AN IMPORTANT MINING SURVEY OF THE PAPAL LANDS IN THE VICINITY OF ALUMIERE in the Tolfa mountains near Civitavecchia and Tolfa, 30 miles northwest of Rome, providing a detailed record of the alunite (alumstone) mines in the area. Alunite was first mined in the area of Tolfa in the 15th century, it occurs in volcanic rocks and from it alum can be extracted. Alum was an important coating for sizing papers or making cloth fibres more absorbent to dye, and was useful revenue for the Vatican. This detailed survey was made by Cingolani for Pope Innocent XII (Antonio Pignatelli, 1615-1700) and commissioned through the Treasurer-General of the Vatican, Cardinal Lorenzo Corsini (1652-1720, later Pope Clement XII), and was himself a great book and map collector. Pope Innocent XII was noted for his reforming zeal, and had ordained that no Pope should give offices, lands or revenues to any relative. This survey may have formed part of broader analysis of the economic potential of the Papal estates. Cinogolani is also known for a survey of the Campagna of Rome published in 6 sheets by Paluzzi in Rome, 1692, (Frutaz CCI).
