Charles III visiting Saint Peter's Basilica, Rome by Giovanni Paolo Pannini: among history and the view of Rome

Giovanni Paolo Pannini, a leading interpreter of the Roman veduta in the eighteenth century, painted Charles III Visiting St. Peter’s Basilica in 1746, an artwork that embodies the sense of magnificence and power celebrated in papal Rome. Today housed in the Museo Nazionale di Capodimonte, the painting depicts the triumphant entrance of King Charles III of Spain before the monumental façade of St. Peter’s, accompanied by his court and welcomed by the enthusiasm of a multitude eager to immortalize a major diplomatic event.

The sovereign appears as the central figure, portrayed on horseback and surrounded by the leading representatives of the Spanish state, while Roman society is reflected in the various types of onlookers, distinguished by their roles and attire. The artist, who was a direct witness of the visit, infuses the work with a solemn and celebratory energy, with the vibrant dynamism of the crowds and the classical stage-setting of the Vatican framing the political and cultural narrative. The fabric of the city thus intertwines with personal history, conveying a powerful message of alliance among the kingdoms of Europe.

Style
The style of Pannini’s painting is rooted in the Roman Baroque, enriched by a refined exploration of perspective and a meticulous attention to architectural detail. The artist, distinguished within the tradition of the vedutisti, constructs the scene with a precise orchestration of space and a realism that lends both veracity and narrative power.

The Baroque imprint is evident in the theatrical effect of the composition, in the movement of the figures, in the diffused luminosity, and in the inclusion of rich ornamental details that describe the splendor of the court and the glory of the papacy. Pannini draws inspiration from the perspectival innovations of contemporaries such as Canaletto, yet maintains his own artistic personality, choosing also to exalt the protagonists of the action.

Color and lighting
The handling of color in the work is masterful and rich. The palette favors warm and precious tones, with variations of red in the garments, gold and ochre in the architecture, and luminous whites to highlight ecclesiastical and regal details. Chiaroscuro, achieved through a careful distribution of light, contributes to creating evocative atmospheric effects, with sunlit zones and deep shadows that amplify the monumentality of the basilica.

Light, filtered through the architectural structures, accentuates the principal figures, immersing the viewer in a vibrant and solemn atmosphere, while the contrast between illuminated surfaces and shaded areas reinforces the sense of depth.

Spatial organization
In the painting, spatial depth is achieved through a stratified and rigorous perspective. The colonnades of St. Peter’s and the succession of architectural elements lead the gaze toward the background, where the papal buildings are depicted with a deliberately illusory blur. The figures, positioned at varying scales and distances, broaden the perception of space, guiding the viewer’s eye from the foreground ranks of the royal court to the more distant areas of the piazza.

The placement of the onlookers, progressively diminishing in scale, creates an effective and natural three-dimensionality, in which the monumentality of the setting dominates human presence. Architectural references such as the colonnade and the central portal provide a solid structure to the composition and help maintain visual order even within such a crowded scene.

Composition and framing
The balance of the composition reveals Pannini’s Baroque mastery in his pursuit of monumentality and in his orchestration of visual emotion. The central placement of Charles III on horseback accentuates the narrative dimension and lends a regal sense of pomp to the entry into St. Peter’s. Through a panoramic vision that embraces both the architectural setting and the multitude of participants, the painting leads the eye from the procession to the heart of the basilica, yielding a scene that is both harmonious and dynamic.

The dialogue between figures and monuments is continuous, allowing the urban landscape to become a living, vibrant stage where historical, political, and social interests converge in the visual experience. Pannini emphasizes a never-static sense of collectivity, where the movement of people and horses evokes the solemn bustle of great papal celebrations.

Technique and materials
The chosen support is canvas, upon which Pannini skillfully applies oil paint, a technique that allows for the rendering of tactile, detailed, and luminous surfaces. The pigments employed—from cardinal reds to golden yellows and brilliant whites—interact with the space to enhance both the sumptuousness of the garments and the monumental stone of the basilica.

The careful application of color and the use of brushes of varying sizes make it possible to achieve soft glazes and incisive detail, while the large-scale composition offers the artist the opportunity to orchestrate a sweeping and vibrant pictorial narrative. The textural effect heightens the physical presence of the protagonists and the monumentality of the architecture, producing a visual ensemble that is both moving and engaging. The painting, fluid and vibrant, conveys a sense of direct participation, allowing the viewer to relive the splendor and exceptionality of the king’s visit to eighteenth-century Rome.
