The two figures

Greek Pantheon

Selene

The Titan-born goddess of the moon, daughter of Hyperion and Theia and sister of Helios and Eos. She drives her team across the night sky, and poets tell of her love for the sleeping shepherd Endymion.

Selene was born to the Titans Hyperion and Theia, sister of Helios the sun and Eos the dawn. The Homeric Hymn to Selene adds that Zeus lay with her and that she bore a daughter, Pandia.

Selene is the moon itself, imagined as a goddess who bathes in Ocean and drives her horses across the sky at night. Hesiod places her with Helios and Eos among the children of Hyperion and Theia. The *Homeric Hymn to Selene* describes the radiance from her head filling the air and calls her full moon a sign and token to mortals, since the month was counted by her phases.

Japanese Pantheon

Tsukuyomi

God of the moon and night. Brother of Amaterasu and Susanoo. Represents night, time, and the lunar cycle. Ruler of the night realm.

Born from Izanagi's right eye during purification. Assigned to rule the night. His relationship with Amaterasu soured when he killed a goddess, causing sun and moon to separate.

**Tsukuyomi-no-Mikoto** rules over the night sky and the lunar realm, embodying the beauty and mystery of moonlight. Born alongside Amaterasu and Susanoo from their father Izanagi's purification ritual, Tsukuyomi emerged from the washing of Izanagi's right eye and was entrusted with dominion over the nocturnal world.
