From The GOLDEN LEGEND or LIVES of the SAINTS
Compiled by Jacobus de Voragine, Archbishop of Genoa, 1275
This Henry put out of his court all the jongleurs, and gave to poor men all that was wont to be given to minstrels. In that time was so great discord in the church that there were three chosen to be pope, and a priest named Gratian gave to the others much money, and they left the See to him and he was pope.
