I have fourteen children, I am superior to Leto as she only has 2 children.
Niobe is the daughter of Tantalus, king of a town above Mount Sipylus in Anatolia. We are unaware of who her mother is. She has 2 brothers Broteas and Pelops.
As Niobe got older she married Amphion, they then had 14 children together. 7 sons and 7 daughters. When she got married and gave birth her life turned for the worse.
Niobe made a remark and the twins (Apollo and Artemis) felt as an insult and became very angry.
Apollo, the god of light and music came to Earth to get revenge, he murdered all 7 of her sons in front of her with his powerful arrows.
