How much revenue did the College of Cardinals receive as a corporate financial organisation in the late fifteenth century? What was the share of individual cardinals from the corporate sources of the College?
These are questions to which as yet no answer has been given, though materials long known to historians of papal finance exist towards answering them. The most important of these records are the division registers of the College of Cardinals contained in the series of Vatican Cameral documents entitled ‘Obligationes et Solutiones.’ Only one such register (vol. 80 in the series) survives for the late fifteenth century, while a fuller number are extant for the earlier period, notably three under Eugenius IV forming a continuous series for the pontificate. These earlier volumes, some rather different in character, deserve closer study in themselves and will be used here merely for general comparisons.
While numerous sections of vol. 80 have been studied and printed the register has rarely been considered as a whole or for what its main original purpose was, namely to record the cardinals' shares in the service taxes.
