The Three Prayers were the prayers of the Númenoreans to Eru. Three times a year, the Númenorean King would lead his people to the summit of Meneltarma, where they would engage in a ritual prayer. The Three Prayers took place at the beginning of spring, the height of mid-summer, and the end of autumn, and were known as the Erukyrmë, Erulaitalë, and Eruhantalë, respectively. It was tradition for the three Great Eagles, known as the Witnesses of Manwë, would hover over the King and his people during each of the Three Prayers.
While the Three Prayers were consistently observed by the early Kings of Númenor, the ritual soon fell into disuse as the party of the King’s Men established power. The first King who was said to have altogether abandoned the Prayers was Ar-Gimilzôr, the twenty-third ruler of Númenor.
