According to Merlin Stone, in Ancient Mirrors of Womanhood, Isis' name means "Ancient Ancient", and She was portrayed as a Creator figure in Her own right; She was said to be the star Sirius, whose tears created the waters of the Nile, for the nourishment of Her people.
Planting and agriculture, spinning and weaving of the flax plant, medicine, and law were all Isis' domains. Yet She was much loved on account of Her tender ferocity on behalf of the helpless, particularly of the dead. It was said that Isis' brother and husband, Osiris, was murdered by Seth, another brother. Osiris' remains were concealed and scattered throughout the land of Egypt. Isis journeyed through many trials and horrors, to recollect all the parts of Osiris' body, and through Her magic, was able to revive him, at least long enough for him to father a son to Her; She called him Horus.
Isis' popularity spread far beyond Egypt; there were temples to Isis in Rome, and then throughout the Roman Empire, including London.
