Pope Francis's legacy and Pope Leo's future, reflected in the inclusive frescoes of the Sistine Chapel - ABC Religion & Ethics
The college of cardinals who elected him represent dioceses from Asia, Oceania, Africa, the Middle East, Europe and the Americas — a truly global conclave. Such global representation and the expedience of the decision to appoint this uniquely global citizen sends the world a subtle message: that Pope Francis's legacy will live on .

A significant aspect of this legacy was Francis's promotion of inter-faith dialogue and an inclusive vision of the Church — seeking the inspiration of the Holy Spirit from the peripheries. Many might be surprised to learn that Michelangelo's frescoes, under which the cardinals made their decision, contain similar themes, reflecting central tenets of Renaissance theology.

The dizzying scale and complexity of Michelangelo's composition is awe inspiring, and perhaps, a little overwhelming. His elaborate painted architecture was a groundbreaking masterpiece in its own right. Some have compared its structure with Rome's triumphal Arch of Constantine, through which conquering generals would lead their legions, bestowing glory on their return from successful military campaigns. Others have described it as an ancient temenos , a designated space where priests would watch for auspices in antiquity.
Perched on stone thrones at the precipice of his painted architecture, and flanking his central scenes on all sides, are a collection of towering figures testifying to Michelangelo's spectacular mastery of gestural variance — these are the Hebrew prophets and pagan sibyls.

Mirroring the cosmopolitan composition of the current college of cardinals, Michelangelo's Sistine sibyls include the Libyan and Erythraean from Africa, the Delphic (Greek) and Cumaean (Roman) from Europe, and the Persian (Iranian) from West Asia.
During the Italian Renaissance, sibyls were often understood to represent the three continents of the known world at the time: Africa, Asia and Europe. Michelangelo's tutor, Ghirlandaio, was among the first to include depictions of sibyls in a Catholic chapel in the 1480s, in Santa Trinita in Florence. At the same time, the clergy of Siena Cathedral were introduced to a prominent depiction of Hermes Trismegistus accompanied by ten sibyls on the mosaic pavement, which Michelangelo would have seen when he was visiting the duomo ahead of his commission for the Piccolomini altar. Aby Warburg called these appearances a 'secular incursion' in Catholic art, which reflected a contemporary exploration of interfaith dialogue and promotion of religious universalism during the Renaissance.

Nicholas of Cusa (1401–1464), cardinal, theologian and Vicar of Rome, provides a great example of this. He published On the Peace of Faith in 1453, the year Constantinople fell to the Ottomans. In it he described the universality of religion and discussed the need for interfaith dialogue:
You are all in agreement, therefore, that there is one sole worship of God, which all of you presuppose in your various rites … It would be possible, through the experience of a few wise men who are well acquainted with all the diverse practices which are observed in religions across the world, to find a unique and propitious concordance.
Marsilio Ficino (1433–1499), a priest, translator, musician, astrologer, doctor and prominent Renaissance theologian-philosopher, spoke of the universal religious impulse in his On the Christian Religion : 'The human soul, by its very nature, is inclined toward the divine, and this inclination is the root of all religion.' Returning to this theme again, later in his work, Ficino wrote: 'All religions, though they differ in their rites and names, are directed toward the one God, who is the source of all truth.'
Alongside themes of interfaith dialogue, Renaissance theology involved investigations of doctrinal concordia (harmony), exploring and restoring divine truths contained in disparate religious and philosophical traditions. Giovanni Pico della Mirandola (1463–1494), who described himself as the 'Count of Concord', introduced themes of religious universalism in his Oration on the Dignity of Man , and his 900 conclusions contained a detailed exploration of different doctrines in search of concordia . Pico's claims even extended to a kind of divinisation of the human condition, enabled only by a proper understanding of universally concordant divine wisdom.

Pope Innocent VIII invoked canon law when he outlawed thirteen of Pico's claims as heretical, punishing him with excommunication. But this was overturned by Innocent's successor, Pope Alexander VI, who issued a papal brief in 1493 — a formal document with legal force — absolving Pico and nullifying his excommunication. This pendulum swing, expanding and contracting boundaries of Catholic orthodoxy, was a hallmark of Renaissance theological inquiry, reaching peak doctrinal flexibility around the time Michelangelo completed his Sistine ceiling commission. Many have proposed that Michelangelo's theological advisor on the program was Egidio da Viterbo, prior general of the Augustinian order at the time — a position that the new pope has likewise occupied.
Marsilio Ficino had an enduring interest in a universal ancient theology he called the prisca theologia , which consisted entirely of wisdom derived from pre-Christian philosophers and seers, including the sibyls that appear in Michelangelo's frescoes. Ficino viewed the metaphysics he found there as a form of natural theology — divine truth derived from reason — and he felt that both natural philosophy (science) and divine theology (religion) could be explained and contained by Platonic metaphysics.
Ficino wanted to inspire his generation to rekindle the combined practice of philosophy and theology:
Therefore, the prophets of the Hebrew and Essenes were inclined to wisdom and priesthood simultaneously. The philosophers among the Persians, because they were in charge of sacred rites, were called Magi [which is to say, priests]. The Indians consulted the Brahmins on both the nature of things and the purification of souls. Among the Egyptians, mathematicians and metaphysicians took up the priesthood and the kingship. Among the Ethiopians, the gymnosophists were at once teachers of philosophy and prelates of religion. The same tradition prevailed in Greece under Orpheus and Pythagoras.
Ficino sought to unite two groups of Renaissance thinkers who would often fail to engage with each other: 'I therefore exhort and implore all philosophers to reach out and embrace religion firmly, and all priests to devote themselves diligently to the study of legitimate wisdom.'
Under the belief that natural philosophers would be convinced by the arguments of Plato, he hoped to redirect them away from the shadows of things and toward the underlying divine truth of incorporeality. Meanwhile, he was encouraging the priesthood to embrace the legitimate wisdom of philosophy, thus dissolving the boundary between theology and philosophy.

