hand has only two children namely Apollon and Artemis. During a festivity Niobe takes pride in having 12 children saying that Leto has only two. Leto, who is jealous of Niobe orders Apollon and Artemis to kill the children of Niobe and they kill 12 children of Niobe with their arrows. Niobe cries for days looking at the corpses of her children. In the end Zeus feels mercy for Niobe and turns her into a stone in order to relieve this pain. This rock, which is on the northwestern outskirts of Spil Mountain is one of the most visited places in the region.
