Benedictine and Franciscan Monks: Forgotten Inventors

   Usually, when we think of religious orders, these things come to mind: a cloister, an abbey, a library, prayer in solitude, detachment from the world… All this in the cradle of a period defined as "dark" by historiography up to Romanticism: the Middle Ages . In this period the monks - especially the Benedictines of the various orders - were the custodians of Judeo-Christian but also classical culture, since thanks to their patient and meticulous transcriptions as scribes we have received almost all of the Greek and Latin works which we study today. Today we are grateful to them first of all for this.   However, many do not know that many products - material and immaterial - that we consume and use every day, come from monks who, using their ingenuity nourished by a profound spirituality, invented them due to practical necessities.    Personally, I find it amazing!    Let's begin…   The heavy plow   Plows were a primary agri...

Why Doesn't it Rain Inside the Pantheon Despite the Hole in the Dome?


The Pantheon, an architectural marvel of ancient Rome, stands as a testament to the ingenuity of its builders. One of the most intriguing aspects of the Pantheon is its oculus, a large circular opening in the center of the dome. Despite this hole, rain doesn't pour into the interior of the building. Let's delve into the fascinating engineering and design principles behind this phenomenon.

Ancient Engineering Mastery

Constructed between 118 and 128 AD during the reign of Emperor Hadrian, the Pantheon was originally built as a temple dedicated to all the gods of ancient Rome. Its dome, which spans an impressive 43 meters in diameter, was the largest of its kind until the 15th century. This architectural marvel was built primarily using concrete, a material that the Romans perfected, along with bricks and marble.

 The Oculus: Function and Symbolism

At the apex of the dome lies the oculus, a circular opening with a diameter of approximately 8.7 meters. Serving as the main source of light and ventilation for the interior, the oculus also holds symbolic significance, representing the connection between the temple and the heavens.


The Role of the Oculus in Rain Prevention

 Despite the presence of the oculus, rainwater rarely enters the Pantheon's interior. This phenomenon can be attributed to several architectural and environmental factors.

Dome's Sloped Design

 One crucial element of the Pantheon's design is the gentle slope of the dome. The dome is slightly convex, meaning it bulges outward at the top. This curvature, along with the oculus at the dome's apex, directs rainwater away from the center of the building, preventing it from entering the interior.   


Drainage System

 Another ingenious feature is the floor's sloping design, which directs any water that does enter the building towards strategically placed drains. These drains are located along the perimeter of the floor, ensuring efficient water removal and preventing puddles from forming inside the Pantheon.

 

Hydraulic Concrete

 The Romans used a special type of hydraulic concrete known as pozzolana to construct the Pantheon. This concrete, made from a mixture of volcanic ash, lime, and water, not only provided incredible strength and durability but also had hydraulic properties. This means that it could set and harden even when submerged in water, making it ideal for structures exposed to the elements.

Natural Ventilation

 The oculus serves another vital function beyond letting in light. It acts as a chimney, facilitating the circulation of air within the building. As warm air rises, it is drawn out through the oculus, creating a natural ventilation system that helps to keep the interior dry and comfortable. 

Historical Accounts and Modern Observations

Throughout history, visitors to the Pantheon have marveled at its ability to remain dry despite rain falling through the oculus. Modern studies and observations continue to confirm the effectiveness of the Pantheon's design in preventing water ingress.

Conclusion

The Pantheon's enduring ability to repel rainwater through its oculus is a testament to the advanced engineering and architectural prowess of ancient Rome. Through meticulous design, innovative materials, and a deep understanding of physics, the builders of the Pantheon created a structure that continues to inspire awe and admiration centuries after its construction. As visitors gaze up at the open sky through the oculus, they are reminded not only of the heavens above but also of the remarkable achievements of human ingenuity on Earth.

Aren’t We All Poor Things?

  "Poor Things!", released in Italian theatres on January 25 2024, is a film by director Yorgos Lanthimos that presents itself as a startling and thought-provoking work. Through grotesque atmospheres and surreal hues, the film revisits the myth of Frankenstein in a modern key, focusing on the female figure of Bella Baxter (Emma Stone). Bella, an emancipated woman with a sexuality that was free for her time, is brought back to life by the scientist God (Mark Ruffalo) after a suicide attempt. However, her brain is replaced with that of the foetus she was carrying, creating a hybrid and unique creature.   Like Frankenstein's monster, Bella finds herself catapulted into a world that does not understand or fear her. Her childlike innocence clashes with the cruelty and hypocrisy of Victorian society, leading her to have grotesque and tragicomic experiences. Lanthimos, through the figure of Bella, explores deep and universal themes: diversity, the search for a place in the world...

Los Campesinos! A Journey Through Their Music

  Los Campesinos! is an indie pop band from Wales formed in early 2006 at Cardiff University. History The only remaining original members are Gareth Paisey (vocals), Neil Turner (guitar) and Tom Bromley (guitar), followed by Rob Taylor (guitar), Kim Paisey (keyboards and vocals), Matt Fidler (bass guitar) and Jason Adelinia (drums), but as stage names, they all replace their surnames with "Campesinos!", that in Spanish translates to "peasant" or "country person". The band's earliest compositions were influenced by post-rock, though no recordings from this era are known to circulate publicly. The band performed their first gig on 8 May 2006 at a student union club night and an early demo was recorded featuring the songs "Death To Los Campesinos!", "It Started With A Mixx", "Sweet Dreams, Sweet Cheeks", and "You! Me! Dancing!". The songs were posted on the band's Myspace account, making their reputatio...
