   So an old Abbess for the rattling Rakes, / A tempting dish of human nature makes, / And dresses up a luscious Maid: / I rather should have said, indeed, undresses, / To please a youth's unsanctified caresses. 1793, John Wolcot, A Poetical, Serious, and Possibly Impertinent, Epistle to the Pope, Ode II, page 33
