Can wash the balm off from an anointed king;
The breath of worldly men cannot depose
The deputy elected by the Lord.”

“Sweet smiling village, loveliest of the lawn,
Thy sports are fled and all thy charms withdrawn;
Amidst thy bowers the tyrant’s hand is seen,
And desolation saddens all thy green;
One only master grasps the whole domain,
And half a tillage stints thy smiling plain;”
—Oliver Goldsmith (1730?–1774)
