THE PUBLIC REVENUE
Cruzada, although this was apparently an institution of the Church, were gathered into the royal treasury. The Cruzada mentioned here as a source of revenue was a bull published every two years which carried absolution from past offences and contained certain privileges with respect to the future. By purchasing it one might obtain ecclesiastical permission to eat certain kinds of food during Lent that were not ordinarily allowed on meagre days. The prices paid for the bulls ranged from a few cents to several dollars.
