Isis
'Isis (Greek version, Egyptian is Aset) is the goddess of motherhood and fertility in ancient Egypt. She is a life-death-rebirth deity (see Legend of Osiris and Isis), as well as one of the Ennead. Later, she acquired the goddess Sopdet.
Originally, she was a goddess of royalty (her hieroglyph includes the word for "throne"). Later still (During the period of Greek dominance), she was the patron goddess of sailors.
She was a close companion of Arensnuphis.
Isis was the daughter of Nuit, goddess of the sky, and Seb, god of earth. She married with Osiris, her brother and the father of her son Horus. Osiris was murdered by Seth but she reassembled his body (leading to her associated with the underworld and the funerary cult) and impregnated herself with his body and gave birth to Horus in Khemnis, a swamp. In addition to Horus, Isis was the mother of Min (alternatively, they were lovers).
Together with her sister Nephthys they can be seen on the sides of coffins in human form, their wings outstreched protecting the dead. The sisters also had magical powers.
Isis helped her husband, killed by Seth, to come back to live and take over the rule in the land of the dead.
Isis is often symbolised by a cow, or also a cow's head or horns (illustrating a connection with Hathor). In art, she was depicted with her son, Horus, a crown and a vulture, and sometimes as a kite (bird) flying above Osiris' body.
Alternatively, Isis was identified as the scorpion goddess Serq or Selk.
The cult of Isis rose to great prominence in the Hellenistic world throughout the last centuries BCE up until it was eventually banned by the Christians in the sixth century. Despite the Isis mystery cult's growing popularity, there is evidence to suggest that the Isis mysteries were not altogether welcomed by the ruling classes in Rome. Her rites were considered by the princeps Augustus to be of a "pornographic" nature and capable of destroying the Roman moral fibre. It is not surprising therefore that part of Augustus' programme for reconstruction after the fall of the Roman Republic was an attempt to infuse new life into the old gods of Rome. Tacitus writes that after Julius Caesar's assassination, a temple in honour of Isis had been decreed in a moment of weakness; Augustus suspended this, and tried to turn Romans back to the Roman gods who were closely associated with the state. Eventually, the Roman emperor Gaius abandoned the Augustan wariness towards Oriental cults, and it was in his reign that the Isiac festival was established in Rome. According to Josephus, Gaius himself donned female garb and took part in the mysteries he instituted, and Isis acquired in the Hellenistic age a "new rank as a leading goddess of the Mediterranean world."
