Hmm. There's a rite of prayer by the Kings of Númenor on the summit of the Meneltarma, the mountain in the centre of the island:
There no tool or weapon had ever been borne; and there none might
speak any word, save the King only. Thrice only in each year the King spoke, offering prayer for the
coming year at the Erukyermë in the first days of spring, praise of Eru Ilúvatar at the Erulaitalë in
midsummer, and thanksgiving to him at the Eruhantalë at the end of autumn.
