How long did brunelleschi work on the duomo

It used a special rope feet long and weighing over a thousand pounds—custom-made by shipwrights in Pisa—and featured a groundbreaking clutch system that could reverse direction without having to turn the oxen around. Having assembled the necessary tool kit, Brunelleschi turned his full attention to the dome itself, which he shaped with a series of stunning technical innovations. His double-shell design yielded a structure that was far lighter and loftier than a solid dome of such size would have been.

He wove regular courses of herringbone brickwork, little known before his time, into the texture of the cupola, giving the entire structure additional solidity. Throughout the years of construction Brunelleschi spent more and more time on the work site. He oversaw the production of bricks of various dimensions and attended to the supply of choice stone and marble from the quarries. He led an army of masons and stonecutters, carpenters, blacksmiths, lead beaters, barrelmakers, water carriers, and other craftsmen.

Brunelleschi took particular care of his workers, both for their safety and to ensure that the dome progressed as rapidly as possible.

He ordered that their wine be cut with water to keep them sharp on the heights this provision was revoked under pressure by dissatisfied workers and added parapets to the suspended platforms to prevent them from falling—or looking down from the dizzying height of the dome. According to popular legend, Brunelleschi could also be a hard taskmaster. When masons went on strike demanding better pay, we are told, he called in scabs from Lombardy, and relented only when the masons returned, hats in hand, and agreed to resume their jobs—at reduced wages.

He also had to contend with highly placed adversaries, led by the scheming Lorenzo Ghiberti. In the summer of , just before a wooden tension ring was to be laid around the dome, Brunelleschi suddenly took to his bed, complaining of severe pains in his side. When the baffled carpenters and masons asked how they were to position the enormous chestnut beams that made up the ring, he essentially delegated the task to his rival. Giovanni also composed a violent personal attack on Brunelleschi in sonnet form.

If they ever succeeded, Giovanni rather rashly promised, he would kill himself. Brunelleschi and his workmen eventually did their victory dance, though only after several more years of doubt and struggle. In cracks appeared in the east end of the cathedral nave beside the dome, forcing Brunelleschi to shore up the walls with iron tie bars. But soon after, he was released, and the cupola continued skyward at the average rate of about one foot per month.

On March 25, , the Feast of the Annunciation, Pope Eugenius IV and an assembly of cardinals and bishops consecrated the finished cathedral, to the tolling of bells and cheering of proud Florentines. A decade later another illustrious group laid the cornerstone of the lantern, the decorative marble structure that Brunelleschi designed to crown his masterpiece.

Soon after, on April 15, , Brunelleschi died, apparently from a sudden illness. The platforms for the workers were cantilevered from the walls of the dome and pockets were built in the walls to support these platforms. The accuracy of these pockets is remarkable, and it is believed that the platforms needed to be accurate and level so that the geometry of the dome could be ascertained by chains and string lines that were used to guide the masons in laying brick.

The unprecedented building strategies didn't stop there. All in all, the construction of Brunelleschi's brainchild took 16 years to complete although it took another decade for a lantern to be added on.

The construction of the Dome of Santa Maria del Fiore kicked off in and was completed in , and the end result was mind blowing to say the least. Brunelleschi died ten years after the completion of the dome, and he was buried in the crypt of the cathedral. The nearby plaque commemorating his legacy celebrates his "divine intellect" and to this day, the unlikely visionary remains an architectural icon not just in Italy, but throughout the world.

No one had any idea how it would or could be done, including the artists who conceptualised it, but Florentines were determined to outdo the other cities in Tuscany, no matter how long it took.

They did not like the Gothic style of all the major monuments around Europe at the time with the distraction of the flying buttresses surrounding them, and the similar look they all had, so they looked to the ancient Romans for inspiration. They idolised their innovative building and technology and wanted to be held in the same esteem by their competing surrounding cities in Tuscany who were also erecting grand monuments for prestige. Ironically, after losing the baptistery door competition, Brunelleschi went to study ancient Roman structures, not to be heard of in history again before returning to Florence years later.

After being under construction for over years, the city of Florence was risking looking like fools to their competitors in surrounding areas with an unfinished cathedral and a seemingly insane and impossible task of building the largest dome structure Europe had ever seen.

They finally offered the challenge to the public seeking someone to find a solution that would be cost effective and possible. Of course, there was the possibility of building the dome with a wooden structure to support it, but that would end up being costly requiring over 4oo trees, lots of manpower and time.

When Brunelleschi entered the competition, he was the only one with an idea that did not involve wood, which caught the attention of the judges. Florence was so desperate for a solution, Brunelleschi won the competition without ever showing his plans. Although his forward thinking lost him the competition years before with the baptistery doors, it was exactly what Florence needed in this time of panic.

He had to persuade the judges, of course, and did so after concealing his plans for so long, that a simple egg was what finally convinced the judges. He told them that he would reveal his plans if any one of them could make the egg stand upright on the table. Although the judges protested that they themselves could have done the same, he slyly responded saying that if they knew what he knew, they could also build the dome. Essentially, they hired the guy with a secret plan and no experience.

Using his wit and secret design of the dome, which he himself was unsure of since he would need to build it to be certain that a few potential flaws could work, he won the competition and was allowed to move forward, being appointed two other designers, including his past rival, Ghiberti.

They started April The larger ones being St. In the 15th century, when it was completed, it was the largest cathedral in Europe. It is metres ft long, 90 metres ft wide at the crossing, and 90 metres high from the floor to the bottom of the dome.

Not only did he come up with an ingenious masonry idea for how to build a freestanding brick structure with curved walls without the use of a wooden frame, he also invented the tools he needed to do so. The technology at the time for lifting heavy objects was similar to a wooden gerbil exercise wheel, powered by a human, but only reached a limited height. Brunelleschi used oxen walking in a circle for the first time and created a type of mechanism that precedented anything they had seen at the time using a three cogged wheel system to control the lifting or lowering of heavy objects without moving the walking direction of the oxen, now known as the Reverse Gear.

For years, the structure was a huge mystery to scholars who needed to find the missing pieces to their theories on how the dome was built. It was something never tried before. Brunelleschi had nothing but critics and had to convince even his building team to trust him, who were putting their lives in his hands working at 51 meters feet in the air on a structure seemingly doomed to cave in. After visiting the Duomo Florence Italy from all sides, the final thing to do to complete the experience is to climb up to the top!

The stairs were originally built to help the workers during the construction and for maintenance, not for the general public. They are small and narrow but offer a closer look to the architectural magnificence and frescoes that line the inside of the cupola.

By looking up the left facade of the Cathedral, you may notice a large ox-head with horns. Legend says that one of the workers had an affair with the wife of a tailor who lived in a house in Via Ricasoli. When the adultery was discovered, the tailor denounced both his wife and the lover to the ecclesiastical court.

The worker decided to place the head of the cow facing the windows of the jealous tailor to remind him every day his condition of betrayed husband. Although another possibility is that the builders were simply paying homage to the animals that transported heavy materials during construction.
