Alguém que tenha acesso aos livros pode fornecer a cotação exata. Mas em algum lugar nos apêndices há uma citação que diz algo assim: "Círdan, que podia enxergar mais profundamente do que qualquer outra pessoa na Terra Média", viu que Olorin (Gandalf) era o melhor portador do anel. Há também uma citação de Cirdan, algo como "pegue este anel, pois ele irá ajudá-lo em seus esforços".
Acho que devo guardar uma cópia dos livros no trabalho:)
Apêndice B (O Conto dos Anos), quarto parágrafo sob o título A Terceira Idade :
Throughout the Third Age the guardianship of the Three Rings was known only to those who possessed them. But at the end it became known that they had been held at first by the three greatest of the Eldar: Gil-Galad, Galadriel and Círdan. The ring of Gil-Galad was given by him to Elrond; but Círdan surrendered his to Mithrandir. For Círdan saw further and deeper than any other in Middle-earth, and he welcomed Mithrandir at the Grey Havens, knowing whence he came and whither he would return.
"Take this ring, Master," he said, "for your labours will be heavy**; but it will support you in the weariness that you have taken upon yourself. For this is the Ring of Fire, and with it you may rekindle hearts in a world that grows chill. But as for me, my heart is with the Sea, and I will dwell by the grey shores until the last ship sails. I will await you."
