The Silmarillion, “Of Beren and Lúthien”. Sung by Beren when he, convinced of his imminent death, wanted to say farewell to his beloved Lúthien forever rather than risk her life too in the hopeless hunt for the Silmaril he had sworn to bring her father Thingol to be allowed to marry her.

Farewell sweet earth and northern sky,
for ever blest, since here did lie
and here with lissom limbs did run
beneath the Moon, beneath the Sun,
Lúthien Tinúviel
more fair than mortal tongue can tell.
Though all to ruin fell the world
and were dissolved and backward hurled
unmade into the old abyss,
yet were its making good, for this –
the dusk, the dawn, the earth, the sea –
that Lúthien for a time should be.
