The primordial gods or "Protogenoi" of Greek mythology were the most basic components of the universe which emerged fully-formed at creation. They included Earth, Air, Sea, Sky, Fresh Water, Underworld, Darkness, Night, Light, Day, Procreation and Time.
​
The first born of the immortals, who formed the very fabric of the universe, were known in Greek mythology as the Protogenoi (protos meaning "first," and genos "born"). They were, for the most part, purely elemental beings - Uranus was the literal sky, Gaea the body of the earth, etc. A few of them were ocassionally described or portrayed in anthropomorphic form, however these forms were inevitably inseperable from their native element. For example Gaea or Thalassa might appear as a woman half risen from the earth or sea.
