Meaning and history
Greek form of Egyptian ꜣst (reconstructed as Iset, Aset or Ueset), possibly from st meaning “throne.” In Egyptian mythology, Isis was the goddess of the sky and nature, the wife of Osiris, and the mother of Horus. She was first shown with a throne-shaped headdress, but in later periods she was identified with Hathor and depicted with cow horns on her head. She was also worshipped beyond Egypt, including by the Greeks and Romans.
Isis moved from #575 to #704 for girls between 2013 and 2014. Its highest annual birth count came in 2005, with 561 births.
