Set was said to be a friend of the dead, helping them to ascend to heaven on his ladder (maqet), and the crowner of pharaohs and leader of warriors. Set became the patron deity of soldiers, who often wore Set amulets made of bronze or faience, hoping to acquire Set’s strength and protection. The warrior-king Tuthmosis III called himself “Beloved of Set.” Set was thought to be the lord of metals – iron, the hardest metal known to the Egyptians, was called the “Bones of Set.” Set was invoked for fertility – he often appears on uterine amulets to either open or close the womb. Like Anubis, the worship of Set predates that of both Horus and Osiris.
