The Sistine Chapel: History, art and papal conclaves

Beneath the vibrant colours and celestial figures of Michelangelo's masterpiece, where whispered prayers and political intrigues have influenced the course of history, lies the Sistine Chapel.

This architectural marvel is more than a Renaissance work of art; it is a silent witness to papal power, the Catholic faith, and the centuries-old tradition of papal conclave.

The Sistine Chapel will again capture global attention in the coming weeks as the Catholic Church prepares for a conclave following Pope Francis's passing on Easter Monday.

In today's newsletter, we'll explore its origins in the 15th century and its transformation into the sacred venue of Papal Conclaves.

Commissioned by Pope Sixtus IV from 1475 to 1481, the Sistine Chapel, designed by Giovanni dei Dolci, was built to replace the deteriorating Cappella Magna. The Papal States were dealing with internal conflict and the external threat of the Ottoman Empire, which had taken Constantinople.

Like all governments, the church initiated a grand project as a symbol of papal authority. Moreover, Pope Sixtus IV was a patron of the Italian Renaissance. He promoted art to showcase the Church's power and give it a divine connection.

He recruited leading Renaissance painters like Botticelli, Perugino and Ghirlandaio to adorn its walls with frescoes that blended biblical narratives with the era's intellectual fervour. Decades after Pope Sixtus IV, Pope Julius II elevated the chapel's legacy by commissioning Michaelangelo to paint the iconic ceiling from 1508 to 1512.

The Last Judgement fresco painted for Pope Paul III between 1536 and 1541 is one of the great achievements of Western painting.

The artistic masterpiece

While the Renaissance brought a surge in intellectual activity, literacy was still largely confined to the elites. Everyone else, especially in rural areas, relied on oral traditions and visual storytelling for information and education.

Recognizing this, the church often commissioned grand works of art to convey biblical stories and theological concepts. Frescoes, sculptures, and stained glass served as visual narratives, making complex religious ideas accessible to all.

The Sistine Chapel is a fantastic example of how art was used to inspire faith and teach doctrine in the 15th century. For instance, The Temptations of Christ fresco by Sandro Botticelli depicts three key episodes from the Gospels: Jesus being tempted by the Devil to turn stones into bread, to throw Himself from the temple, and to worship the Devil in exchange for worldly power.

These scenes are arranged in a single fresco, with each episode occupying a distinct section, yet harmoniously integrated into the overall composition

Michaelangelo's Last Judgement is another excellent example. Painted between 1536 and 1541, the fresco is a monumental depiction of the Second Coming of Christ and the final judgement of souls. It showcases Christ as a powerful and commanding figure, surrounded by saints. The saved ascend to Heaven on Christ's right, while the damned are dragged to Hell on His left. The fresco is filled with emotional intensity, with figures expressing awe, fear, and despair.

Beyond theology, these artworks highlight the blending of Renaissance humanism ideals with Christian theology. The Creation of Adam, painted by Michaelangelo between 1511 and 1512, is a great example; the hand gesture symbolises the divine spark, while its anatomical accuracy highlights humanist ideals.

Flanking the ceiling are portraits of prophets and sibyls - pagan prophetesses who, according to Christian tradition, prophesied the coming of Jesus - by Michaelangelo. These paintings confer the universality of divine truth. The fusion of pagan and Old Testament prophets reflected the renewed interest in classical Greek philosophy and early Christianity during the Renaissance.

Architectural symbolism

The chapel's design - a fortified, rectangular space that mimics Solomon's Temple in Jerusalem - symbolised spiritual continuity and papal power. The chapel is approximately three times as long as it is wide, and its height is about half of its length, reflecting the traditional proportions of Solomon's Temple.

Moreover, the harmoniuos proportion of its architectural design embodies Renaissance aesthetics of balance, order and grandeur. For instance, the vaulted ceiling, arches and pilasters were inspired by Roman design. Similarly, the chapel's interiors follow precise mathematical ratios typical of Renaissance architecture and the revival of classical antiquity.

The shallow cross vault ceiling, intersected by smaller vaults and pilasters create a rythmic architectural framework that complements the extensive fresco decoration. This integration of architecture and painting exemplifies Renaissance ideals of uniting multiple art forms to create a cohesive narrative.

Michaelangelo’s ceiling frescoes, featuring anatomical precision, classical themes, and dynamic human figures, also demostrate Renaissance artistic styles, blending Christian theology with humanistic ideals.

While the Sistine Chapel's design reflects it role as a sacred venue for papal conclaves, Pope Sixtus IV also visualized it as a political statement: a grand stage for papal ceremonies and diplomatic events to showcase the Church's power and cultural influence.

Consider how its architectural design is modelled on Solomon's Temple. It symbolically links papal power to bibilical tradition, emphasizing the divine origin of the pope's authority. Furthermore, Michaelangelo's frescoes visually assert the pope's authority by establishing a direct line of papal succession from the apostles - the traditional heirs of Christ's power - to Peter and the popes.

This connection legitimized the pope's spiritual and political supremacy during a time of internal and external conflict.

The papal conclaves

The Sistine Chapel hosted the first papal conclave in 1492 during the election that made Rodrigo Borgia Pope Alexander VI. Historically, conclaves were held in various locations - like the Dominican convent of Santa Maria sopra Minerva - influenced by political instability or practical concerns.

Built as the Cappella Maggiore by Pope Sixtus IV, the Sistine Chapel became central to papal religious life. Thus, its central location within the Apostolic Palace and its symbolic connection to papal authority made it an attractive site for conclaves.

Furthermore, its sacred status and richly decorated interiors provided a solemn and spiritually charged environment for electing a new pope. Its enclosed architecture also allowed for the necessary secrecy and security during the conclave.

However, challenges like poor hygeiene and health risks due to the strict enclosure of the cardinals during the conclave did not make the Sistine Chapel the permanent site for conclaves until 1878. This led to various functional adaptations to the structure for conclave rituals.

They include the installation of a chimney on the roof to emit the iconic black and white smoke signals and temporary wooden flooring and ramps to protect the chapel's marble floor. Moreover, the cardinals traditionally stayed in small, sparsely furnished rooms located within the Apolistic Palace, close to the chapel.

It was only in 1996 that Pope John Paul II established the Domus Sanctae Marthae, a hotel-like residence within the Vatican where cardinals now stay during conclaves.

The Sistine Chapel today 

While the chapel remains a sacred space for important religious ceremonies like the impending papal conclave, it also hosts other significant liturgical celebrations, especially during major moments in the catholic calender like Easter and Chrismas.

Moreover, it is a major tourist destination, attracting around 20,000 visitors daily during its peak season. Tourists primarily come to admire Michaelangelo's masterpieces and frescoes by leading Renaissance artists.

However, the high number of visitors poses challenges such as crowding, noise, and humidity which affect visitor experience and preservation efforts. To protect the artwork, Vatican officials have contemplated limiting visitor numbers and have prohibited photography inside the chapel.
