La Topografia di Roma di Gio Batta Nolli Dalla Maggiore in Questa Minor Tavola Dal Medesimo Ridotta.

Description

This is the single-sheet reduction of Giambattista Nolli’s La Nuova Topografia di Roma, published by Ignazio Benedetti and based directly on the monumental twelve-sheet original of 1748. Its title, La Topografia di Roma di Gio Batta Nolli Dalla Maggiore in Questa Minor Tavola Dal Medesimo Ridotta, declares its origins plainly: the topography of Rome by Giambattista Nolli, reduced from the larger map into this smaller version by the same author.

What elevates the sheet from a mere condensation into a work of independent importance is the identity of the artist responsible for its decorative program: the architectural views along the lower margin were engraved by Giovanni Battista Piranesi, bringing together on a single sheet the two supreme graphic chroniclers of eighteenth-century Rome.

The Map in Detail

The map presents Rome within its ancient walls in a single composition, compressing the content of Nolli’s twelve sheets into a unified plan that retains the figure-ground logic and ichnographic precision of the original. The city’s street network, principal monuments, churches, and open spaces are all legible, with the characteristic contrast of black built fabric against white public space that made the larger map so revolutionary. An index panel on the left, headed Indice Delle Fabbriche più riguardevoli contenute nella Pianta, lists the principal buildings and monuments identifiable on the plan. A dedicatory cartouche, addressed to Cardinal Gio. Carlo Boschi occupies the upper left, attended by putti. On the right, a further index and a small vignette of one of Rome’s great columns supplement the map’s reference function.

The lower margin is dominated by a sweeping architectural capriccio engraved by Piranesi: on the left, St. Peter’s Square and Basilica seen in dramatic perspective; on the right, an assembly of ancient and Baroque Roman monuments, including ruins, fountains, and church façades, arranged with the theatrical grandeur characteristic of Piranesi’s vedute. Between them, the title is presented on a monumental stone plinth set in the foreground of the scene.

Historical Context

The twelve-sheet Nolli map of 1748 was a work of monumental scale and cost, accessible in its complete form only to the most well-resourced institutions and collectors. The single-sheet reduction answered a clear demand for a more portable and affordable version of the same authoritative survey, one that could serve the diplomat, the architect, the Grand Tour traveler, and the scholar who needed Nolli’s topography but not at twelve sheets of wall-filling scale. That Piranesi was engaged to supply the decorative elements is a measure of both his standing in Rome by this period and the ambitions of the publication.

Piranesi had arrived in Rome from Venice in the 1740s and was already producing the etchings of Roman ruins and architecture that would make him the most influential visual interpreter of the ancient city in European culture. His contribution to this sheet, the dramatic perspective views along the lower margin, is entirely characteristic of his method, using deep shadow, monumental scale, and dense architectural layering to evoke the weight of Rome’s history.

Publication History and Census

This map was published by Ignazio Benedetti in Rome, based on the cartography of Giambattista Nolli’s La Nuova Topografia di Roma of 1748. The decorative elements were engraved by Giovanni Battista Piranesi. The map represents a separately published reduction of the larger work intended for a broader and more portable market than the monumental original.
