Aker (Akeru, Akerui)
The double lion god
Depiction: Depictions showed Aker as a double-headed lion or two lions sitting back-to-back with the sun and sky appearing between them. The two lions form the Egyptian symbol for the sky, akhet. The lions were named Sef (Yesterday) and Duau (Today).
Mythology: The Egyptian believed that Aker, an earth-god, guarded the gates of dawn and sunset through which the sun rose every morning and set every evening. The ancient Egyptians placed statues of Aker at the doors of palaces and tombs to ward off evil spirits and malicious entities. Statues of Aker often were given the heads of men and women, which the ancient Greeks referred to as sphinxes.
