Lethe,Leto and Lelantos (the unseen trio)
LETHE -the personification of oblivion, forgetfulness, and concealment is a daughter of Oceanus and Eris. A river in the lower world likewise bore the name of Lethe.
LETO- one of the Titanides a bride of Zeus, and the mother of the twin gods Apollon and Artemis. She was the goddess of motherhood and, with her children, a protectress of the young. Her name and iconography suggest she was also a goddess of modesty and womanly demure. Like her sister Asteria she may also have been a goddess of the night, or alternatively of the light of day.
When Leto was pregant with the twins she was pursued relentlessly by the goddess Hera, who drove her from land to land preventing her from finding a place to rest and give birth. The floating island of Delos eventually provided her with refuge. Later when she was later travelling to Delphoi, the giant Tityos attempted to abduct her, but Apollon intervened and slew him with arrows.
In Greek vase painting Leto was usually depicted as a woman lifting her veil in a gesture of modesty. She was usually depicted accompanied by her two children. The exact meaning of her name is obscure, some commentators connect it with the word lethô, to move unseen, suggestive of modesty, others derive it from the Lycian word for woman, lada.
LELANTOS-one of the younger Titanes. He was probably the god of air, moving unseen and a hunter's skill at stalking prey. His daughter was the huntress Aura, goddess of the breeze.
Lelantos' name was derived from the Greek words lêthô, lanthanô, and lelathon, meaning "to escape notice," "move unseen" or "go unobserved." Lelantos may also have been associated with the Lelantian plain of Euboia.
Lelantos is apparently the male counterpart of Leto, just as his daughter, the virgin huntress Aura, is the counterpart of Leto's daughter Artemis.
