The king ordered one of his daughters to copulate with the fungus. Ignoring the request, the perfidious daughter sent one of her servants in her place. Twin boys were born from this union. Learning about his daughter's duplicity, the monarch ordered the death of the twins. To save her children, the servant entrusted the boys to a shepherd, who abandoned them by the river. A wolf found them and fed them. The twins were Romulus and Remus, the founders of Rome.
Apparently the obelisk in St.Peter's Square in the Vatican stands exactly on the spot where the miraculous phallus appeared.
