Hypnos: God of Sleep is the latest offering of the Mythos series, and includes 12 eyeshadows, 4 cheek/face products and 4 lip products. Hypnos was the ancient Greek personification of sleep, and was the son of the Goddess Nyx.

In Greek myth, he is described as living in the underworld- in a dark, musty cave through which flowed the waters of Lethe, the river of forgetfulness. Hypnos lay on his soft couch, surrounded by his many sons (the Oneroi), who were the bringers of dreams. The entrance to his cave was said to be surrounded by various soporific plants and herbs, which he used to bring sleep.
