John Garth gave a talk at Marquette University today in connection with the Tolkien manuscript exhibit. I listened in via Zoom.
At one point he quoted from The Lord of the Rings, Gandalf musing how he'd like to be able to wrest a palantír to his control, "to look across the wide seas of water and of time to Tirion the Fair, and perceive the unimaginable hand and mind of Fëanor at their work." (Doing what? Creating the palantíri, among other things.)
And John said how much he'd like to be able to perceive the unimaginable hand and mind of Tolkien at their work - creating The Lord of the Rings and The Silmarillion, among other things.