Prominent depictions of pagan sibyls in communion with Hebrew prophets are unique to the Italian High Renaissance and reflect a chapter in the history of religion that is not well understood.
On the ceiling of the chapel where the cardinals elected Pope Leo XIV is Michelangelo's kaleidoscopic hieroglyphic, telling us about a time when Pope Francis's vision of the inclusive and synodal church would have seemed mainstream. A story about a time when universal concordia reigned supreme — a story told by a generation who believed in the arrival of a Golden Age, when the truth of unity would outlast the deceit of division.

Gas workers uncover 1,000-year-old mummy in Peru
A crew of workers accidentally discovered a mummy more than 1,000 years old while installing gas pipes in Peru's capital Lima, their employer and archaeologists said Thursday. The mummy was found last week in a tomb underneath a street north of Lima, said archaeologist Jesus Bahamonde. The mummy was covered in a shroud in a seated position, arms and legs bent. Pottery was also found in the tomb which was dated to the pre-Inca Chancay civilization that lived around the Lima region between the 11th and 15th centuries. It was believed to be part of a large, ancient cemetery. Lima, a city with over 10 million inhabitants, also houses more than 500 archaeological sites. Gas company Calidda has reported more than 2,200 chance archaeological discoveries since 2004.

Gen Z thinks you're ‘old' at this insultingly early age
A survey by US education firm Edubirdie — which polled 2000 Gen Z and young Millennials, defined as those born in the late '90s and early 2000s — dared to ask the younger generations the question, 'When does old age really start?' For 22 per cent of Gen Zers, they think that by the time you've reached 35, you're toast. An additional 26 per cent believe that 40 is the true marker of elderliness. Thus, almost half of Gen Z thinks that anything over the age of 40 is old. Meanwhile, only a quarter of people tend to go grey under 40. Admittedly, a sizeable 31 per cent portion of Gen Z respondents reportedly believe that oldness sets in at 60, making for a more conventional vision of senility. This disproportionately large percentage of Zoomers who believe old age begins at 35 is likely due to a generational fixation on youth, fast-paced trends and appearance, some say. 'I feel like Gen Zers tie a lot of their identity to their youth and look at millennials as the older wise men, and wise women. And, while I do appreciate that, I'm also just, like, we're only, like, five years from where you are,' Mike Mancusi, a 34-year-old comedian who created a recent viral TikTok on the Gen Z and Millennial divide, recently told Newsweek. 'I'm sure every single generation feels this way about the younger generation. I seriously doubt this is a unique generational relationship,' he said. In a Reddit thread on the subject, the generations battled it out to decide whether or not the 22 per cent of Gen Zers are simply living life day-by-day, with no consideration for their own — apparently impending ageing — or if there's a point to the polled pandemonium. 'Hey Gen Z. Millennial here with a friendly reminder that you'll be old before you even know it,' warned a decidedly bitter commenter. 'They say this now until it's time for them to be in their 30s, and the next generation calls them old at that age,' agreed another. While some Zoomer Redditors didn't mince their words, others offered respectful words to the wise about their elders. '30 is old. 30 is basically half your life,' reasoned one reply — although, logically speaking, that seems like it would make 30 middle-aged. While a significant portion of surveyed Gen Zers thought that people in their 30s were old, others curiously called out 27 as an 'old' age marker. 'I had a Zoomer intern last summer call a 27-year-old 'old'… Perspective is weird,' reflected an older Millennial. 'I'm 22, and I see anyone older than like 27 as old,' another commenter wrote. 'I think it's hard to argue that 35 is 'old' but by that age, you're certainly not young,' one thorough thinker explained. 'It's definitely a little stifling to be in a place with a younger crowd and see 35+ adults trying to party with all the people in their early 20s. Like I expect to be married with children by the time I'm 35, and even if I'm not, I understand that it's time for me to move on from the activities I did in my 20s.' As more and more Gen Zers enter the workforce and 'adult life,' some expect that they'll change their minds about the mid-30s cut-off for youth. After all, the infamously sober generation is consuming more alcohol than ever before, leaving behind their 'grandma core' ways, so perhaps anything could happen — there may be hope yet for all of the greying Millennials out there.
