IV.3

Did not the heavenly rhetoric of thine eye, 
'Gainst whom the world cannot hold argument, 
Persuade my heart to this false perjury?
Vows for thee broke deserve not punishment. 
A woman I forswore; but I will prove,
Thou being a goddess, I forswore not thee: 
My vow was earthly, thou a heavenly love;
Thy grace being gain'd cures all disgrace in me. 
Vows are but breath, and breath a vapour is:  
Then thou, fair sun, which on my earth dost shine, 
Exhalest this vapour-vow; in thee it is:
If broken then, it is no fault of mine:
If by me broke, what fool is not so wise 
To lose an oath to win a paradise?
