Sopdu

Sopdu (also rendered Septu or Sopedu) was a god of the sky and of eastern border regions in ancient Egyptian religion.<ref name=Wilkinson 211">Wilkinson, Richard H. (2003). The Complete Gods and Goddesses of Ancient Egypt. Thames & Hudson. p. 211</ref>

As a sky god, Sopdu was connected with the god Sah, the personification of the constellation Orion, and the goddess Sopdet, representing the star Sirius. According to the Pyramid Texts, Horus-Sopdu, a combination of Sopdu and the greater sky god Horus, is the offspring of Osiris-Sah and Isis-Sopdet.<ref name=Wilkinson 211"/>

As a god of the east, Sopdu was said to protect Egyptian outposts along the frontiers and to help the pharaoh control those regions' foreign inhabitants. He was referred to as Lord of the East, and had his greatest cult centre at the easternmost nome of Lower Egypt, which was named Per-Sopdu, meaning place of Sopdu. He also had shrines at Egyptian settlements in the Sinai Peninsula, such as the turquoise mines at Serabit el-Khadim.<ref name=Wilkinson 211"/>
