The Florence Baptistery, also known as the Baptistery of Saint John (Italian: Battistero di San Giovanni), is a religious building in Florence, Italy, and has the status of a minor basilica. The octagonal baptistery stands in both the Piazza del Duomo and the Piazza San Giovanni, across from Florence Cathedral and the Campanile di Giotto.
The Baptistery is one of the oldest buildings in the city, constructed between 1059 and 1128 in the Florentine Romanesque style. Although the Florentine style did not spread across Italy as widely as the Pisan Romanesque or Lombard styles, its influence was decisive for the subsequent development of architecture, as it formed the basis from which Francesco Talenti, Leon Battista Alberti, Filippo Brunelleschi, and other master architects of their time created Renaissance architecture. In the case of the Florentine Romanesque, one can speak of "proto-renaissance", but at the same time an extreme survival of the late antique architectural tradition in Italy, as in the cases of the Basilica of San Salvatore, Spoleto, the Temple of Clitumnus, and the church of Sant'Alessandro in Lucca.
The Baptistery is renowned for its three sets of artistically important bronze doors with relief sculptures. The south doors were created by Andrea Pisano and the north and east doors by Lorenzo Ghiberti. Michelangelo dubbed the east doors the Gates of Paradise.
The Italian poet Dante Alighieri and many other notable Renaissance figures, including members of the Medici family, were baptized in this baptistery.
It was long believed that the Baptistery was originally a Roman temple dedicated to Mars, the tutelary god of the old Florence. The chronicler Giovanni Villani reported this medieval Florentine legend in his fourteenth-century Nuova Cronica on the history of Florence. However, twentieth-century excavations have shown that there was a first-century Roman wall running through the piazza with the Baptistery, which may have been built on the remains of a Roman guard tower on the corner of this wall, or possibly another Roman building. It is, however, certain that a first octagonal baptistery was erected here in the late fourth or early fifth century. It was replaced or altered by another early Christian baptistery in the sixth century. Its construction is attributed to Theodolinda, queen of the Lombards (570-628) to seal the conversion of her husband, King Authari.
Octagonal design
The octagon had been a common shape for baptisteries for many centuries since early Christian times. The number eight is a symbol of regeneration in Christianity, signifying the six days of creation, the Day of Rest, and a day of re-creation through the Sacrament of Baptism. Other early examples are the Lateran Baptistery (440) that provided a model for others throughout Italy, the Church of the Saints Sergius and Bacchus (527-536) in Constantinople and the Basilica of San Vitale in Ravenna.
The earlier baptistery was the city's second basilica after San Lorenzo, outside the northern city wall, and predates the church Santa Reparata. It was first recorded as such on 4 March 897, when the Count Palatine and envoy of the Holy Roman Emperor sat there to administer justice. The granite pilasters were probably taken from the Roman forum sited at the location of the present Piazza della Repubblica. At that time, the baptistery was surrounded by a cemetery with Roman sarcophagi, used by important Florentine families as tombs (now in the Museo dell'Opera del Duomo).
Construction
The present much bigger Baptistery was built in Romanesque style around 1059, evidence of the growing economic and political importance of Florence. It was reconsecrated on 6 November 1059 by Pope Nicholas II, a Florentine. According to legend, the marbles were brought from Fiesole, conquered by Florence in 1078. Other marble came from ancient structures. The construction was finished in 1128.
An octagonal lantern was added to the pavilion roof around 1150. It was enlarged with a rectangular entrance porch in 1202, leading into the original western entrance of the building, that became an apse, after the opening of the eastern door, facing the western door by Lorenzo Ghiberti of the cathedral in the 15th century. On the corners, under the roof, are monstrous lion heads with a human head under their claws. They are early representations of Marzocco, the heraldic Florentine lion (the symbol of Mars, the god of war, the original male protector of Florentia, protecting a lily or iris, the symbol of the original female patron of the town (Flora, the fertile agricultural earth goddess).
