In Egyptian lore, the children of Isis and Osiris are Horus and sometimes Set, depending on different interpretations of the mythology. Horus, often depicted as a falcon or a man with a falcon’s head, represents the sky and kingship. His birth was significant as it marked the continuation of Osiris's lineage and the ongoing struggle against chaos, personified by Set. The mythology surrounding their family emphasizes themes of heritage, power, and the legitimacy of rule.
