This scarab is dedicated to a sun-god, most likely Ra, who was considered the first pharaoh of Egypt. This is highlighted by the use of the obelisk hieroglyph, which was symbolic of the sun-god. Egyptian obelisks were often carved from a single stone, usually red granite, and topped with a gold or electrum cap. This would reflect the rays of the sun and re-inforce the connection to Ra.
Ra was one of the most important deities within the Egyptian pantheon. He was depicted as a falcon-headed male and bore similarities to Horus. He held dominion over the sun and sky and his rule extended to kingship and order, in his role as first pharaoh.
