One of the enduring mysteries of Atlantis is the identity of Cleito, who married Poseidon.
Cleito is derived from (Ma)-at-ka-re or ka-re-(Ma)-at. Hatshepsut or Maatkare is Cleito. She is also Athena. On a side note: her husband Thutmose II is Poseidon.
She is also the founder of Atlantis; She rebuilds Avaris, and renames it to Atlantia.

Here are the rings of Atlantis, btw. They come from a picture of the Pleiades, or stars from Senmut's tomb:
