Besides the sermons, some of the rhymed letters that John Ball sent about the country have been preserved:
"John Ball, Priest of St. Mary's, greets well all manner of men, and bids them in the name of the Trinity, Father, Son and Holy Ghost, to stand together manfully in truth. Help truth and truth shall help you.
"John Ball greeteth you all,
And doth to understand he hath rung your bell.
Now with right and might, will and skill,
God speed every dell.
John the Miller asketh help to turn his mill right:
He hath ground small, small:
The King's Son of Heaven will pay for it all.
Look thy mill go right, with its four sails dight.
