Nursery Rhyme. V. Historical

[The following perhaps refers to Joanna of Castile, who visited the court of Henry the Seventh, in the year 1506.]
I had a little nut tree, nothing would it bear
But a silver nutmeg and a golden pear;
The king of Spain's daughter came to visit me,
And all was because of my little nut tree.
I skipp'd over water, I danced over sea,
And all the birds in the air couldn't catch me.
