The Basilica of San Vitale is one of the most important surviving examples of early Christian Byzantine art and architecture in Europe. The Roman Catholic Church has designated the building a "basilica", the honorific title bestowed on church buildings of exceptional historic and ecclesial importance, although it is not of architectural basilica form. It is one of eight Ravenna structures inscribed on the UNESCO World Heritage List.

The interior of the dome, with Baroque frescoes from the late 18th century.

The church was begun by Bishop Ecclesius in 526, when Ravenna was under the rule of the Ostrogoths and completed by the 27th Bishop of Ravenna, Maximian, in 547 preceding the Byzantine Exarchate of Ravenna.

The construction of the church was sponsored by Julius Argentarius, a banker and architect, of whom very little is known, except that he also sponsored the construction of the Basilica of Sant'Apollinare in Classe at around the same time. (A donor portrait of Julius Argentarius may appear among the courtiers on the Justinian mosaic.) The final cost amounted to 26,000 solidi (gold pieces), equal to 36.11 pounds. of gold. It has been suggested that Julian originated in the eastern part of the Byzantine Empire, where there was a long-standing tradition of public benefactions.

The central vault used a western technique of hollow tubes inserted into each other, rather than bricks. This method was the first recorded structural use of terra-cotta forms, which later evolved into modern structural clay tile. The ambulatory and gallery were vaulted only later in the Middle Ages.

The Baroque frescoes on the dome were made between 1778 and 1782 by S. Barozzi, U. Gandolfi and E. Guarana.

Architecture:

The church has an octagonal plan. The building combines Roman elements: the dome, shape of doorways, and stepped towers; with Byzantine elements: polygonal apse, capitals, narrow bricks, and an early example of flying buttresses. The church is most famous for its wealth of Byzantine mosaics, the largest and best preserved outside of Constantinople. The church is of extreme importance in Byzantine art, as it is the only major church from the period of the Emperor Justinian I to survive virtually intact to the present day. Furthermore, it is thought to reflect the design of the Byzantine Imperial Palace Audience Chamber, of which nothing at all survives. The belltower has four bells, the tenor one dating from the 16th century. According to legends, the church was erected on the site of the martyrdom of Saint Vitalis.  However, there is some confusion as to whether this is the Saint Vitalis of Milan, or the Saint Vitale whose body was discovered together with that of Saint Agricola, by Saint Ambrose in Bologna in 393.

Mosaic art:

The central section is surrounded by two superposed ambulatories. The upper one, the matrimoneum, was possibly reserved for married women. A series of mosaics in the lunettes above the triforia depict sacrifices from the Old Testament: the story of Abraham and Melchizedek, and the Sacrifice of Isaac; the story of Moses and the Burning Bush, Jeremiah and Isaiah, representatives of the twelve tribes of Israel, and the story of Abel and Cain. A pair of angels, holding a medallion with a cross, crowns each lunette. On the side walls the corners, next to the mullioned windows, have mosaics of the Four Evangelists, under their symbols (angel, lion, ox and eagle), and dressed in white. Especially the portrayal of the lion is remarkable in its ferocity.

The cross-ribbed vault in the presbytery is richly ornamented with mosaic festoons of leaves, fruit and flowers, converging on a crown encircling the Lamb of God. The crown is supported by four angels, and every surface is covered with a profusion of flowers, stars, birds and animals, including many peacocks. Above the arch, on both sides, two angels hold a disc and beside them a representation of the cities of Jerusalem and Bethlehem. They symbolize the human race (Jerusalem representing the Jews, and Bethlehem the Gentiles).

All these mosaics are executed in the Hellenistic-Roman tradition, lively and imaginative, with rich colors and a certain perspective and with a vivid depiction of the landscape, plants and birds. They were finished when Ravenna was still under Gothic rule. The apse is flanked by two chapels, the prothesis and the diaconicon, typical for Byzantine architecture.

