St Mark's Basilica

San Marco di Venezia, as seen from the Piazza San Marco

The Patriarchal Cathedral Basilica of Saint Mark (officially known in Italian as the Basilica Cattedrale Patriarcale di San Marco and commonly known as Saint Mark's Basilica) is the cathedral church of the Roman Catholic Archdiocese of Venice, northern Italy. It is the most famous of the city's churches and one of the best known examples of Byzantine architecture. It lies at the eastern end of the Piazza San Marco, adjacent and connected to the Doge's Palace. Originally it was the chapel of the Doge, and has only been the city's cathedral since 1807, when it became the seat of the Patriarch of Venice, archbishop of the Roman Catholic Archdiocese of Venice, formerly at San Pietro di Castello. For its opulent design, gilded Byzantine mosaics, and its status as a symbol of Venetian wealth and power, from the 11th century on the building has been known by the nickname Chiesa d'Oro (Church of gold)

History

The building

The first St Mark's was a temporary building in the Doge's Palace, constructed in 828, when Venetian merchants stole the supposed relics of Mark the Evangelist from Alexandria. This was replaced by a new church on its present site in 832; from the same century dates the first St Mark's Campanile (bell tower). The new church was burned in a rebellion in 976, rebuilt in 978 and again to form the basis of the present basilica since 1063. The basilica was consecrated in 1094, the same year in which the body of Saint Mark was supposedly rediscovered in a pillar by Vitale Faliero, doge at the time. The building also incorporates a low tower (now housing St Mark’s Treasure), believed by some to have been part of the original Doge's Palace. Within the first half of the 13th century the narthex and the new façade were constructed, most of the mosaics were completed and the domes were covered with higher wooden, lead-covered domes in order to blend in with the Gothic architecture of the redesigned Doge's Palace.

The completion

While the basic structure of the building has been much altered, its decoration changed greatly over time. The succeeding centuries, especially the fourteenth, all contributed to its adornment, and seldom did a Venetian vessel return from the Orient without bringing a column, capitals, or friezes, taken from some ancient building, to add to the fabric of the basilica. Gradually, the exterior brickwork became covered with various marbles and carvings, some much older than the building itself (see Four Tetrarchs, below). The last interventions concerned Baptistery and St Isidor’s Chapel (1300s), the carvings on the upper profile of the facade and the Sacristy (1400s), the Zen Chapel (1500s). This cathedral is a prime example of Gothic architecture due to the fact of it's looks from a distance. It takes on the appearance of what would be in the classification of Gothic.

The key figures

As a "State church", until 1807, the basilica was not subject to the bishop (patriarch since 1451), whose cathedral was San Pietro di Castello. The doge himself appointed for celebrations a special clergy led by the primicerio. The procurators’, an important organ of the Republic of Venice, were in charge of administration; their seats were the Procuratie, in St Mark’s Square. All building and restoring works were directed by the protos: great architects such as Jacopo Sansovino and Baldassarre Longhena had this title. Procurators and proto still exist and accomplish the same tasks for the Patriarchate.

Exterior

The exterior of the basilica is divided in three registers: lower, upper, and domes. In the lower register of the façade five round-arched portals, enveloped by polychrome marble columns, open into the narthex through bronze-fashioned doors. Above the central door round three bas-relief cycles of Romanesque art. The external cycle frames a 19th century gilded mosaic (Last Judgment) that replaced a damaged one with the same subject (during the centuries many mosaics had to be replaced inside and outside the basilica, but subjects were never changed). Mosaics about St Mark relics’ stories are in the lunettes of the lateral portals; the first on the left is the only one in the façade preserved from the 13th century. In the upper register, from the top of ogee arches, statues of Theological and Cardinal Virtues, four Warrior Saints and St Mark watch over the city. Above the large central window of the façade, under St Mark, the Winged Lion (his symbol) holds the book quoting “Pax Tibi Marce Evangelista Meus” (Peace to you Mark my evangelist) . In the lunettes of the lateral ogee arches are four gilded mosaics renewed in the 17th century. In the center of the balcony the Greek Horses face the square.

The Greek Horses

The Horses of Saint Mark were installed on the basilica in about 1254. They date to Classical Antiquity; by some accounts they once adorned the Arch of Trajan. The horses were long displayed at the Hippodrome of Constantinople, and in 1204 Doge Enrico Dandolo sent them back to Venice as part of the loot sacked from Constantinople in the Fourth Crusade. They were taken to Paris by Napoleon in 1797 but returned to Venice in 1815. After a long restoration, since the 1990s they have been kept in St Mark’s Museum (inside the basilica). The horses now on the facade of the cathedral are bronze replicas.

The Tetrarchs

The Tetrarchs. ( 3D image available)In an attempt to stabilise the Roman Empire after the crisis of the third century, the Emperor Diocletian imposed a new Imperial office structure: a four co-emperor ruling plan called The Tetrarchy. This porphyry statue represents the inter-dependence of the four rulers. It was taken from Constantinople, during the Fourth Crusade in 1204, and set into the south-west corner of the basilica (the above mentioned low tower) at the level of the Piazza San Marco. The missing foot of one of the figures was discovered in Istanbul in the 1960s, where it is still on display.

Narthex

Originally, the narthex embraced the western arm of the basilica on the three sides; later the southern part was closed to obtain the Baptistery (14th century) and the Zen Chapel (16th century). The narthex prepare the visitors’ eyes to the suffused atmosphere of the gilded interior, just like the Old Testament stories represented in its mosaic ceiling prepare to the Gospel of the basilica’s. The main subjects are Genesis and the life of Noah, Abraham, Joseph, Moses. Beside the main portal remain the Evangelists, 11th century mosaics that decorated the entrance to St Mark’s even before the narthex was built.

Interior

The interior is based on a Greek cross, with each arm divided in three naves and emphasized by a dome of its own. This is based on Justinian's Basilica of the Apostles in Constantinople. The marble floor (12th century, but underwent many restorations) is entirely tessellated in geometric patterns and animal designs. The techniques used were opus sectile and opus tessellatum. The lower register of walls and pillars is completely covered with polychrome marble slabs. The transition between the lower and the upper register is delimited all around the basilica by passageways which largely substituted the former galleries.

The presbytery

The eastern arm has a raised presbytery with a crypt beneath. The presbytery is separated by an altar screen formed by eight red marble columns crowned with a high Crucifix and statues by Pier Paolo and Jacobello Dalle Masegne, masterpiece of Gothic sculpture (late 14th century). Behind the screen, marble banisters with Sansovino's bronze statues of the Evangelists and Paliari's of the Four Doctors mark the access to the high altar, which contains St Mark’s relics. Above the high altar is a canopy (“ciborium”) on columns decorated with remarkable relieves; the altarpiece is the famous Pala d'Oro (Golden Pall) ,a masterpiece of Byzantine craftsmanship, originally designed for an antependium. The choir stalls are embellished with inlaying by Fra Sebastiano Schiavone, and above them on both sides are three relieves by Sansovino.

Behind the presbytery are the sacristy and a 15th century church consecrated to St Theodore (the first patron saint of Venice) where is displayed a painting (Child’s Adoration) by Giovanni Battista Tiepolo.

Right transept

On the right of the screen is the platform from which the newly-elected doge appeared. In the left aisle are St Clement’s chapel and the Holy Host altar. Here is the pillar where St Mark’s relics were rediscovered in 1094, as depicted in the interesting mosaics of the right aisle (where the entrance to St Mark’s Treasure is).

Left transept
