Isis
Isis was identified by the Greeks with Demeter, Hera, Selene (and even Aphrodite, because of a late confusion between Isis and Hathor). Isis started off as a modest Delta divinity but eventually absorbed the qualities of all other goddesses. She was more popular than any other goddess in the Egyptian pantheon and had a reputation as a great magickian. She was a universal goddess who took her place in the night sky as Sirius.
The cult of Isis spread from Egypt northwards to Phoenicia, Syria and Palestine; to Asia minor; to Cyprus, Rhodes, Crete, Samos and other islands in the Aegean; to many parts of mainland Greece including Corinth, Argos and Thessaly; to Malta and Sicily; and finally to Rome.
In the first century BCE, Isis was perhaps the most popular goddess in the Eternal City, from which her cult spread to the furthest reaches of the Roman Empire, including Britain, her only rival was Mithras.
The cult of Isis was eventually superseded by that of the Virgin Mary and the Baby Jesus, the iconography of which was borrowed from representations of Isis suckling Horus. [Fortunately, Isis continues to be revered in magickal circles.]
Isis learnt her magick from Thoth, and tricked Ra himself into revealing his magickal name to her, by which she acquired his full magickal knowledge. In ancient times, her magickal powers were extensively called upon for many uses including the healing of children. In late antiquity, Isis was used in divination, protection, and also in spells for fetching and love. Isis was the most widely worshipped goddess of late antiquity.