Inside, the intrados of the great triumphal arch is decorated with fifteen mosaic medallions, depicting Jesus Christ, the twelve Apostles and Saint Gervasius and Saint Protasius, the sons of Saint Vitale. The theophany was begun in 525 under bishop Ecclesius. It has a great gold fascia with twining flowers, birds, and horns of plenty. Jesus Christ appears, seated on a blue globe in the summit of the vault, robed in purple, with his right hand offering the martyr's crown to Saint Vitale. On the left, Bishop Ecclesius offers a model of the church.

Justinian and Theodora panels:

At the foot of the apse side walls are two famous mosaic panels, completed in 547. On the right is a mosaic depicting the East Roman Emperor Justinian I, clad in Tyrian purple with a golden halo, standing next to court officials, Bishop Maximian, palatinae guards and deacons. The halo around his head gives him the same aspect as Christ in the dome of the apse, but is part of the tradition of rendering the imperial family with haloes describe by Ernst Kantorowicz in the King's Two Bodies. Justinian himself stands in the middle, with soldiers on his right and clergy on his left, emphasizing that Justinian is the leader of both church and state of his empire. The later insertion of the Bishop Maximian's name above his head suggests that the mosaic may have been modified in 547, replacing the representation of the prior bishop with that of the Maximian.

The gold background of the mosaic shows that Justinian and his entourage are inside the church. The figures are placed in a V shape; Justinian is placed in the front and in the middle to show his importance with Bishop Maximian on his left and lesser individuals being placed behind them. This placement can be seen through the overlapping feet of the individuals present in the mosaic.

Another panel shows Empress Theodora solemn and formal, with golden halo, crown and jewels, and a group of court women as well as eunuchs. The Empress holds the Eucharistic vessel for wine, and her panel differs from that of Justinian in having a more complex background, with a fountain, cupola, and lavish hangings.

The Mausoleum of Galla Placidia.

It was listed with seven other structures in Ravenna in the World Heritage List in 1996. The UNESCO experts describe it as "the earliest and best preserved of all mosaic monuments, and at the same time one of the most artistically perfect".

Ceiling:

The building was formerly the oratory of the Church of the Holy Cross and now contains three sarcophagi. The largest sarcophagus was thought to contain the remains of Galla Placidia (died 450), daughter of the Roman Emperor Theodosius I. Her embalmed body was reportedly deposited there in a sitting position, clothed with the imperial mantle. In 1577, however, the contents of the sarcophagus were accidentally burned. The sarcophagus to the right is attributed to Galla's son, Emperor Valentinian III, or to her brother, Emperor Honorius. The one on the left is attributed to her husband, Emperor Constantius III.

The building is not currently used as a mausoleum. Its original purpose is unknown. The most common story is that the structure was built by Galla Placidia, who was a well-known patron of the arts, to be used as a mausoleum for her and her family. There seems to be no evidence to prove or disprove Galla's connection to the building. The mausoleum was once connected to the narthex of Santa Croce, the church for the imperial palace, built in 417 but now in ruins. Santa Croce was one of the first buildings commissioned by Galla. The floor has been raised by five feet since the fifth century in order to remain above the rising water along the upper Adriatic coast.

Architecture and interior art, Ceiling mosaic Garden of Eden:

Mosaics cover the walls of the vault, the lunettes and the cupola. The iconographic themes developed in the decorations represent the victory of eternal life over death. The mausoleum is laid out in a cruciform floor plan, with a central dome on pendentives and barrel vaults over the four transepts. The exterior of the dome is enclosed in a square tower that rises above the gabled lateral wings. The brick surface is set with narrow mortar joints and decorated with blind arcades.

