Man behind the Mythology

[Fordim Hedgethistle]

All right, this is as tough a question as I am capable of. Which means it will probably take Esty all of 15 minutes to get it. *sigh*


What is the connection between the following poem and Tolkien's reputation as a writer?

Doom is dark and deeper than any sea-dingle.
Upon what man it fall
In spring, day-wishing flowers appearing,
Avalanche sliding, white snow from rock-face,
That he should leave his house,
No cloud-soft hand can hold him, restraint by women;
But ever that man goes
Through place-keepers, through forest trees,
A stranger to strangers over undried sea,
Houses for fishes, suffocating water,
Or lonely on fell as chat,
By pot-holed becks
A bird stone-haunting, an unquiet bird.

There head falls forward, fatigued at evening,
And dreams of home,
Waving from window, spread of welcome,
Kissing of wife under single sheet;
But waking sees
Bird-flocks nameless to him, through doorway voices
Of new men making another love.

Save him from hostile capture,
From sudden tiger's leap at corner;
Protect his house,
His anxious house where days are counted
From thunderbolt protect,
From gradual ruin spreading like a stain;
Converting number from vague to certain,
Bring joy, bring day of his returning,
Lucky with day approaching, with leaning dawn.
