Bernward Doors

Along with the Bernward Column, the doors are part of Bishop Bernward's efforts to create a cultural ascendancy for the seat of his diocese with artistic masterpieces in the context of the Renovatio imperii sought by the Ottonians. A Latin inscription on the middle crossbar produced after Bernward's death gives the year 1015 as the terminus ante quem for the creation of the doors: ==Creation and technical features==

Each leaf of the doors was cast as a single piece. Given the size (left: 472.0 x 125.0 cm, right: 472.0 x 114.5 cm, maximum thickness c. 3.5-4.5 cm) and enormous weight (both c. 1.85 tonnes) of the doors, this is a great achievement for its time. The raw material for the casting was Gunmetal, which consisted predominantly of copper (above 80%) with roughly equal parts of lead, tin, and zinc. To date material analysis has not been able to show which ore deposit the metal came from, though the ironworks at Rammelsberg near Goslar has been ruled out. Like their predecessors, the Wolfstür (Wolf's door) of the Aachen Cathedral and the Marktportal (Market Portal) of the Mainz Cathedral, the Bernward Doors were manufactured using the Lost-wax process, which puts exceptional demands on the workers of the casting workshop, since the mold can only be used once. The individual scenes of the doors were carved from massive wax or tallow tablets by modellers and then combined, supported by an iron frame, which is probably how the slight irregularities in the bands which divide the individual scenes came about. Even the doorknockers in the form of grotesque lion's heads with rings of grace in their mouths were included in the original mold rather than being soldered on later. Technical analysis has shown that the mold was stood on the long side and filled with bronze, so that the molten metal would spread evenly; investigation has found cooling cracks in the metal. The result of this process was probably still rather rough, covered in metal bumps from the pipes in the mold through which the metal was poured in and through which air escaped and it would have had to have been worked over and polished up in great detail. ==Iconography==

The Bernward Doors depict scenes from the Book of Genesis (left door) arranged in parallel to scenes from the Gospels (right door). The scenes are organized based on the principle that Adam and Christ mirror each other - with Christ's sacrificial death redeeming Adam's sin. The left door depicts the increasing estrangement of humanity from God from top to bottom: the Creation, the Fall, Cain's murder of Abel. The right door shows the redemptive work of Christ from bottom to top: the Annunciation and Nativity, the Passion, the Resurrection). The depictions of the right door, in which the birth and childhood of Jesus are followed immediately by his passion and resurrection, are complemented thematically by the depiction of his life and ministry on the Bernward Column, which was probably also donated by Bernward, and stood in the east choir of St. Michael's until the eighteenth century. In some cases, several events which chronologically occur one after another are depicted in a single panel, leading to an odd sense of multiplicity. This was an artistic convention of the time, much used in illuminated manuscripts. So for example, Adam appears twice in the scene of his awakening by God the Father. Left door • Top panel: God creates Adam. Adam after the creation. • Second panel: Adam and Eve are introduced • Third panel: The fall • Fourth panel: God interrogates Adam and Eve • Fifth panel: Expulsion from paradise • Sixth panel: Life on earth (door handle) • Seventh panel: Cain and Abel make their offerings to God • Eighth panel: Cain kills Abel Right door • Top panel: Noli me tangere; ascension of Christ into heaven • Second panel: The women at the tomb • Third panel: The crucifixion • Fourth panel: Christ appears before Pilate and Herod • Fifth panel: The child Jesus is brought to the Temple • Sixth panel: The gifts of the Wise Men (door handle) • Seventh panel: The birth of Christ • Eighth panel: The annunciation to Mary Typological correlation To understand the parallelism between the panels of the left and right doors, one must enter the medieval mindset, with its typological reading of the Old Testament according to the revelation of the New Testament (concordantia veteris et novi testamenti - harmony of the Old and New Testament). The typological concordances presented on the Bernward doors are based for the most part on the theological writings of the Church Fathers, especially St. Augustine: == Style and composition ==

