The Oneiroi were primordial deities in Greek mythology, children of Nyx (night) alone, and had numerous siblings, including Hypnos (sleep), Thanatos (death), and Geras (old age). They were the personifications of dreams and according to Euripides, they had the form of black - winged daemons. Based on the Latin poet Ovid, some of the Oneiroi were Morpheus (who presented human images), Phobetor (who presented beasts, birds and serpents) and Phantasos (who presented items made of the elements earth, rock, water and wood). In the Odyssey, the dreams were mentioned as coming through a gate of horn if they were true, or through a gate of ivory if they were false.
