Wow! This story is so amazing. He must have had a gift from above to create such a magnificent structure with no known architecture training, even with the limit understanding of physics and mechanics at the time. Even some of the heavily life equipment used in the construction and building of the dome - have to be create from imagination to reality with no formal history of success or failures. What marvel and person he was. He had to be stubborn and strict (and very difficult to work with) - Strictly task oriented person. But, look what he left for the world to see and admire for generations to come? Faith or religion may have played some part of his driven passion - But, the desire to achieve something when all expect you to fail - must have been his passion and his faith. He left no records, no documents, and no traces of his created plans in the planning and creation of this. Even modern experts of today - are still guessing with all the advancements and technology man/woman have created. Sometimes we do not know if the Man upstairs is talking to us (and he does not pick or chose who he gives a gift of his power to - because I do not think he looks for perfection). He looks for those who never give up or give in and want to leave a mark of goodness on the world to marvel Gods' power and gift - I believe than Man upstairs is saying - I AM IN CHARGE and DON’T FORGET. What a beautiful story and legacy for all man and woman kind and of all faith to admire.

Nearly six centuries after it was completed, the dome of Santa Maria del Fiore cathedral in Florence—a cathedral known around the world simply as il Duomo—remains that city's icon and greatest pride. Built without flying buttresses or freestanding scaffolding, using experimental methods that many contemporaries believed would surely fail, the 150-foot-wide (46-meter-wide) dome effectively ignited the creative explosion known as the Renaissance.
Its creator, Filippo Brunelleschi, a homely, hot-tempered goldsmith with no serious architectural training, is a hero to his fellow Florentines—and to one modern architect in particular. (Read more about il Duomo in the February 2014 issue of National Geographic magazine.)
Last April 15, on the 567th anniversary of Brunelleschi's death, I stood in the portal of the Florence cathedral, a few feet from his grave, as a procession in Renaissance dress entered the basilica—double ranks of halberdiers with gleaming weapons and breastplates, maidens in sweeping brocade gowns carrying wreaths of laurel and myrtle, drummers and trumpeters whose music filled the church and echoed in Brunelleschi's dome as on the day he was buried.
The procession descended into the crypt to lay the wreaths on Brunelleschi's slab. A portly gentleman in his early 70s bent down and laid his hand on the marble, his head bowed reverently, his breathing audible. No one in history has devoted himself more wholeheartedly to Brunelleschi and his memory than this man, Massimo Ricci, an architect from an ancient Florentine family who walks at the head of this memorial procession each year.
Ricci has spent much of his life trying to work out the construction techniques that Brunelleschi used to build the dome—still the largest masonry dome on Earth.
Ricci's identification with Brunelleschi has been so intense that at times he says he almost feels the great architect standing, silent and invisible, beside him.
"We've developed a special, almost spiritual relationship," Ricci says in his throaty growl. "Sometimes I'm filled with gratitude for what he accomplished, what he left us. Other times he frustrates me so much, I tell him to go to hell."
Having Brunelleschi's spirit whisper in your ear may be about the only way to know for sure how he worked. Secretive to the end, he carried many mysteries of his dome to the grave.
To this day, we don't know where he got the inspiration for the double-shell dome, the herringbone brickwork, and the other features that architects through ensuing centuries could only marvel at. (Explore the hidden details of Brunelleschi's daring design.)
Perhaps the most haunting mystery is the simplest of all: How did Brunelleschi and his masons position each brick, stone beam, and other structural element with such precision inside the vastly complex cathedral—a task that modern architects with their laser levels, GPS positioning devices, and CAD software would still find challenging today?
For 40 years, Ricci has tried to answer these questions in the same way that Brunelleschi did: by trial and error. He has built scale models of Brunelleschi's innovative cranes, hoists, and transport ships. He has scoured the interior and exterior of the dome for clues, mapping each iron fitting and unexplained stub of masonry and cross-referencing them against the archival documents concerning the dome's construction.
And since 1989, in a park on the south bank of the Arno River half a mile downstream from Santa Maria del Fiore, he has been building a scale model of the dome that's 33 feet (10 meters) across at its base and consists of about 500,000 bricks.
"Theoretical models are fine for grasping the dome's geometry," Ricci says, "but of limited use in understanding the problems Brunelleschi dealt with while building the dome. And that's what really matters to me: how Brunelleschi put bricks together."
In the process of putting together half a million bricks, Ricci may have solved one of Brunelleschi's biggest secrets: how a web of fixed and mobile chains was used to position each brick, beam, and block so that the eight sides of the dome would arc toward the center at the same angle.
Inspired by documentary references to "the star of the cupola," Ricci started by suspending a star-shaped hub in the center of his model dome. From the eight points of this star he stretched eight chains radiating outwards and downwards to the walls of his model, attached to hooks in the walls, in the corners of the octagonal plan (similar hooks are present in the dome itself).
Next he linked these eight chains with horizontal ropes, which traced arcs along the eight sides of the octagon where the walls were rising. Seen from above, these ropes resemble the petals of a flower.
After last year's memorial procession ended, Ricci laid out for me some of the evidence for his theory of the dome's flower, which he considers to be the breakthrough in his conception of Brunelleschi's method. "In fact, Santa Maria del Fiore means Saint Mary of the Flower," Ricci notes. "And the symbol of Florence is a flower, the lily."
He smiles with evident satisfaction. "You see? The pieces of my theory fit together, as solidly as the duomo itself."

I'm Italian and I studied architecture, and one of the most fascinating work was Brunelleschi Dome, no doubts. The best place to admire it, is from "Piazzale Michelangelo". Here an example of what you can see at night, the dome and Florence Cathedral.
Great article and video. Very informative. I was in Florence back in November '13 and stood in awe of this beautiful cathedral and it's dome. I've seen a lot of cathedrals but this is my favorite. I even took a flight with my quadcopter and GoPro and got a video of it.
Florence is magical and beautiful :) Duomo is the highlight of the city esp from Piazzelle Michaelangelo. Check my blog for more details :) http://ishitasood.blogspot.in/2014/01/firenze-little-renaissance-town-so-you.html
@Davide Vadalà Your very lucky for studying architecture and what's more for admiring the Dome but above all simply for being Italian.
Best of luck and ciao
