Italy - /Ponza // Grottone, // Gaviotta; Tommaso Santarelli - Piano del Porto di Ponza “PIANO del Porto DI PONZA (MONTEA) Isola a P. di Napoli. Gli scandagli sono - 1861-1880

A rare 19th-century nautical chart engraved by Saverio Santolini, active in Rome in the first half of the 19th century and known for his high-precision cartographic plates, portolans, and topographical charts. The signature is clearly legible at the bottom left: "Tav. S. Santolini in Roma."

The plate represents the "Port Plan of Ponza (Mountain)", with an accurate survey of the coasts, promontories, and hills using chiaroscuro hatching, according to the Italian technical tradition of the time. It shows the main port structures, including the pier, the fort, the urbanized areas, and the surrounding islets.

The grid of numbered backgrounds immediately identifies the document's nautical purpose: a chart intended for coastal navigation and safe entry into the port of Ponza. The Neapolitan scale, typical of the Bourbon period, is also present, although the engraving was made in Rome.

The card shows:
– the port of Ponza with the pier and the urban area
– the raised fort to protect the basin
– detection of the coasts through dense hatching
– numbered seabeds for navigation
– Smaller islands, including I. di Gaviotta (ancient toponym)
– route directions with bearing lines

Good.
