This is a handsome and beautifully engraved chart of historic Portobello Bay, which was a Spanish transfer point for gold and silver coming from South America. It locates Forte Farnese on the point, the Governors Plantation, and presents the town in a simple block pattern. Adjacent to the town is the fortified Castello de la Gloria, and across the bay is the Castello de Todo Hierro and a few other buildings. The roads are well detailed including the Strada verso Panama, which extends off the map on its way to Panama City. In the ocean are a few rhumb lines and a fleur-de-lis. Drawn by Viol. Vanni and engraved by Giusep. Pazzi. This is a scarce Italian-produced map that appeared in Marco Corotellini's Gazzettiere Americano in 1763 and G. T. Masi Co.'s Atlante dell' America... in 1777, which is distinguished by its wider margins.
