From Tolkien Gateway

Silmo, an Ainu only appearing in the earliest versions of the legendarium, was appointed guardian of the tree Silpion — to be "ever mindful" of the watering of the tree. For this task, he was chosen by the Vala Lórien, who loved the youthful Silmo.[1]

He wanted to steer the Moon but could not do it and so Manwë appointed Ilinsor.[2]

Christopher Tolkien has suggested that the Maia Tilion (a later creation) "perhaps owes something to the figure of Silmo".[3]


Silmo is a Qenya name. His name in Gnomish was Thilim (containing the masculine ending -im).[4]
