Ladies, like variegated tulips show;
'Tis to their changes half their charms we owe;
Fine by defect, and delicately weak,
Their happy spots the nice admirer take,
'Twas thus Calypso once each heart alarmed,
Awed without virtue, without beauty charmed;
Her tongue bewitched as oddly as her eyes,
Less wit than mimic, more a wit than wise;
Strange graces still, and           flights she had,
Was just not ugly, and was just not mad;
Yet ne'er so sure our passion to create,
As when she touched the brink of all we hate.
