Copper line engraving, period hand-painted in watercolour, 468x596 mm. Rare map from ‘L'Orbe Cattolico ossia Atlante Geografico Storico Ecclesiastico. Opera del Commendatore Girolamo Petri Officiale minutante della segreteria di Stato’. The map shows the various dioceses in bright and different colours, making the ecclesiastical divisions explicit. The Atlas was published only for the use of cardinals and high prelates in a limited number of copies, and is therefore of great rarity. In perfect condition, trace of central editorial crease with very slight, almost imperceptible yellowing of the paper.
