The Gates of Paradise

The Florence Baptistery (Italian: Battistero di San Giovanni), also known as the Baptistery of Saint John, 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 in Spoleto, the Temple of Clitumnus, the church of Sant’Alessandro in Lucca.

The Baptistry 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. The east doors were dubbed by Michelangelo the Gates of Paradise.

The Italian poet Dante and many other notable Renaissance figures, including members of the Medici family, were baptized in this baptistry.

East doors, or Gates of Paradise, by 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 baptistry. (The original location for these doors was the east side of the baptistry, but the doors were moved to the north side of the baptistry 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. 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 baptistry, 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 (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”.
