osiris

The goddess Isis, along with Osiris, is probably one of the best known deities from ancient Egypt. The couple are synonymous with the seemingly mysterious, often-confusing religion. First attested in funerary texts from the pyramid of Unas (c. 2360 BC), Isis was the longest lived of the Egyptian pantheon. Her cult became dominant in the Greco-Roman period, with the goddess soaking up aspects of other goddesses including Hathor and Astarte until she became the ultimate, all-powerful deity. The last, and arguably most famous pharaoh, Cleopatra VII, often depicted herself as Isis.

Because her cult was adopted in Rome, it spread far outside of Egypt, sanctuaries being founded even as far north as London. Her temple at Philae was the last temple to close in Egypt in the 6th century AD after Christianity spread across the Roman Empire.
