Horus Decapitating Isis in a Fit of Rage
In the heat of the 'Contendings of Horus and Seth,' Isis takes pity on her brother Set and releases him from a magical trap. This act of mercy enrages her son Horus, who responds by decapitating her in a divine fit of fury. The god Thoth subsequently restores her by replacing her head with that of a cow, a central moment in the mythological development of the goddess's iconography.
