a "☥" shaped amulet with a looped upper half. The ankh, it was believed, was surrendered with death, but could be preserved in the corpse with appropriate mummification and funerary rites. The supremacy of Re in the Egyptian pantheon was at its highest with the 5th Dynasty, when open-air solar temples became common. In the Middle Kingdom of Egypt, Ra lost some of his preeminence to Osiris, lord of the West, and judge of the dead. In the New Empire period, the Sun became identified with the dung beetle, whose spherical ball of dung was identified with the Sun. In the form of the sun disc Aten, the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton. The Sun's movement across the sky represents a struggle between the Pharaoh's soul and an avatar of Osiris. Ra travels across the sky in his solar-boat; at dawn he drives away the demon king Apep. The "solarisation" of several local gods (Hnum-Re, Min-Re, Amon-Re) reaches its peak in the period of the fifth dynasty. Rituals to the god Amun, who became identified with the sun god Ra, were often carried out on the top of temple pylons. A pylon mirrored the hieroglyph for 'horizon' or akhet, which was a depiction of two hills "between which the sun rose and set," associated with recreation and rebirth. On the first pylon of the temple of Isis at Philae, the pharaoh is shown slaying his enemies in the presence of Isis, Horus, and Hathor.
