Go and catch a falling star , Get with child a mandrake root , Tell me where all past years are , Or who cleft the devil’s foot , Teach me to hear mermaids singing , Or to keep off envy’s stinging , And find What wind Serves to advance an honest mind . If thou be’st born to strange sights , Things invisible to see , Ride ten thousand days and nights , Till age snow white hairs on thee , Thou , when thou return’st , wilt tell me , All strange wonders that befell thee , And swear No where Lives a woman true , and fair . If thou find’st one , let me know , Such a pilgrimage were sweet ; Yet do not , I would not go , Though at next door we might meet, Though she were true , when you met her , And last , till you write your letter , Yet she Will be False , ere I come , to two , or three .
