One of the most important subjects that the ancient Greeks wondered and wanted to learn is how the World was created . For them, the formation process of earth, sky, Sea, water, light, air, night, day, gods and humans has always been important. When we look at this process, there is chaos -the infinity- at the beginning of the world. From this infinity, first Mother Earth, then the deepest place of the world of the dead, then the underground darkness and the darkness of the earth, Night (Nyx) were born. Mother Earth herself gave birth to sky, sea, and mountains, then to divine beings, later uniting with her own children. Nyx, with rarer qualities and powers than other gods and goddesses, can do good or evil to humanity. It can put people to sleep or kill them. Night (Nyx), which is generally seen as one of the goddesses that should be avoided and feared, shapes other intangible beings with various duties and responsibilities in the world that continues to be created with the method of self-generation (parthenogenesis) in this process. In our study, these virginally generated beings by Night are discussed.
