Poem to a Roman Female

My vision was more obscure in this poem. I wasn't sure to who I wished it to be addressed. However, the text supports the conclusion that it is to a Roman female (possibly divine). 

Sweet angel of light, be mine one last time,

great goddess of goodness, hear my rugged rhyme, 

Now or never, I do not wish to be alone, 

Yours, is the loveliest sight that I have ever known.  

Oh, Mercury, deliver this message unto her person, 

that she is the most beautiful of the lower heavens.