The interior of the mausoleum is covered with rich Byzantine mosaics, and light enters through alabaster window panels. The inside contains two famous mosaic lunettes, and the rest of the interior is filled with mosaics of Christian and Apocalyptic symbols. The central bay's upper walls are decorated with four pairs of apostles, including St. Peter and St. Paul, acclaiming a giant gold cross in the center of the dome against a blue sky of stars. Symbols of the four evangelists float among the clouds. The other four apostles appear in the barrel vaults of the transepts.

The lunette over the north entrance shows a mosaic of Christ as the Good Shepherd tending his flocks. He holds an imperial staff joined to the Christian cross, symbolizing the combined earthly and heavenly domains. The lunette over the south wall is thought to depict St. Lawrence standing next to a flaming gridiron. On the opposite side of the gridiron a bookcase is shown with four books, each inscribed with the name of an evangelist.

The art historian Gillian Mackie argues that this panel represents the Spanish St. Vincent of Saragossa rather than the Italian St. Lawrence.[2] Mackie cites Galla's connection to Spain; in addition, St. Vincent was martyred by drowning at sea, and Galla and her children had been delivered from shipwreck. The panel seems to be an illustration of the poem about St. Vincent in Prudentius's fifth century Passio Sancti Vincent Martyris. In the poem St. Vincent is ordered to disclose his sacred books to be burned. This explains the cupboard containing the Gospels, which has no satisfactory explanation in the story of St. Lawrence.

Good Shepherd Mosaic:

The Lunette of Christ as Good Shepherd over the north entrance is representative of Christian art at this time period in late antiquity. Christ is being depicted as more regal than prior depictions of him as good shepherd. Rather than carrying a lamb over his shoulder, Jesus sits amongst his flock, haloed and robed in gold and purple. The mosaic represents a transition period between the naturalistic depictions of the classical period in art history and the stylized representations of the medieval period. The forms still have three-dimensional bulk, but the shading such as in the folds of the robes is less refined than in the past, and figures are not very grounded. Elements of realism have been sacrificed for a focus on the spiritual elements.

The mausoleum is reputed to have inspired American songwriter Cole Porter to compose "Night and Day" while on a 1920s visit

The Baptistery of Neon

The most ancient monument remaining in the city, it was partly erected on the site of a Roman bath. It is also called the Orthodox Baptistery to distinguish it from the Arian Baptistery constructed on behest of Ostrogothic King Theodoric some 50 years later.

The octagonal brick structure was erected by Bishop Ursus at the end of the 4th or beginning of the 5th century, as part of his great Basilica (destroyed in 1734). The baptistery was finished by Bishop Neon at the end of the 5th century, at which time the mosaic decorations were added. The original floor is now some 3 metres underground, so the proper structure and extent of the building can no longer be seen. The octagonal design of the building, employed in virtually all Early Christian baptisteries, symbolizes the seven days of the week plus the Day of the Resurrection and Eternal Life.

The ceiling mosaic depicts John the Baptist baptizing Jesus (depicted with beard) standing waist high in the Jordan River. To one side stands the personification of the Jordan river, with a reed in one hand and a garment in the other. A procession of the twelve apostles proceeds around the center mosaic in two directions, ending with Saint Peter meeting Saint Paul.

The ceiling mosaic in the Baptistry of Neon

The Baptistry is one of the eight structures in Ravenna registered as UNESCO World Heritage Sites. According to the ICOMOS evaluation of this patrimony, "this is the finest and most complete surviving example of the early Christian baptistery" which "retains the fluidity in representation of the human figure derived from Greco-Roman art".

The Archbishop's Chapel (or Archiepiscopal Chapel) is a chapel on the first floor of the bishops' palace, the smallest of the famous mosaic sites of the city. It is a private oratory of Trinitarian bishops dating from the turn of the 6th century. Although commonly attributed to St. Peter Chrysologus, Archbishop of Ravenna from 433–450, the chapel was actually built by Peter II shortly after he became archbishop in 495. The mosaics date from the original construction, or soon after.

