‘Hold it up!’ said Gandalf. ‘And look closely!’
As Frodo did so, he now saw fine lines, finer than the finest penstrokes, running along the ring, outside and inside: lines of fire that seemed to form the letters of a flowing script. They shone piercingly bright, and yet remote, as if out of a great depth.
‘I cannot read the fiery letters,’ said Frodo in a quavering voice.
‘No,’ said Gandalf, ‘but I can. The letters are Elvish, of an ancient mode, but the language is that of Mordor, which I will not utter here. But this in the Common Tongue is what is said, close enough:
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them.
