In the Bulla aurea ("Golden Bull") of 1479, Pope Sixtus IV granted indulgences to all who made donations to the Franciscan Order and to the Poor Clares, all visitors to Franciscan churches, and all who contributed money or work to the maintenance of Franciscan monasteries. The papal bull also granted special privileges to Franciscans who were appointed as inquisitors.
