Brunelleschi was a goldsmith in a Florentine workshop and was a member of the goldsmiths' guild, although his interest in
mathematics led him to architecture. In 1401 Brunelleschi made himself known by winning the competition for the second door of Baptistery "ex aequo" with Lorenzo Ghiberti. Brunelleschi was not happy with the decision and allowed Ghiberti to have the
commission. Ghiberti finished those doors and many years later won the commission to build another set of doors for the
bapistery which came to be know as the famous "Gates of Paradise."
A rivalry between the two began that would last for the
rest of their lives.One incident between the two men occurred when both served on the council overseeing the construction of Santa Maria del
Fiore.Brunelleschi worked and studied in Rome with his friend Donatello, where he learned about Classical architecture. It is also
rumored that he travelled to Constantinople before its fall to the Ottoman Turks to study the structure of the Hagia Sophia.
His interests extended to mathematics and engineering and the study of ancient invented hydraulic machinery and elaborate
clockwork, none of which survive. He also had a brief and disastrous cameo in the world of shipmaking, when he built a
monstrous ship called Il Badalone to transport marble to Florence from Pisa up the Arno River.
The ship sank on its first
voyage, along with a sizable chunk of Brunelleschi's personal fortune.Brunelleschi is remembered as an architect who established new classic canons of serene rhythms, clear geometry, and
symmetry, often using simple materials: gray pietra serena and whitewashed plaster. When he first entered his architecture
field, he was frequently thrown out of meetings due to his temper. He was rescued from bankruptcy by the Medici family, who
were impressed by his designs and contracted him to design and build projects for them.
Besides accomplishments in architecture, Brunelleschi is also credited with inventing one-point linear perspective, which
revolutionized painting and allowed for naturalistic styles to develop as the Renaissance digressed from the stylized figures
of medieval art.
Brunelleschi's dome of Santa Maria del Fiore.In 1418, a competition was announced for proposals on how to bridge the central crossing of the cathedral in Florence (Santa
Maria del Fiore). Brunelleschi's bid was backed by the then less important family, the Medici, who stood to benefit hugely
from the completion of the dome. His design, which offered to build the cupola in circular cone-shaped courses of brickwork
forming two shells - one light outer shell - and the main shell (the scaffold) so thick that it contains a closed circle
without a framework of scaffolding, won the competition, and in 1423 he was put in complete charge of the Duomo's building
The internal dome is made with 16 ribs to take the pressure off the dome. As well, the dome is made of brick with the
herring bone style to take additional stress off the dome. Its completion took most of his life. The main structure was
finished by 1434. The four tribunes in the apse were completed in 1438. The dome was only completed with a lantern in 1461 by
Michelozzo. Andrea del Verrocchio added the gilt copper ball in 1496. The church's dedication took place on 25 March 1436,
accompanied by a grand ceremony; music for the occasion, the motet Nuper rosarum flores, was written by Guillaume Dufay.
While construction was proceeding, Brunelleschi designed and built the Pazzi Chapel in the cloister of the church of Santa
Croce, which was actually begun in 1442 after long negotiations. The chapel, where members of the Pazzi family were to be
entombed, was meant to function as a chapter house for the Franciscans of Santa Croce. Brunelleschi's ribbed hemispherical
dome is expressed on the exterior as a low tiled flattened conical roof on a low plain drum with small oculus windows.
Inside, under the dome, the chapel is almost a cube, extended by barrel-vaulted bays on two sides. Pilasters and hemicyclic
arches articulate the walls. The sedate materials are white stucco and the gray stone Florentines call pietra serena.
Ospedale degli Innocenti, FlorenceThe Duomo was not Brunelleschi's sole achievement in architecure; he also designed other
famous buildings. The Ospedale degli Innocenti (The foundling children's hospital or orphanage) started 1419 is considered as
the first real renaissance building. The hospital, which features a loggia that people could take refuge from the weather
under, was built and managed by the silk guild of Florence. Brunelleschi's design, which was based on Classical styles with
simple rhythm, held simple ratios in the columns and Roman arches. If a horizontal line is drawn from the top of each column,
a square is created out of the height and width of the column and the distance from one column to the next. The diameter of
each arch is also the same distance as the height of each square. Above each column is a tondo style, terra cotta sculpture,
which were added after Brunelleschi's initial design.
