Isis is a goddess in Egyptian mythology. She was most prominent mythologically as the wife of Osiris and mother of Horus, and was worshipped as the archetypical wife and mother. Her name literally means (female) of throne, i.e. Queen of the throne, which was portrayed by the emblem worn on her head, that of a throne. However, the hieroglyph of her name originally meant (female) of flesh, i.e. mortal, and she may simply have represented deified, historical queens. Her origins are uncertain but are believed to have come from the Nile Delta; however, unlike other Egyptian deities, she did not have a centralised cult at any point throughout her worship. First mentions of Isis date back to the Fifth dynasty of Egypt which is when the first literary inscriptions are found, but her cult became prominent late in Egyptian history, when it began to absorb the cults of many other goddesses. It eventually spread outside Egypt throughout the Middle East and Europe, with temples dedicated to her built as far away as the British Isles. Pockets of her worship remained in Christian Europe as late as the 6th century.