The doors are made up of a number of framed panels; unlike the Roman originals, however, the design at Hildesheim is not their design, but probably an imitation of the ancient Roman examples. Moreover, the impact of the frames is significantly reduced in favour of the figural scenes by their narrowness and the flat relief, so that they appear like the images of a contemporary illustrated manuscript, like the Codex Aureus of Echternach. Composition of the scenes The composition of the individual scenes is simple and effective. In contrast to the dramatic depictions of Carolingian art, the artists avoided richly decorated backgrounds. The scenery, consisting of plants (especially on the left leaf) and architectural elements (mostly on the right leaf) are depicted in low relief and kept to a minimum. They are only there at all where they are necessary for comprehension of the scene or for compositional reasons. Instead, vast empty spaces provide negative space around the figures in the panels, to great effect. identified the empty space as an "effective space of corresponding gestures." With their movement and individual gestures, each figure interacts with others – none of the figures can be understood on their own, independent of their counterparts, without losing their meaning. Figures As usual in medieval art, the figures are not individualized, but repeat a few stylised types. They have the disproportionately large, oval faces which are characteristic of Pre-Romanesque sculpture. Their very large, almond-shaped eyes sit in flat sockets with sharply delineated eyebrows. The hair is composed of parallel strands from a central parting. Nevertheless, the facial expressions of some figures are very individuated and match the figures' gestures. Especially relevant in this respect is the figure of Cain who looks up to the Hand of God in heaven with fearful, terror-stricken eyes and pulls his cloak tight around his body. A progressive feature of the figures on the Bernward Doors is their style of relief: the figures do not extend a uniform distance from the background, but 'lean' out from it, so that when seen side on they almost give the impression of "roses on a trellis, with nodding heads." A particular apt example of this is the figure of Mary with the baby Jesus in the depiction of the Adoration of the Magi: while her lower body is still in low relief, her upper body and Christ project out further, and finally Mary's shoulders and head are cast in the round. This unusual style was used for artistic reasons, not because of technical limitations. Identity of the artist Unlike, for example, the Market Portal of the Mainz Cathedral, the identity of the artist responsible for the Bernward Doors is not preserved. As a result, older research attempted to identify a varying number of different artists on the basis of stylistic analysis of the individual panels. Rainer Kahsnitz has since put these attributions in doubt, since the differences in execution between the reliefs is so marginal that they might as easily be the result of technical requirements as different artistic styles. Probably a single artist was responsible for the creation of the Bernward Doors, with a small group of apprentices and assistants. ==Predecessors and later works==

c.1009. There are various possibilities for the model of the Hildesheim doors as panelled doors (on the Roman model) and for the material used. Outstanding examples of monumental bronzeworking of the period include the doors of the Palatine chapel (c.800) and the doors of the Marktportal of Mainz Cathedral, which Archbishop Willigis had the founder Berenger cast in 1009. However, these doors have no figural decoration, except for door handles in the shape of lion's heads on the Aachen Wolfstür. As his biographer Thangmar reported in the Vita Bernwardi, Bishop Bernward lived first in the Hostel of the Schola Francorum at the Vatican and then in the Imperial Palace on the Palatine during his stay at Rome in 1001/2. He would have had the opportunity to view the monumental bronze door at the entrance to Old St. Peter's. He probably also saw the Late Antique wooden doors of Santa Sabina with their relief cycle in which Old and New Testament scenes are arranged opposite each other in a typology. The Late Antique doors of Sant'Ambrogio in Milan are also a possible model. Franz Dibelius first pointed out the clear parallels between illumination of manuscripts in the time of Charles the Bald and the composition of the images and figures of the left door. Some scenes of the Bernward Doors, e.g. the creation of Adam or the earthly life of Adam and Eve are arranged nearly identically to the so-called Moutier-Grandval Bible (London, British Library, Ms Add. 10546). Significantly, this Late Carolingian manuscript came from Tours, where Bernward stayed in 1006, returning to Hildesheim a year later with expensive relics for the silver Cross of Bernward. Close parallels can also be seen with other significant manuscripts of the ninth century, such as the c.800 Alcuin Bible (Bamberg State Library, Msc.Bibl.1) and the Bible of Saint Paul Outside the Walls, created in 877 at Corbie Abbey (Rom, Abbazia di S. Paolo fuori le mura). That Bernward brought copies of famous Frankish bibles back from his travels is definitely not certain, but possible. The ivory cover of the Stammheim Missal (de), in which Alcuin presents a book to St. Martin of Tours, as the patron saint of his cloister, could derive from a bible of Tours acquired by Bernward. Rudolf Wesenberg drew further iconographic and stylistic connections, but with traditional frescos in St. Paul beyond the Walls and Old St. Peter's which Bernward could have seen while in Rome. A range of further medieval bronze doors followed the Bernward Doors, but they have no clear connection with Hildesheim. The idea of casting the whole door from a single mold did not catch on - the most important metal doors are composed of a wooden frame with bronze panels inserted. One of the Gniezno Doors, made for Poland in about 1175, is also a single piece casting, but artistically much less sophisticated. This apparently proved too difficult, and for the other door 24 cast panels were soldered together. For the western doors of St. Paulus in Worms, in 1881, the sculptor created a detailed replica of the Bernward Doors; unlike the original, these were made of cast iron and for reasons of space, the two highest images (the creation of Adam and the Ascension of Christ!) were not included. The Renaissance Florence Baptistery doors are the most famous doors in the tradition Bernward played an important role in reviving. ==Original location dispute==

