It is said that in the ritual of Zoroaster the great expanse of the heavens, and even nature itself, was described under the symbol of a serpent.[2] The like was mentioned in the Octateuch of Ostanes; and moreover, in Persia and in other parts of the East they erected temples to the serpent tribe, and held festivals to their honour, esteeming them _the supreme of all Gods, and the superintendents of the whole world_. The worship began among the people of Chaldea. They built the city Opis upon the Tigris, and were greatly addicted to divination and to the worship of the serpent. From Chaldea the worship passed into Egypt, where the serpent deity was called Canoph, Caneph, and C'neph. It had also the name of Ob, or Oub, and was the same as the Basilicus, or Royal Serpent; the same also as the Thermuthis, and in like manner was made use of by way of ornament to the statues of their Gods. The chief Deity of Egypt is said to have been Vulcan, who was also styled Opas, as we learn from Cicero. He was the same as Osiris, the Sun; and hence was often called Ob-El, or Pytho Sol; and there were pillars sacred to him, with curious hieroglyphical inscriptions, which had the same name. They were very lofty, and narrow in comparison of their length; hence among the Greeks, who copied from the Egyptians, everything gradually tapering to a point was styled Obelos, and Obeliscus. Ophel (Oph-El) was a name of the same purport, and many sacred mounds, or Tapha, were thus denominated from the serpent Deity, to whom they were sacred.