Between the fourteenth and sixteenth centuries, three bronze double doors were added, with bronze and marble statues above them. This gives an indication that the Baptistery, at that time, was at least equal to the neighbouring cathedral in importance.
The Baptistery has eight equal sides with a rectangular addition on the west side. The sides, originally constructed in sandstone, are clad in geometrically patterned colored marble, white Carrara marble with green Prato marble inlay, reworked in Romanesque style between 1059 and 1128. The pilasters on each corner, originally in grey stone, were decorated with white and dark green marble in a zebra-like pattern by Arnolfo di Cambio in 1293. The style of this church would serve as a prototype, influencing many architects, such as Leone Battista Alberti, in their design of Renaissance churches in Tuscany.
The exterior is also ornamented with a number of artistically significant statues by Andrea Sansovino (above the Gates of Paradise), Giovan Francesco Rustici, Vincenzo Danti (above the south doors) and others.
The design work on the sides is arranged in groupings of three, starting with three distinct horizontal sections. The middle section features three blind arches on each side, each arch containing a window. These have alternate pointed and semicircular tympani. Below each window is a stylized arch design. In the upper fascia, there are also three small windows, each one in the center block of a three-panel design.
The apse was originally semicircular, but it was made rectangular in 1202.
Baptistery doors
Andrea Pisano
As recommended by Giotto, Andrea Pisano was awarded the commission to design the first set of doors in 1329. The south doors were originally installed on the east side, facing the Duomo, and were transferred to their present location in 1452. The bronze-casting and gilding was done by the Venetian Leonardo d'Avanzo, widely recognized as one of the best bronze smiths in Europe. This took six years, the doors being completed in 1336. These proto-Renaissance doors consist of 28 quatrefoil panels, with the twenty top panels depicting scenes from the life of St. John the Baptist. The eight lower panels depict the eight virtues of hope, faith, charity, humility, fortitude, temperance, justice and prudence. The moulded reliefs in the doorcase were added by Lorenzo Ghiberti in 1452. There is a Latin inscription on top of the door: "Andreas Ugolini Nini de Pisis me fecit A.D. MCCCXXX" (Andrea Pisano made me in 1330).
The group of bronze statues above the gate depict The Beheading of St John the Baptist. It is the masterwork of Vincenzo Danti from 1571.
Lorenzo Ghiberti
In 1401, a competition was announced by the Arte di Calimala (Cloth Importers Guild) to design doors which would eventually be placed on the north side of the baptistery. (The original location for these doors was the east side of the baptistery, but the doors were moved to the north side of the baptistery after Ghiberti completed his second commission, known as the Gates of Paradise.)
These north doors would serve as a votive offering to celebrate the sparing of Florence from relatively recent scourges such as the Black Death in 1348. Many artists competed for this commission and a jury selected seven semi-finalists. These finalists include Lorenzo Ghiberti, Filippo Brunelleschi, Donatello and Jacopo della Quercia, with 21-year-old Ghiberti winning the commission. At the time of judging, only Ghiberti and Brunelleschi were finalists, and when the judges could not decide, they were assigned to work together on them. Brunelleschi's pride got in the way, and he went to Rome to study architecture leaving Ghiberti to work on the doors himself. Ghiberti's autobiography, however, claimed that he had won, "without a single dissenting voice." The original designs of The Sacrifice of Isaac by Ghiberti and Brunelleschi are on display in the museum of the Bargello.
It took Ghiberti 21 years to complete these doors. These gilded bronze doors consist of twenty-eight panels, with twenty panels depicting the life of Christ from the New Testament. The eight lower panels show the four evangelists and the Church Fathers Saint Ambrose, Saint Jerome, Saint Gregory and Saint Augustine. The panels are surrounded by a framework of foliage in the door case and gilded busts of prophets and sibyls at the intersections of the panels. Originally installed on the east side, in place of Pisano's doors, they were later moved to the north side. They are described by the art historian Antonio Paolucci as "the most important event in the history of Florentine art in the first quarter of the 15th century".