The "Angelic temple" named in the inscription has been identified by some scholars as Bernward's sepulchral church of the archangel St. Michael. According to them, the doors were originally hung in the south aisle (perhaps as two separate doors), in the cloisters, or in no longer extant westwork and were transferred to the Cathedral in 1035 for the new western entrance which Wolfhere (de) reports that Bishop Gotthard had made in his biography, ''''. A combination of the previous hypothesis with the original location of the doors is provided by Wesenberg. Latterly, Bernhard Bruns attempted to locate the original location of the doors at St. Michael's by their iconography. The excavations carried out during renovations in 2006 have now demonstrated that St. Michael's never had a westwork. But the installation of the doors on the south aisle has also come into question, since foundation remains of a narthex were found there, next to the western stairway tower. Recent research in religious history now demonstrates templum angelicum was a liturgical form for a church dedicated to St. Michael. Other scholars argue that the doors were in Hildesheim Cathedral from the beginning, in the westwork which is otherwise held to have first been built in 1035. Although the current west gallery has only been there since 1035, they argue that Bernward had already laid down a west building here, whose shape and appearance can no longer be reconstructed with confidence. Either Bernward would have had the previous west choir and the crypt underneath truncated to create space for a vestibule, where the Bernward Doors might have been installed or he would have had the west choir extended and installed the doors in the entrance to a chapel, which would have been built in front of the apse. Only a few hints in the foundations support the idea of a Bernwardian west gallery in the cathedral and they allow no more detailed conjecture about its layout. Literary sources offer no evidence for Bernward's construction work on the cathedral. If the doors were located in the western part of the building, they would have had to have been moved pretty soon after, since the cathedral was drastically altered by his successors Gotthard, Azelin and Hezilo. A later period of drastic reconstruction of the western part of the building occurred in 1842–50. Later, the westwork was largely rebuilt after taking severe damage in an air raid during the Second World War. The modern plan of Wilhelm Fricke (which is not uncontroversial) is not based on the alleged layout of Bernward's time, but on the westwork of Minden Cathedral and the alleged appearance of Hildesheim cathedral's westwork under Bishop Hezilo (1054–61). The leaves of the door escaped damage in the air raid of Hildesheim on 22 March 1945 only because they had been removed (at the initiative of the cathedral chapter) almost three years earlier, along with many other artworks of the cathedral. The leaves of the doors were taken to the so-called Kehrwieder wall in the southeast of the old city, where they spent the war underground. Since the doors weigh several tonnes, they had to be transported lying longwise in a stable scaffold by two teams of horses. ==Liturgical significance==

According to the Hildesheim cathedral ordinarium of 1473 "On Ash Wednesday in the medium monasterii, the bishop performed the ash sprinkling and the expulsion of public penitents through the southwestern church doors. After that they departed from the cathedral barefoot with the clergy through the large bronze doors and after walking about they went back in through the same doors." The rite of the expulsion of the penitents in Lent derives its meaning from the banishment of Adam and Eve from Paradise shown on the doors. "The images of the left leaf with the creation of humanity, the fall of man and the story of Cain and Abel corresponds to the breviary reading (Genesis 1-5.5) on Septuagesima Sunday and the following week, which begins the pre-Lenten period." Thus in its original location, the door probably also served for the education of the penitents, who were restricted to the vestibule (Narthex or "Paradise") of the churchbuilding during Lent. ==Bibliography==
