Memphis worshipped the god Ptah. The great sanctuary of the god at that city was held to be as ancient as the city itself. So far back as our knowledge extends, the Pharaohs were occupied with the extension and adornment of this temple. Among the Greeks the god of Memphis was known as Hephæstus: they tell us he was represented in the temple by a dwarf-like image; and that similar images of the children of Ptah stood in a part of the temple only entered by the priests.[34] The name Hephæstus, and the further statement of the Greeks, that this god was the father of the Sun-god, prove that in Ptah the Egyptians worshipped not only fire, but the spirit of warmth and light generally; and that they must have regarded him as the origin and source of light. Manetho puts Ptah at the head of the dynasties of the gods. He ruled for 9,000 years before the other gods. Inscriptions name Ptah "the lord of truth," the "father of truth," the "ruler of the sky," "the king of both worlds." As the god of the light which shows everything in its true form, he is the spirit of truth; as the spirit of the light in the sky, he is the lord of heaven. The inscriptions also say that Ptah "moves the egg of the sun and the moon;" he is called "the weaver of the beginnings," the "god who rolls his egg in the sky." Consequently, to the Egyptians Ptah was the mover of the luminaries, a formative, creative spirit, and as he is called in the inscriptions "the father of the father of the gods," he must have been to them the first and oldest god, the beginning of the gods and of all things. The Egyptians believed that a kind of beetle peculiar to their country (_scarabæus sacer_) was propagated without the female sex; they saw the mode of its reproduction in the balls of dung which the beetles occasionally pushed before them. Hence they consecrated this insect to their god of beginning and creation, and on monuments and records we find the god Ptah with a beetle on his shoulders, in the place of a human head. As the god of the beginning he appears on monuments in the shape of a child or dwarf; and again, as the unchangeable god, he is wrapped in the casings of a mummy, with the symbols of dominion, the whip and sceptre, or the so-called Nile-gauge, a ring with parallel cross bars, in his hand, in order to denote him as the god who gives to all things measure, order, and law. He is also coloured green, to signify, as it would seem, that lie is a god favourable to vegetation, and possessed of a fertilising power.
