the Titans Phoebe and Coeus with whom Zeus fell in love with but banished
when she became pregnant for fear of Heras wrath. Leto found no place that
would accept her and finally escaped to a floating island, Delos, where she
gave birth to Apollo and Artemis clutching to a palm tree. From then on Delos
was attached to the seafloor.
When Niobe said she, who had six sons and six daughters, was better than Leto who only had two childern Apollo and Artemis killed the children with their arrows.
Tityos had tried to rape Lato when she was going to Delphi but Apollo warned her and Zeus punished Tityos by streching him on a field with two birds hacking his liver.
