Ghent Altarpiece in the context of "Altarpiece"

Renaissance art (1350 – 1620) is the painting, sculpture, and decorative arts of the period of European history known as the Renaissance, which emerged as a distinct style in Italy in about AD 1400, in parallel with developments which occurred in philosophy, literature, music, science, and technology. Renaissance art took as its foundation the art of Classical antiquity, perceived as the noblest of ancient traditions, but transformed that tradition by absorbing recent developments in the art of Northern Europe and by applying contemporary scientific knowledge. Along with Renaissance humanist philosophy, it spread throughout Europe, affecting both artists and their patrons with the development of new techniques and new artistic sensibilities. For art historians, Renaissance art marks the transition of Europe from the medieval period to the Early Modern age.

The body of art, including painting, sculpture, architecture, music and literature identified as "Renaissance art" was primarily produced during the 14th, 15th, and 16th centuries in Europe under the combined influences of an increased awareness of nature, a revival of classical learning, and a more individualistic view of man. Scholars no longer believe that the Renaissance marked an abrupt break with medieval values, as is suggested by the French word renaissance, literally meaning "rebirth". In many parts of Europe, Early Renaissance art was created in parallel with Late Medieval art.

The magisterium of the Catholic Church is the church's authority or office to give authentic interpretation of the word of God, "whether in its written form or in the form of Tradition". According to the 1992 Catechism of the Catholic Church, the task of interpretation is vested uniquely in the Pope and the bishops, though the concept has a complex history of development. Scripture and Tradition "make up a single sacred deposit of the Word of God, which is entrusted to the Church", and the magisterium is not independent of this, since "all that it proposes for belief as being divinely revealed is derived from this single deposit of faith."

A panel painting is a painting made on a flat panel of wood, either a single piece or a number of pieces joined together. Until canvas became the more popular support medium in the 16th century, panel painting was the normal method, when not painting directly onto a wall (fresco) or on vellum (used for miniatures in illuminated manuscripts). Wood panels were also used for mounting vellum paintings.

The miles Christianus 'Christian soldier' or miles Christi 'soldier of Christ' is a Christian allegory based on New Testament military metaphors, especially the Armor of God metaphor of military equipment standing for Christian virtues and on certain passages of the Old Testament from the Latin Vulgate. The plural of Latin miles 'soldier' is milites or the collective militia.

By the 5th century, the Church had started to develop doctrines that allowed for Christian participation in battle, though this was limited by a requirement that the fighting must be undertaken to convert infidels or spread the glory of Christ. Christians were not to fight for conquest or personal glory.

Christ the King is a title of Jesus in Christianity referring to the idea of the Kingdom of God where Christ is described as being seated at the right hand of God. Many Christian denominations consider the kingly office of Christ to be one of the threefold offices: Christ is a prophet, priest, and king. The title "Christ the King" is frequently used as a name for churches, schools, seminaries, hospitals, and religious institutes.

Hubert van Eyck (Dutch pronunciation: [ˈɦybərt fɑn ˈɛik]; c. 1385/90 – 18 September 1426) was an Early Netherlandish painter and older brother of the renowned Jan van Eyck, as well as Lambert and Margareta, also painters. The absence of any single work that he can clearly be said to have completed continues to make an assessment of his achievement highly uncertain, although for centuries he had the reputation of being an outstanding founding artist of Early Netherlandish painting.

Today he is attributed to having at least begun the Ghent Altarpiece and The Three Marys at the Tomb, although both were likely completed by his brother Jan.

A polyptych (/ˈpɒlɪptɪk/ POL-ip-tik; Greek: poly- "many" and ptychē "fold") is a work of art (usually a panel painting) which is divided into sections, or panels. Some definitions restrict "polyptych" to works with more than three sections: a diptych is a two-part work of art; a triptych is a three-part work; a tetraptych or quadriptych has four parts; a pentaptych has five parts. The great majority of historical examples are paintings with religious subjects, but in the 20th century the format became popular again for portraits and other subjects, in painting, photography, and other media.

Historically, polyptychs were panel paintings that typically displayed one "central" or "main" panel that was usually the largest; the other panels are called "side" panels, or if hinged, "wings". Folding forms were much more common north of the Alps. Sometimes, as evident in the Ghent Altarpiece and Isenheim Altarpiece, the hinged panels can be varied in arrangement to show different "views" or "openings" in the piece, because the wing panels are painted with images on both sides. The wings were usually kept folded shut, showing the "closed" view, except on Sundays or feast-days, or if visitors paid the sacristan for a sight of the "open" view. The upper panels often depict static scenes, while the lower register, the predella, often depict small narrative scenes.
