Happy Friday! Speaking of, here's the God of sleep. Hypnos was quite a lazy God, preferring to spend most of his time snoozing in his cave in the underworld. The entrance to his cave was lined with poppies and other hypnotic plants, and the river Lethe (river of forgetfulness) flowed through it. When not sleeping himself, Hypnos was busy putting Zeus to sleep at the request of his wife Hera, a habit Zeus was not very pleased with. Modern Words inspired by him: hypnosis, hypnagogia.
