Is there any significance to the ring-bearers, who actually put the One Ring on, wearing the One Ring on their forefingers rather than on their ring fingers in the LOTR movies? Is this a stylistic choice just for the movies or did Tolkien specify the forefinger in the LOTR canon?
At first I thought it was because Sauron's finger was so much larger than a mere man's, but in Fellowship of the Ring the ring shrinks in Isildur's hand to become what appears to be an average size.
This may or may not be related, but I noticed that Aragorn wears his snake ring on his forefinger as well.
I wasn't able to find anything addressing the wearing of the One Ring at either the LOTR Wikia or The Tolkien Gateway.
