Isis was a goddess in Ancient Egyptian religious beliefs, whose worship spread throughout the Greco-Roman world. She was worshiped as the ideal mother, wife, matron of nature and magic. She was the friend of slaves, sinners, artisans, the downtrodden, as well as listening to the prayers of the wealthy, maidens, aristocrats and rulers. Isis is the Goddess of motherhood and fertility.
Shortly after 2,500 B.C., during the fifth dynasty, the first written records concerning the worship of Isis appear. The goddess Isis (the mother of Horus) was the first daughter of Geb, god of the Earth, and Nut, the goddess of the Overarching Sky, and was born on the fourth intercalary day. At some time Isis absorbed some characteristics of Hathor a powerful deity. In later myths about Isis, she had a brother, Osiris, who became her husband, and she then was said to have conceived Horus. Isis was instrumental in the resurrection of Osiris when he was murdered by Seth. Her magical skills restored his body to life after she gathered the body parts that had been strewn about the earth by Seth. This myth became very important in later Egyptian religious beliefs.
Isis is also known as the goddess of simplicity, from whom all beginnings arose, and was the Lady of bread, of beer, and of green fields. In later myths, Ancient Egyptians believed that the Nile River flooded every year because of her tears of sorrow for her dead husband, Osiris. This occurrence of his death and rebirth was relived each year through rituals. The worship of Isis eventually spread throughout the Greco-Roman world, continuing until the suppression of paganism in the Christian era.
