#the lays of beleriand

He sped towards the hillock green,
the lissom limbs, the dancing sheen;
he leapt upon the grassy hill
his arms with loveliness to fill:
his arms were empty, and she fled;
away, away her white feet sped.
But as she went he swiftly came
and called her with the tender name
of nightingales in elvish tongue,
that all the woods now sudden rung:
‘Tinúviel! Tinúviel!’
And clear his voice was as a bell;
'Tinúviel! Tinúviel!’
His voice such love and longing filled
one moment stood she, fear was stilled;
one moment only; like a flame
he leaped towards her as she stayed
and caught and kissed that elfin maid.

As love there woke in sweet surprise
the starlight trembled in her eyes.
A! Lúthien! A! Lúthien!
more fair than any child of Men;
O! loveliest maid of Elfinesse,
what madness does thee now possess!
A! lissom limbs and shadowy hair
and chaplet of white snowdrops there;
O! starry diadem and white 
pale hands beneath the pale moonlight!
She left his arms and slipped away
just at the breaking of the day.
