Gondolin: Hidden City of the Elves

 Thither Tuor son of Fengel came out of the dim land
that the Gnomes have called Dor-Lómin, with Bronweg at his hand,
who fled from the Iron Mountains and had broken Melko’s chain
and cast his yoke of evil, of torment and bitter pain;
who alone most faithful-hearted led Tuor by long ways
through empty hills and valleys by dark nights and perilous days,
till his blue lamp magic-kindled, where flow the shadowy rills
beneath enchanted alders, found that Gate beneath the hills,
the door in dark Dungorthin that only the Gnome-folk knew.

how the Gods in council gathered on the outmost rocky bars
of the Lonely Island westward, and devised a land of ease
beyond the great sea-shadows and the shadowy seas;
how they made the deep gulf of Faerie with long and lonely shore . . .
