The Last Judgement of the Baptistery
A masterpiece of salvation, damnation, and eternity in the heart of Florence.
In the western sections of the golden vault of the 13th-century mosaics in the Baptistery shines a gigantic depiction, both beautiful and terrifying: the Last Judgment! Christ returns at the end of time to judge the living and the dead. What a marvelous effect those thousands of tesserae, arranged in elaborate designs, must have created once when reflecting the light of the hundreds of candles burning inside the temple. No Florentine could be unaware of this representation, especially in the past, when anyone born in Florence was baptized beneath these mosaics. Dante Alighieri drew inspiration from them in composing the Divine Comedy, and Vincenzo Borghini when devising the iconographic program of the other great Florentine Last Judgment, painted by Vasari and Zuccari in the Cathedral Dome. Even Michelangelo, when frescoing his vision of the Last Judgment in the Sistine Chapel, though different, must have had this cycle in mind. The Last Judgment is the culmination and keystone of the Baptistery’s vast mosaic cycle: 1,200 square meters of colored and gilded glass tesserae, created by great artists to form a cosmic narrative that includes the angelic hierarchies and spans from the creation of the world and the first ancestors, through the stories of Genesis, the tales of the patriarch Joseph, then Christ and Mary, and finally John the Baptist.
Human history and all creation stand here before the eternal Judge. In the western section, an artist whom many scholars identify as Coppo di Marcovaldo placed the immense Christ of the parousia, or “second coming.” Togate like an emperor, with the stigmata in his hands and feet as a testament to his resurrection, he sits upon a throne in the sky, enclosed within a circle eight meters in diameter, symbolizing perfection and eternity. In the frame and halo, convex mirrors once amplified this epiphany. Below him, the dead emerge from stone tombs resembling those that, in the Middle Ages, were actually found near the Baptistery. To the observer’s left, angels with multicolored wings and regal tunics lift the lids of the sepulchers of the righteous, who awaken naked with gestures of friendship and joy; on the opposite side, the sarcophagi of the damned are uncovered, and they are dragged away, weeping, by monstrous blue, purple, and black devils, with bat or crow wings, horns, feral faces, and thick worms or serpents coiling around their bodies. Above them, Christ himself separates them: with his right hand he welcomes the righteous, and with the other he repels the wicked. This division is completed in the adjacent sections: to the southwest opens the vision of Paradise, while to the northwest lies the abyss of Hell.
A group of the saved—men and women—dressed in the garments of clergy, rulers, or commoners of various classes, is already absorbed in contemplation; behind them, children in luxurious clothes are accompanied by an angel holding an unfolded scroll, on which is written the phrase (in Latin) from the Gospel of Matthew (25:34), in which Jesus announces the fate of the righteous on the Day of Judgment: “Come, you who are blessed by my Father. Inherit the kingdom prepared for you from the foundation of the world.” Indeed, just beyond, a second angel opens a door inthe sky: it is the gate of Paradise! Beyond it stretches a garden with a flowering meadow and fantastical trees. Among them, on two thrones, sit three patriarchs—Abraham, Isaac, and Jacob—who welcome into their arms the souls of the righteous, depicted as children in white robes edged with gold. According to Christian tradition, the souls of the righteous, awaiting the coming of Christ and full beatitude, rested in the “Abraham's side”
On the opposite side lies Hell: a weeping and despairing mass of men and women, monks and kings, princes, peasants, and merchants, pushed into an abyss of chasms, darkness, and flames, populated by multicolored demons with human features mixed with animal parts of goats, oxen, worms, and serpents. Like ruthless executioners, they devour the damned, throw them into the flames, push them into the jaws of horrible toads and snakes, impale them on spits, and anoint them with boiling pitch. At the center, the king of that realm, Lucifer: a gigantic horned monster devouring souls with his multiple mouths, some in the form of serpents emerging from his buttocks and the sides of his head (Dante certainly remembered this when imagining the three-faced Lucifer of the Divine Comedy!). In one corner, Judas, identified by an inscription, eternally repeats his hanging.
But it does not end there, for the two otherworldly realms are surmounted by two additional registers. In the middle register, next to the Judge, sits an assembly of fourteen thrones, on which—flanked by pairs of angels—sit the Virgin Mary and John the Baptist, placed respectively to the right and left of Christ, followed by the Twelve Apostles. In the upper register, on either side of two angels ringing the Judgment bells, converge two solemn processions of angels in regal vestments, carrying the symbols and instruments of the Passion.
This iconographic system had a function beyond mere doctrinal education or moral admonition, being an integral part of the space and liturgical rites. The figure of Christ the Judge, positioned above the altar, allowed the faithful to associate him with the chalice and bread during Mass, emphasizing the real presence of the Risen One in these elements. Furthermore, the Last Judgment occupied a symbolically crucial position for the baptized: entering the baptismal font from the east and emerging toward the west, the individual completed a meaningful journey, symbolizing death in sin and resurrection in Christ, thus beginning the path of salvation depicted in the vault.
The very concept of baptism, associated with the hope of Resurrection, is the keystone of the entire temple. Situated in a cemetery area, the Baptistery alluded to this Christian hope, guaranteed to those who had received this Sacrament there. Its octagonal form evoked the christian symbolism of the number eight: the octava dies, the eighth day, following the seven of Creation, a sign of the eternity of the blessed. Ideally, the Judge Christ is placed on this eighth side of the vault, with the symbols of Resurrection above the risen and those emerging from the waters of baptism.