The bronze statues over the northern gate depict John the Baptist preaching to a Pharisee and Sadducee. They were sculpted by Francesco Rustici and are superior to any sculpture he did before. Leonardo da Vinci is said to have given him technical advice; the pose of John the Baptist resembles that of Leonardo's depiction of the prophet.
Ghiberti was now widely recognized as a celebrity and the top artist in this field. He was showered with commissions, even from the pope. In 1425 he got a second commission, this time for the east doors of the baptistery, on which he and his workshop (including Michelozzo and Benozzo Gozzoli) toiled for 27 years, excelling themselves. These had ten panels depicting scenes from the Old Testament, and were in turn installed on the east side. The panels are large rectangles and are no longer embedded in the traditional Gothic quatrefoil, as in the previous doors. Ghiberti employed the recently discovered principles of perspective to give depth to his compositions. Each panel depicts more than one episode. In "The Story of Joseph" is portrayed the narrative scheme of Joseph Cast by His Brethren into the Well, Joseph Sold to the Merchants, The merchants delivering Joseph to the pharaoh, Joseph Interpreting the Pharaoh's dream, The Pharaoh Paying him Honour, Jacob Sends His Sons to Egypt and Joseph Recognizes His Brothers and Returns Home. According to Vasari's Lives, this panel was the most difficult and also the most beautiful. The figures are distributed in very low relief in a perspective space (a technique invented by Donatello and called rilievo schiacciato, which literally means "flattened relief".) Ghiberti uses different sculptural techniques, from incised lines to almost free-standing figure sculpture, within the panels, further accentuating the sense of space.
The panels are included in a richly decorated gilt framework of foliage and fruit, many statuettes of prophets and 24 busts. The two central busts are portraits of the artist and of his father, Bartolomeo Ghiberti.
Although the overall quality of the casting is exquisite, some mistakes have been made. For example, in panel 15 of the north doors (Flagellation) the casting of the second column in the front row has been mistakenly overlaid over an arm, so that one of the flagellators looks trapped in stone, with his hand sticking out of it.
Michelangelo referred to these doors as fit to be the Gates of Paradise (Porte del Paradiso), and they are still invariably referred to by this name. Giorgio Vasari described them a century later as "undeniably perfect in every way and must rank as the finest masterpiece ever created". Ghiberti himself said they were "the most singular work that I have ever made".
Preservation of original art
The Gates of Paradise situated in the Baptistery are a copy of the originals, substituted in 1990 to preserve the panels after over five hundred years of exposure and damage. To protect the original panels for the future, the panels are being restored and kept in a dry environment in the Museo dell'Opera del Duomo, the museum of the Duomo's art and sculpture. Some of the original panels are on view in the museum; the remaining original panels are being restored and cleaned using lasers in lieu of potentially damaging chemical baths. Three original panels made a US tour in 2007-2008, and then were reunited in a frame and hermetically sealed with the intention of making the panels appear in the context of the doors for public viewing. One of the few copies made in the 1940s is installed in Grace Cathedral, in San Francisco; copies of the doors are also crafted for the Kazan Cathedral in Saint Petersburg, Russia and in 2017 for the Nelson-Atkins Museum of Art in Kansas City, Missouri.

The two porphyry columns on each side of the Gates of Paradise were plundered by the Pisans in Majorca and given in gratitude to the Florentines in 1114 for protecting their city against Lucca while the Pisan fleet was conquering the island.
The Gates of Paradise are surmounted by a (copy of a) group of statues portraying the Baptism of Christ by Andrea Sansovino. The originals are in the Museo dell'Opera del Duomo. He then left to Rome to work on a new commission, leaving these statues unfinished. Work on these statues was continued much later in 1569 by Vincenzo Danti, a sculptor from the school of Michelangelo. At his death in 1576 the group was almost finished. The group was finally completed with the addition of an angel by Innocenzo Spinazzi in 1792.
