Re (Ra) was the solar god from Heliopolis and a ma- jor deity all over Egypt.
Every day he traveled over the sky in his boat with his sundisc. He stood for the rising sun, life, rebirth, chil- dren, health, virility etc, and the myths about him were several. In the fifth dynasty the pharaoh took the title - son of Re, and this lasted right to the end of Egyptian history. During the New Kingdom he was combined with Amon and became Amon-Re and Horus as Re-Horakhte.
In later times he got a wife called Ret, and she looked just like Hathor. One of the many aspect of him was the god Atum and as a creator all humans were created from Re's tears or sweat.