Description

The tiny cruciform chapel is currently dedicated to Saint Andrew, although the original dedication was to the Saviour, as evidenced by a lunette over the vestibule door representing Christ treading on the beasts, dressed as a general or victorious Emperor. The lower parts of the walls are lined with marble slabs, while the rest of the interior used to be covered with rich, tapestry-like mosaics, as the vault still is. Some parts of these survive, while others were substituted with tempera paintings by Luca Longhi in the 16th century.

Significance

According to the ICOMOS evaluation of this World Heritage Site, "the significance of this property is the fact that it is the only Early Christian private oratory that has survived to the present day. Its iconography is also important by virtue of its strongly anti-Arian symbolism".

​The Basilica of Sant' Apollinare Nuovo was erected by the Ostrogothic King Theodoric the Great as his palace chapel during the first quarter of the 6th century (as attested to in the Liber Pontificalis). This Arian church was originally dedicated in 504 AD to "Christ the Redeemer". It was reconsecrated in 561 AD, under the rule of the Byzantine emperor Justinian I, under the new name "Sanctus Martinus in Coelo Aureo" ("Saint Martin in Golden Heaven"). Suppressing the Arian church, the church was dedicated to Saint Martin of Tours, a foe of Arianism. According to legend, Pope Gregory the Great ordered that the mosaics in the church be blackened, as their golden glory distracted worshipers from their prayers. The basilica was renamed again in 856 AD when relics of Saint Apollinaris were transferred from the Basilica of Sant'Apollinare in Classe because of the threat posed by frequent raids of pirates from the Adriatic Sea. Its apse and atrium underwent modernization at various times, beginning in the 6th century with the destruction of mosaics whose themes were too overtly Arian or which expressed the king's glory, but the mosaics of the lateral walls, twenty-four columns with simplified Corinthian capitals, and an Ambo are preserved. On some columns, images of arms and hands can be seen, which are parts of figures once representing praying Goths and Theodoric's court, deleted in Byzantine times. Renovations (and alterations) were done to the mosaics in the mid-19th century by Felice Kibel. The present apse is a reconstruction after being damaged during World War I. On the upper band of the left lateral wall are 13 small mosaics, depicting Jesus' miracles and parables; and on the right wall are 13 mosaics depicting the Passion and Resurrection.​     However, the flagellation and crucifixion are lacking. They describe the parts of the Bible that were read aloud in the church during Lent under the rule of Theodoric the Great. On the left, Jesus is always depicted as young, beardless man, dressed as a Roman Emperor. On the right, Jesus is depicted with a beard. For the Arians, this emphasised that Jesus grew older and became a "man of sorrows", as spoken of by the prophet Isaiah. These mosaics are separated by decorative mosaic panels depicting a shell-shaped niche with a tapestry, cross, and two doves. These mosaics were executed by at least two artists. Mosaic on the right side wall of the nave: palace of Theodoric. Remains of hands are still visible in the columns. The next row of mosaics are a scheme of haloed saints, prophets and evangelists, sixteen on each side. The figures are executed in a Hellenistic-Roman tradition and show a certain individuality of expression as compared to the other figures in the basilica. Each individual depicted holds a book, in either scroll or codex format, and, like many of the other figures throughout the basilica, each of their robes has a mark or symbol in it. These mosaics alternate with windows. They were executed in the time of Theodoric. The row below contains large mosaics in Byzantine style, lacking any individuality, having all identical expressions. These were executed about 50 years after the time of bishop Agnellus, when the church had already become an orthodox church. To the left is a procession of the 22 Virgins of the Byzantine period, led by the Three Magi, moving from the city of Classe towards the group of the Madonna and Child surrounded by four angels. (The Magi in this mosaic are named Balthasar, Melchior and Gaspar; this is thought to be the earliest example of these three names being assigned to the Magi in Christian art.) To the right is a similar procession of 26 Martyrs, led by Saint Martin and including Saint Apollinaris, moving from the Palace of Theodoric towards a group representing Christ enthroned amid four angels. This lower band, containing a schematic representation of the Palace of Theoderic on the right wall and the port of Classe with three ships on the left wall, gives us a certain idea of the architecture in Ravenna during the time of Theodoric. In another part of the church there is a rough mosaic containing the portrait of the Emperor Justinian. The entrance of the church is preceded by a marble portico built in the 16th century. Next to the church, on the right side of the portico, stands a round bell tower dating from the 9th or 10th century. When the UNESCO inscribed the church on the World Heritage List, its experts pointed out that "both the exterior and interior of the basilica graphically illustrate the fusion between the western and eastern styles characteristic of the late 5th to early 6th century. This is one of the most important buildings from the period of crucial cultural significance in European religious art". Some art historians claim that one of the mosaics contains the first depiction of Satan in western art. In the mosaic, a blue angel appears to the left hand side of Jesus behind three goats (mentioned in St Matthew's account of Judgement Day).

