eradanmasculine name. eradan
I would suggest Man of Eru, Man of the One, or Man of God. Lonely man is possible, but nonsensical. Eradan had a wife, a son, and perhaps other children. He was the 2nd Steward of Gondor, and hardly alone or lonely. The Numenoreans, unlike the Eldar, worshiped Eru only. Thus, for the Numenoreans of Gondor, Eru would hold a special place. On Numenor, the summit of Meneltarma was "flattened and depressed, and could contain a great multitude". It was considered the most sacred place of Númenor as a shrine to Eru Ilúvatar; nothing was built there, and "no tool or weapon had ever been borne". Only the Kings were allowed to speak on the summit, when they said the Three Prayers to Ilúvatar; otherwise people were free to ascend the mountain, but none broke the silence in awe. The only animals to dwell there were the Eagles, believed by the Númenóreans to have been sent by Manwë to watch upon the hallow and the land. Before the coming of the Shadow, the Númenóreans maintained several traditions connected with the worship of Ilúvatar and respect to the Valar. Among them are recorded the setting a bough of oiolairë upon the prow of a departing ship, the ceremonies concerned with the passing of the Sceptre, and laying down one's life.
The most famous traditions were the Three Prayers, during which a great concourse of people ascended to the holy summit of Meneltarma and the King praised Eru Ilúvatar. These were:
Erukyermë, held at the beginning of spring, the prayer for a good year; Erulaitalë in the middle of summer, the prayer for a good harvest; Eruhantalë in the autumn, the thanksgiving for a good harvest.
