The Battistero of San Giovanni
For the baptistery with the same name in Siena, see Battistero di San Giovanni (Siena)

The Florence Baptistery or Battistero di San Giovanni (Baptistery of St. John) is a religious building in Florence (Tuscany), Italy, which has the status of a minor basilica.

The octagonal Baptistery stands in both the Piazza del Duomo and the Piazza di San Giovanni, across from the Duomo cathedral and the Giotto bell tower (Campanile di Giotto). It is one of the oldest buildings in the city, built between 1059 and 1128. The architecture is in Florentine Romanesque style.

The Baptistery is renowned for its three sets of artistically important bronze doors with relief sculptures. The south doors were done by Andrea Pisano and the north and east doors by Lorenzo Ghiberti.[1] The east pair of doors was dubbed by Michelangelo "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.[2] In fact, until the end of the nineteenth century, all Catholic Florentines were baptized here.

For a long time, it was believed that the Baptistery was originally a Roman temple dedicated to Mars, the tutelary god of the old Florence.[3]

The founder of this legend was not Dante, as sometimes claimed, but Giovanni Villani 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 Theodelinda, queen of the Lombards (570-628) to seal the conversion of her husband, King Authari.


The octagon had been a common shape for baptisteries for many centuries since early Christian times. 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 (548).

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.[citation needed] The granite pilasters were probably taken from the Roman forum sited at the location of the present Piazza della Reppublica. 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 from about 1059

The present much larger 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 apse on the west side in 1202. 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 (see Loggia dei Lanzi).

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.


View from the outside with the Gates of Paradise

The Baptistery has eight equal sides with a rectangular addition on the west side.

The sides, originally 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 prototype, influencing many architects, such as Leone Battista Alberti, in their design of Romanesque 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 was it was made rectangular in 1202.

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'Avanzano, 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 (Wool Merchants' Guild) to design the baptistery north doors. The existing north doors had been a votive offering to spare Florence from a new scourge such as the Black Death in 1348. Seven sculptors competed, including Lorenzo Ghiberti, Filippo Brunelleschi, Donatello and Jacopo della Quercia [4], 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 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. Rustici may have been aided in his design by Leonardo da Vinci, who assisted him in the choice of his tools.

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.

Michelangelo referred to these doors as fit to be the "Gates of Paradise" (It. 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.[5] One of the few copies made in the 1940s is installed in Grace Cathedral, in San Francisco.

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 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.

Images of the doors


View towards the altar inside the Baptistery

The vast interior of the Baptistery recalls the interior of the Pantheon in Rome. The interior is rather dark, light entering through small windows in the ambulatory and through the lantern. The interior is divided in a lower part with columns and pilasters and an upper part with an ambulatory. The Florentines didn't spare any trouble or expense to decorate the baptistery. The interior walls are clad in dark green and white marble with inlaid geometrical patterns. The niches are separated by monolithic columns of Sardinian granite. The marble revetment of the interior was begun in the second half of the eleventh century.

The rectangular apse was faced with mosaics in 1225.

The building contains the monumental Tomb of Antipope John XXIII by Baldassare Coscia, designed by Donatello and his pupil Michelozzo Michelozzi. A gilt statue, with the face turned to the spectator, reposes on a deathbed, supported by two lions, under a canopy of gilt drapery. He had bequeathed several relics and his great wealth to this baptistery. Such a monument with a baldachin was a first in the Renaissance.

The mosaic marble pavement was begun in 1209. The geometric patterns in the floor are complex. Some show us oriental zodiac motifs, such as the slab of the astrologer Strozzo Strozzi. There was an octagonal font, its base still clearly visible in the middle of the floor. This font, which once stood in the church of Santa Reparata, was installed here in 1128. Dante is said to have broken one of the lower basins while rescuing a child from drowning. The font was removed in 1571 on orders from the grand duke Francesco I de' Medici. The present, and much smaller, octagonal font stands near the south entrance. It was installed in 1658 but is probably much older. The reliefs are attributed to Andrea Pisano or his school.

Mosaic ceiling

Mosaic ceiling

The Baptistery is crowned by a magnificent mosaic ceiling. The earliest mosaics, works of art of many unknown Venetian craftsmen (including probably Cimabue), date from 1225. The covering of the ceiling started under the direction of the Franciscan friar Jacopo da Torrita and was probably not completed until the fourteenth century.

This mosaic cycle depicts in the three sections above the high altar, the Last Judgment with a gigantic, majestic Christ and the Angels of Judgment at each side by Coppo di Marcovaldo, the rewards of the saved leaving their tomb in joy (at Christ's right hand), and the punishments of the damned (at Christ's left hand). This last part is particularly famous: evil doers are burnt by fire, roasted on spits, crushed with stones, bit by snakes, gnawed and chewed by hideous beasts. These scenes remind us of later works showing us in grisly detail the horrors of hell, such as The Last Judgment or the panel Hell (from the triptych The Garden of Earthly Delights), both by the Flemish painter Hieronymus Bosch.

Dante Alighieri grew up looking at these mosaics and these images of death and resurrection must have had a deep impact on him.

The other scenes on the ceiling depict different stories in horizontal tiers of mosaic : (starting at the top) Choirs of Angels, Thrones, Dominations, and Powers; stories from the Book of Genesis; stories of Joseph; stories of Mary and the Christ and finally in the lower tier : stories of Saint John the Baptist.

In the drum under the ceiling are many heads of prophets, attributed to Gaddo Gaddi, a friend of Cimabue.
