During his period as a novice in the order, Balsamo learned chemistry as well as a series of spiritual rites. In 1764, when he was twenty one, he convinced Vincenzo Marano—a wealthy goldsmith—of the existence of a hidden treasure buried several hundred years previously at Mount Pellegrino. The young man's knowledge of the occult, Marano reasoned, would be valuable in preventing the duo from being attacked by magical creatures guarding the treasure. In preparation for the expedition to Mount Pellegrino, however, Balsamo requested seventy pieces of silver from Marano.
