Thou silent power, whose welcome sway charms every anxious thought away; in whose divine oblivion drown'd, sore pain and weary toil grow mild, love is with kinder looks beguiled, and Grief forgets her fondly cherish'd wound; oh, whither hast thou flown, indulgent god? God of kind shadows and of healing dews, whom dost thou touch with thy Lethaean rod? Around whose temples now thy opiate airs diffuse?
