Bernhard Schimmelpfennig (translated by James Sievert), The Papacy (ISBN0-231-07515-4), p. 220. Quote: "The next day, after Prignano had called upon them to do so, most of the cardinals came back to the palace and enthroned him. Prignano gave himself the name of Urban VI. The cardinals presented him with the customary petitions, and then took part in worship services being held not for the new pope but in celebration of Holy Week, before the new pontiff was crowned on Easter Sunday, April 18. The cardinals stayed at his court for the next three months, assisting him with liturgical functions. The curia that had remained in Rome likewise seemed to have acknowledged him."
