- Cleito is based on a figure from the Greek legend of Atlantis, as recorded in the dialogue Critias by Plato. Cleito was reportedly a mortal girl, daughter of Evenor and Leucippe. The god Poseidon fell in love with Cleito and took her as his mate. They had a number of mortal children together, which were granted the uninhabited island of Atlantis by Poseidon. The island was named after Cleito's firstborn son Atlas, who inherited the kingdom. All subsequent kings of Atlantis were reportedly male-line descendants of Atlas.
- While Plato claimed to have learned the legend of Atlantis through the records of his ancestor Solon (c. 638–558 BC), who in turned heard it from the priests of Sais in Egypt, modern historians suspect that Plato himself invented the legend and its characters.
