The Geste of Beren and Lúthien

Then Beren looked in Lúthien's eyes
and saw a light of starry skies,
and thence was slowly drawn his gaze
to Melian's face. As from a maze
of wonder dumb he woke; his heart
the bonds of awe there burst apart
and filled with the fearless pride of old;
in his glance now gleamed and anger cold.
'My feet hath fate, O king,' he said,
'here over the mountains bleeding led,
and what I sought not I have found,
and love it is hath here me bound.
Thy dearest treasure I desire;
nor rocks nor steel nor Morgoth's fire
nor all the power of Elfinesse
shall keep that gem I would possess.
For fairer than are born to Men
A daughter hast thou, Lúthien.'
