La caída de Finrod Felagund

And it is told in the Lay of Leithian, which is the Release from Bondage, that when the company of Beren and Finrod Felagund passed Tol Sirion (which Finrod himself had built), their disguise was challenged by Sauron, the master of the tower. And before the gates of the tower was a great contest for the mastery, between Finrod Felagund King of Nargothrond, and Sauron Gorthaur the Vassal of Morgoth. The Lay of Leithian reads...

He chanted a song of wizardry,
Of piercing, opening, of treachery,
Revealing, uncovering, betraying,

Then sudden Felagund there swaying,
Sang in answer a song of staying,
Resisting, battling, against power,
Of secrets kept, strength like a tower,

Of trust unbroken, freedom, escape,
Of changing and of shifting shape,

Of snares eluded, broken traps,
The prison opening, the chain that snaps.

Backwards and forwards swayed their song,
Reeling and foundering as ever more strong,
The chanting swelled and Felagund fought,
And all the magic and might he brought,
Of Elvenesse into his words,

Then in the gloom they heard the birds,
Singing afar in Nargothrond,
The sighing of the Sea beyond,
Upon the western shores on sand,
On sand of pearls in Elven-land.

Then the gloom gathered, darkness growing,
In Valinor the red blood flowing,
Beside the Sea where the Noldor slew,
The Foamriders, and stealing drew,
Their white ships with their white sails,
From lamp-lit havens, the wind wails,

The wolf howls, the ravens flee,
The ice mutters in the mouths of the Sea,

The captives sad in Angband mourn,
Thunder rumbles, the fires burn,
And Finrod fell before the throne.
