Themis was the daughter of Ouranos (Heaven) and Gaia (Earth). She told Zeus not to marry Metis, because the child of that union would be more powerful than Zeus himself; she agreed with him that the Trojan War was desirable in order to lighten an overburdened Earth; and she finally ended up marrying Zeus after he transformed his first wife into a fly and swallowed her. Themis played a very important role in Dodona. She was called Naia alongside Zeus and Dione (the owners of the sanctuary), so archaeologists have placed her temple right next to that of Zeus. It is a simple building with a frontal colonnade with four Ionic columns. A large altar stood in front of the temple.
