A French poem, similar to “Thirty days hath September”, numbering the days of the month, was recorded in the 13th century. From the later Middle Ages there are records of short children’s rhyming songs, often as marginalia. From the mid-16th century they begin to be recorded in English plays. “Pat-a-cake, pat-a-cake, baker’s man” is one of the oldest surviving English nursery rhymes. The earliest recorded version of the rhyme appears in Thomas d’Urfey’s play The Campaigners from 1698. Most nursery rhymes were not written down until the 18th century, when the publishing of children’s books began to move from polemic and education towards entertainment, but there is evidence for many rhymes existing before this, including “To market, to market” and “Cock a doodle doo”, which date from at least the late 16th century. Nursery rhymes with 17th century origins include, “Jack Sprat” (1639), “The Grand Old Duke of York” (1642), “Lavender’s Blue” (1672) and “Rain Rain Go Away” (1687).
