I have read a lot of Shakespeare over the years but I have never heard of a poem by Shakespeare titled "Spring." I note that nobody has tried to answer this question since it was posted on October 16, 2011. I suspect this is because nobody can identify such a poem. If there were such a poem by Shakespeare, I would guess that the theme of "Spring" would be the beauty, the delights of spring and how a young man's fancy turns to thoughts of love. Could you please clarify?
