In 1418, Filippo Brunelleschi was tasked with building the largest dome ever seen at the time. He had no formal architecture training. Yet experts still don't fully understand the brilliant methods he used in contructing the dome, which tops the Santa Maria del Fiore cathedral in Florence, Italy.

He wasn't an amateur at all. He was indeed a mathematician and geometrician, he invented one point perspective (still fundamental today) and the planning of the dome took him several years. Good animation in the video but false informations, he worked really hard and was very well known as an architect at the time they gave him this project. It's not that he woke up and build the dome.

This video is very very nice but... Brunelleschi amateur?!? Let's be serious! I am an art historian and I can say undoubtedly Brunelleschi was not an amateur but an architect (and not only), one of the greatest and talented architect in history.

@stefanehrhardt2398 7 лет назад

The term amateur describes a person who had no formal training in a subject. And Brunelleschi had none. Due to little biographical information about his life it is not even clear how he transitioned from his actual profession as a goldsmith to architecture.

@stefanehrhardt2398 7 лет назад

I also know of the smaller dome. And this explains why they trusted him with this project even though he had no working samples speaking for his expertise by that time. This and the fact that he was the only applicant. ^^ Of course he studied architecture in Rome. He most likely worked as a goldsmith there too to make a living while spending his free time studying. But he did it completely on his own. Meaning there has been no professional training involved. He was a self taught architect - an amateur.

@islamsaid5082 7 лет назад

Yea it's weird to call Brunelleschi Amateur

@adolfothemidget 7 лет назад

Don't forget that in Italy during this era, most artisans and craftsmen began their careers as apprentices to Masters, and only upon several years of training and completion of a "master piece" were they elevated. Plus you had strong guilds (cf. unions) with their sets of rules.

7 years later. I mean, Brunelleschi clearly didn’t have any experiences. But he studied, his whole life, many architectural books and was also a great mathematician. He was a genius, a prospective master, and you can comprehend this by seeing his magnificent tile showing the Sacrifice of Isaac. Certainly, many aspects of his biography are uncertain and still a mystery. But one thing is sure: he wasn’t just a mere amateur.

@bodawei425 Год назад

The 'secret' is not one anymore. He interlocked the bricks in a 'fishbone' pattern that avoided the bricks to fall down under their own weight before the dome was completed. A genius design indeed. I am amazed that the dome is still standing today. Surely the most beautiful basilica in the world.

@r.michaelherberger9677 3 года назад

I remember being taught there was an iron chain at the base of the dome. The integration of metal and masonry was the innovation behind the dome. The problem is not the dome itself but the outward forces at its base. There would be a tremendous force from the weight from the beginning of construction and the horizontal element of that weight would push out the walls supporting the dome. Not to take away from the dome's actual construction but the use of the metal with the higher tensile strength would be a precursor for modern architecture and larger domes.

He adopted a brick laying technique used by the Persians and imported in Venice.

His knowledge as a clock maker allowed him to comprehend and apply the complex method that was otherwise unknown in Europe at the time.

@garywheeler7039 5 лет назад

There is more than one architect in that time that were goldsmiths. Perhaps goldsmiths could be trusted because they worked with gold and there were ways to make sure they weren't stealing even if it was tempting. It was a technical and artistic field that required thought and planning and the trust of wealthy people. One had to be a nerd that could be trusted, knew their stuff. and knew when they were getting over their head, and didn't exceed their depth. This kept out charlatans, fools, sociopaths, liars, thieves from the profession. It kept out Trumps.

Yup, sure looks like an "amateur". It was the 15th century, by modern standards no one back then had "formal architecture training", engineering was taught by experience. There weren't even modern universities at that point, all they could study was the highly advanced Arabic architecture or reverse-engineering Roman buildings with 1500 years. In no way was he an amateur, the dude spent all his life studying mathematics and engineering. Plus he had already been the lead architect of an earlier building. We might argue he had no pre-defined idea how to build a dome of these dimensions, but that's because no one in Europe else had either.

That is called a catenary. Well understood for a long time.

"No formal architecture training" ... mmmm this was the Renaissance. There were no specialized 'architects' unlike we do now, but at that time you studied mathematics, art, architecture etc in one... Calling Brunelleschi, the genius mathematician/engineer of the Renaissance, an 'amateur' is too much of a stretch

@@ZantidesYea, But Brunelleschi had studied architecture and by the time he won the competition for the design of the dome had already worked on three major buildings in Florence. He wasn't an amateur by any definition.
