While the familiar form of the rhyme was not printed until around 1805, when it appeared in "Original Ditties for the Nursery", it is possible that Byrom was drawing on an existing rhyme. The characters are perhaps best known from Lewis Carroll's "Through the Looking-Glass and what Alice Found There" (1871).
