I did, I did! IIRC, as Isildur holds Sauron's finger on his palm, the finger turns to ash and blows away, and then the ring shrinks down to human-sized.
Aragorn is wearing a ring on his index finger.
If I remember the earlier discussion of that ring correctly, it's supposed to be the Ring of Barahir. Barahir was the father of Beren; the ring was given to him by the Elf king Finrod Felagund as a token of friendship (back in the First Age, natch.) The ring was passed down through the descendents of Beren and Luthien to the Kings of Numenor, and was one of the relics brought out of the destruction of Numenor by Elendil and his sons.
A late good morning. I slept in until almost 9, then went on errands and chores. So now I have a three hour window until work - but I'll probably be on late again. It's too fun!
