Quote from : The Lord of the Rings: The Fellowship of the Ring Movie

[holding the Ring out to Frodo after dropping it in the fire]
Gandalf: Hold out your hand, Frodo. It's quite cool.
[Drops the Ring into Frodo's palm]
Gandalf: What do you see? Can you see anything?
Frodo: Nothing. There's nothing.
[Gandalf sighs in relief]
Frodo: Wait... there are markings. It's some form of Elvish, I can't read it.
Gandalf: There are few who can. The language is the that of Mordor, which I will not utter here.
Frodo: Mordor?
Gandalf: In the common tongue it reads "One Ring to Rule Them All. One Ring to Find Them. One Ring to Bring Them All and In The Darkness Bind Them."
