Poseidon

Poseidon is the "husband of Da", or Don, goddess of the Earth.  She evolves into Da-Mater, a younger child-bearing age version of Dea Mater, Mother of the Gods.    She is an aspect of her Mother, Rhea, even as Kore is an aspect of Demeter.  A  different theory is that his name means "Lord of the Waters".

The energies of Pegasus are as much about the hidden Poseidon-Neptune-water-freedom-victory energy,
Poseidon Consort of the Mother as fertile, generous, abundant enlivener, and Medusa as Queen, the hidden or repressed Mother aspect of the warrior goddess who is transformed into an apotropaic demon that repels evil,
remaining a decorative element on city walls and fulfilling a function as a protective aspect of the City Goddess.
Protector, Helper, Liberator, Giver of the Waters of Truth and Beauty, Bringer of Rain in Spring, Inspiration, and Lightning.

Cleito

Cleito, a mortal woman,  was the daughter of Evenor and Leukippe, who dwelt on the central mountain of the island of Atlantis.

 With Poseidon, Cleito gave birth to five pairs of twin boys who became the rulers of Atlantis.   Their names were: Atlas and Eumelus (or Gadeirus); Ampheres, and Evaemon; Mneseus, and Autokhthon (Autochthon); Elasippus, and Mestor; and, finally, Azaes and Diaprepes.

Cleito's descendants were the rulers of Atlantis and the surrounding seas for untold generations.

Cleito and Atlantis are mentioned in the Kritias by Plato.

Psyche: Magical Journeys of the Goddess

the Psyche series of liturgies has an interesting structure.  Its two parts are dedicated to The Spiral of Tiamat and The Rays of Ishtar.  The earth and the stars.

The glyph of the Fellowship of Isis depicts an eight pointed star  with a spiraling dragon coiling around it.  In part one, this spiral progresses from the earth...to the moon...to the sun...to the galaxy. Part two takes us beyond the galaxy to Sirius, brightest star in our sky, and mystical gateway to the seven levels of consciousness that arer represented by the jewels (or rays) of Ishtar.

Seven constellations correspond to these jewels. Pegasus is one of them.
