Analysis of To winter in the Midst of his Reign

Thou grim physician, armed with septic shears,
Thou that dissemblest even in death's repose
Earth's quiet pulse and her remedial throes,
How dull thy visage on this day appears!
Let now the dismal heaven give vent, its tears
Come frozen ever; no gale coeval blows
Filled with the ravaged perfume of the rose;
And keep not all fair things forsaken biers?
O haste, then, spiritless minister, thy pains
To charge the sources of the unfruitful earth
For harvests blest in wood, in plot and lawn!
O laggard, on! till fire re-flood the veins
Of Spring here, ay, to trip the vales with Mirth,
As, long night over, does the exulting dawn!
