Isis, Osiris and Seth are divine Egyptian triplets. Already in the womb, a special bond developed between Isis and her brother Osiris, much to Seth’s horror. As they grow older and Isis and Osiris begin a love affair, Seth flares up in jealousy and kills his brother. Seth cuts Osiris’ corpse into 14 pieces which he scatters in the Nile.
Desperately sad Isis sails across the river and finds all of Osiris’ body parts, except for his penis. With her own thumb she creates a male sex organ, managing thus to impregnate herself with their child, Horus.
