J.R.R. Tolkien’s original name for Gandalf in his mythology was Olórin.
Olórin was the Maia name of the being who later appeared in Middle-earth as Gandalf. In Valinor, he belonged to the Maiar, spiritual beings who served the Valar. Tolkien describes him as having learned pity and patience, qualities that help explain the wisdom and compassion associated with Gandalf.
Gandalf was not the character’s only name. In different places and languages he was called Mithrandir by the Elves, Tharkûn by the Dwarves, and Gandalf by Men. His name Olórin belongs to his earlier existence in the West, before he was sent to Middle-earth as one of the Istari.
The Istari were emissaries sent to resist Sauron without ruling the peoples of Middle-earth by force. Gandalf’s role therefore differs from that of a conventional warrior or king. His influence comes through counsel, courage, friendship, and the ability to inspire others to act.
