Winter Comes to Nargothrond
I like to repost this poem when winter sets in (or else to email it to the cast of friends). It is, for my money, one of Tolkien's overlooked gems:
The summer slowly     in the sad forest
waned and faded.     In the west arose
winds that wandered     over warring seas.
Leaves were loosened     from labouring boughs:
fallow-gold they fell,     and the feet buried
of trees standing     tall and naked,
rustling restlessly     down roofless aisles,
shifting and drifting.
The shining vesel
of the sailing moon     with slender mast,
with shrouds shapen     of shimmering flame,
uprose ruddy     on the rim of Evening
by the misty wharves     on the margin of the world.
With winding horns     winter hunted
in the weeping woods,     wild and ruthless;
sleet came slashing,     and slanting hail
from glowering heaven     grey and sunless,
whistling whiplash     whirled by tempest.
The floods were freed     and fallow waters
sweeping seaward,     swollen, angry,
filled with flotsam,     foaming, turbid,
passed in tulmult.     The tempest died.
Frost descended     from far mountains
steel-cold and still.     Stony-glinting
icehung evening     was opened wide,
a dome of crystal     over deep silence,
over windless wastes     and woods standing
as frozen phantoms     under flickering stars.
