The Grand Tour and the Rise of the Vedute

The 18th century saw the flourishing of the veduta—detailed landscape paintings of Italian cities, particularly Rome, created as souvenirs for aristocratic travelers on the Grand Tour. Among the most celebrated was Giovanni Paolo Pannini’s The French Ambassador to the Holy See Leaving St. Peter’s Square, Rome (1757). While the foreground captures the opulence of ten lavishly decorated carriages, the true focal point is St. Peter’s Basilica, the grandest church in Christendom. Its dome, designed by Michelangelo; its façade, by Carlo Maderno; and its colonnades, by Gian Lorenzo Bernini—all combined to affirm the supreme authority of the pope as the successor of St. Peter and the spiritual leader of the Catholic world.

The painting immortalizes a moment of diplomatic ritual: Count de Stainville (later Duke of Choiseul), the French ambassador, descending the Scala Regia (Royal Staircase, another Bernini masterpiece) to meet the equestrian statue of Emperor Constantine, whose conversion to Christianity marked the faith’s imperial triumph. The ambassador then proceeded to the Sala Regia, where he knelt three times before the pope, even kissing his slipper—a gesture of deference to Christ’s earthly representative.

The Diplomatic Theater and the Erosion of Papal Influence

Yet behind this spectacle lay a deeper reality: the waning political power of the papacy. Stainville, though performing the rituals, was hardly a devout Catholic. His appointment in 1753 had scandalized Rome due to his libertine lifestyle and Enlightenment sympathies. By 1757, he was departing for Vienna—a promotion orchestrated by Madame de Pompadour, Louis XV’s influential mistress.

Upon his return to France as de facto prime minister, Stainville dealt a severe blow to the Church by persuading Louis XV to expel the Jesuits, the order most loyal to papal absolutism. This set the stage for the Jesuits’ suppression in 1773 under Pope Clement XIV—a humiliating capitulation to secular powers. The papacy, once capable of humbling emperors (as Gregory VII did at Canossa in 1077), now found itself powerless against monarchs like Napoleon, who imprisoned Pius VII in 1809.

The Illusion of Papal Infallibility

The gap between the papacy’s spiritual claims and its political weakness was stark. Though papal infallibility was not formally declared until 1870, the idea had circulated for centuries. By the 18th century, figures like St. Alfonso Liguori (1696–1787) championed the doctrine, yet it clashed with the era’s growing skepticism. The Renaissance popes’ excesses—nepotism, corruption, and lavish patronage—had already eroded the Church’s moral authority. Urban VIII (1623–1644) epitomized this decline, turning Rome into a Baroque spectacle while his family, the Barberini, amassed vast wealth. A contemporary satirist quipped:

“Urban did what’s fit for stone:
He fed his bees but starved his own.”

The Grand Tourists and the Critique of Rome

As Rome shifted from a pilgrimage site to a tourist destination, its flaws became more visible. Grand Tourists like Edward Gibbon, inspired by the contrast between ancient glory and Christian decay, penned scathing critiques. Horace Walpole lamented in 1740:

“I have seen Rome in its decline—neglected by ignorant and impoverished Romans, its villas crumbling, its paintings ruined by damp.”

Even Catholic rulers like Frederick the Great mocked the papacy. In his History of My Time, he derided the election of Pope Benedict XIV (Lambertini) with a fabricated anecdote about the Holy Spirit’s indecision.

The Secularization of Europe

The papacy’s decline mirrored broader trends. The Peace of Westphalia (1648) ignored papal objections, secularizing church lands and reducing Rome’s influence. By the 18th century, sovereign states—France, Spain, Austria—openly defied papal decrees. In 1768, when Pope Clement XIII condemned the Duke of Parma’s anti-clerical reforms, France occupied Avignon, Naples seized Benevento, and Spain backed the duke. As Choiseul sneered, “The pope is a fool, and his secretary an idiot.”

Yet the Church endured. Despite setbacks, Catholicism expanded globally, and the pope remained a spiritual leader for millions. As Stalin later scoffed, “How many divisions does the pope have?”—only to see the Church outlast the Soviet Union.

The Legacy of the Baroque Papacy

The 18th-century papacy, caught between Baroque splendor and Enlightenment critique, marked a turning point. The Grand Tour’s vedute immortalized its grandeur, but the era’s thinkers—Gibbon, Voltaire, Frederick the Great—exposed its fragility. The expulsion of the Jesuits and Napoleon’s captivity of Pius VII signaled the end of papal temporal power, yet the Church’s spiritual influence persisted.

In the twilight of the ancien régime, the papacy’s paradox was clear: it commanded reverence but lacked real power. The vedute—like Pannini’s masterpiece—captured this duality, preserving the illusion of supremacy even as the modern world moved on.
