Villanelle for an Anniversary

I've always been far too fond of villanelles. Best make a category for it!

Heaney wrote this for the 350th anniversary of the founding of Harvard, I am told.

By Seamus Heaney

A spirit moved. John Harvard walked the yard,
The atom lay unsplit, the west unwon,
The books stood open and the gates unbarred.

The maps dreamt on like moondust. Nothing stirred.
The future was a verb in hibernation.
A spirit moved, John Harvard walked the yard.

Before the classic style, before the clapboard,
All through the small hours of an origin,
The books stood open and the gate unbarred.

Night passage of a migratory bird.
Wingflap. Gownflap. Like a homing pigeon
A spirit moved, John Harvard walked the yard.

Was that his soul (look) sped to its reward
By grace or works? A shooting star? An omen?
The books stood open and the gate unbarred.

Begin again where frosts and tests were hard.
Find yourself or founder. Here, imagine
A spirit moves, John Harvard walks the yard,
The books stand open and the gates unbarred.
