Alan Seeger - Coucy

The rooks aclamor when one enters here
Startle the empty towers far overhead;
Through gaping walls the summer fields appear,
Green, tan, or, poppy-mingled, tinged with red.
The courts where revel rang deep grass and moss
Cover, and tangled vines have overgrown
The gate where banners blazoned with a cross
Rolled forth to toss round Tyre and Ascalon.
Decay consumes it. The old causes fade.
And fretting for the contest many a heart
Waits their Tyrtaeus to chant on the new.
Oh, pass him by who, in this haunted shade
Musing enthralled, has only this much art,
To love the things the birds and flowers love too.

Alan Seeger
