Horus, also known as Heru, Har, Her, or Hor in Ancient Egyptian, is one of the most significant ancient Egyptian deities who served many functions, most notably as the god of kingship, healing, protection, the sun, and the sky. He was worshipped from at least the late prehistoric Egypt until the Ptolemaic Kingdom and Roman Egypt. Different forms of Horus are recorded in history, and these are treated as distinct gods by Egyptologists. These various forms may be different manifestations of the same multi-layered deity in which certain attributes or syncretic relationships are emphasized, not necessarily in opposition but complementary to one another, consistent with how the Ancient Egyptians viewed the multiple facets of reality. He was most often depicted as a falcon, most likely a lanner falcon or peregrine falcon, or as a man with a falcon head.

The Ptolemaic Kingdom or Ptolemaic Empire was an Ancient Greek polity based in Egypt during the Hellenistic period. It was founded in 305 BC by the Macedonian general Ptolemy I Soter, a companion of Alexander the Great, and ruled by the Ptolemaic dynasty until the death of Cleopatra VII in 30 BC. Reigning for nearly three centuries, the Ptolemies were the longest and final dynasty of ancient Egypt, heralding a distinctly new era for religious and cultural syncretism between Greek and Egyptian culture.
