Angels-HYPNOS

The Greek god Hypnos (Sleep), son of Nyx (Night) and brother of
Thanatos (Death), and from whom we derive the term hypnosis, was
traditionally pictured as making his home in a dark, misty cave,
through which flowed the River of Forgetfulness. He was surrounded
by his numberless sons, the Dreams. As a messenger of the gods, Hypnos
was pictured with wings. He had few myths associated with him—
putting Zeus to sleep at the behest of Hera on several occasions and
once helping his brother Thanatos carry the body of Apollo’s son
Sarpendon from a battlefield.