The Arian Baptistry is a Christian baptismal building that was erected by the Ostrogothic King Theodoric the Great between the end of the 5th century and the beginning of the 6th century A.D., at the same time as the Basilica of Sant' Apollinare Nuovo.

Theodoric was an Arian Christian and decided to let the Goths (Arians) and the Orthodox Chalcedonian Christians live together but separately, and so there were separate neighborhoods and separate religious buildings.

Near his palace, the king commissioned an Arian cathedral, now called the Church of Spirito Santo, but originally named Hagia Anastasis (Holy Resurrection). It was re-consecrated as the Chalcedonian cathedral of Saint Teodoro (soldier and martyr of Amasea in Pontus) in 526 AD. Little remains of the original church after its reconstruction in 1543; some historians speculate that the original mosaics were lost over a thousand years earlier during its Catholic reconstruction due to Arian themes. During this same period, Theodoric also had the baptistry built, today referred to as "of the Arians" in order to distinguish it from the Baptistry of Neon (of the Orthodox) which is about one century older.

The Baptistry is octagonal in shape with some little apses and arched openings near the top. Along the external perimeter there was once a walkway that stopped at the eastern apse. Clearly, the building was once part of a larger complex. Inside are four niches and a dome with mosaics, depicting the baptism of Jesus by Saint John the Baptist. Jesus is shown as a beardless, half-submerged in the Jordan. John the Baptist is wearing a leopard skin. On the left stands a white-haired, old man in a green cloak, holding a leather bag. He is the personification of the river Jordan. Above, the Holy Spirit in the form of a dove sprays lustral water from its beak.

Below, a procession of the Apostles, led in separate directions by Saint Peter and Saint Paul circle the dome, meeting at a throne with a jeweled crucifix resting on a purple cushion.

​

It took the artists several years to complete these mosaics, as can be clearly seen from the different colors of the stones used to depict the grass at the feet of the apostles. The designs are quite simple, but the excessive use of a gold background should be noted, as it was typically used in this era to infuse these simple scenes with an ethereal glow.

The entire composition is remarkably similar to that of the Orthodox Baptistry of Neon. The walls are bare, but were not always so. During archaeological investigations, some 170 kilograms of tessera were found on the floor. Due to the lack of Arian references, it is believed that the artists who created the mosaics were Orthodox Christians, as the Ostrogoths were predominantly goldsmiths and not mosaic artists.

In 565, after the condemnation of the Arian sect, this small octagonal brick structure was converted into a Chalcedonian oratory named Santa Maria. Eastern-Rite monks added a monastery during the period of the Exarchate of Ravenna and further dedicated the structure to Saint Maria in Cosmedin. Around the year 1700, the structure passed into private hands, and in 1914 it was acquired by the Italian government. The Allied bombardment of World War II helped clear away other structures which had encroached on it from all sides, enabling researchers to view the details of its exterior for the first time. As with other monuments in Ravenna, the original floor is now some 2.3 meters underground.
