Andrea Pozzo
–
Andrea Pozzo was an Italian Jesuit Brother, Baroque painter and architect, decorator, stage designer, and art theoretician. Pozzo was best known for his grandiose frescoes using illusionistic technique called quadratura, in which architecture and his masterpiece is the nave ceiling of the Church of SantIgnazio in Rome. Through his techniques, he has one of the most remarkable figures of the Baroque period. He is also noted for the plans of the Ljubljana Cathedral, inspired by the designs of the Jesuit churches Il Gesù. Born in Trento, he did his Humanities at the local Jesuit High School, showing artistic inclinations he was sent by his father to work with an artist, Pozzo was then 17 years old. From aspects of his early style this initial artistic training came probably from Palma il Giovane, after three years he passed under the guidance of another unidentified painter from the workshop of Andrea Sacchi who appears to have taught him the techniques of Roman High Baroque. He would later travel to Como and Milan, on 25 December 1665, he entered the Jesuit Order as a lay brother. In 1668, he was assigned to the Casa Professa of San Fidele in Milan and he continued artistic training in Genoa and Venice. His early paintings attest the influence of the Lombard School, rich colour, when he painted in Genoa the Life of Jesus for the Congregazione de Mercanti, he was undoubtedly inspired by Peter Paul Rubens. Pozzos artistic activity was related to the new Orders enormous artistic needs and he was frequently employed by the Jesuits to decorate churches and buildings such as their churches of Modena, Bologna and Arezzo. In 1676, he decorated the interior of San Francis Xavier church in Mondovì and this was his first large fresco. In Turin Pozzo painted the ceiling of the Jesuit church of SS, the frescoes gradually deteriorated through water infiltration. They were replaced in 1844 by new paintings by Luigi Vacca, only fragments of the original frescoes survive. In 1681, Pozzo was called to Rome by Giovanni Paolo Oliva, among others, Pozzo worked for Livio Odescalchi, the powerful nephew of the pope, Innocent XI. His first Roman frescoes were in the corridor linking the Church of the Gesù to the rooms where St. Ignatius had lived and his trompe loeil architecture and paintings depicting the Saints life for the Camere di San Ignazio, blended well with already existing paintings by Giacomo Borgognone. For several generations, they set the standard for the decoration of Late Baroque ceiling frescos throughhout Catholic Europe, compare this work to Gaullis masterpiece in the other major Jesuit church in Rome, Il Gesù. The church of SantIgnazio remained unfinished with bare ceilings even after its consecration in 1642, disputes with the original donors, the Ludovisi, prevented the completion of the planned dome. Pozzo expediently proposed to make an illusionistic dome, when viewed from inside and it was impressive to viewers, but controversial, some feared the canvas would soon darken

Renaissance art
–
Renaissance art, with Renaissance Humanist philosophy, spread throughout Europe, affecting both artists and their patrons with the development of new techniques and new artistic sensibilities. Renaissance art marks the transition of Europe from the period to the Early Modern age. In many parts of Europe, Early Renaissance art was created in parallel with Late Medieval art, the following list presents a summary, dealt with more fully in the main articles that are cited above. Classical texts, lost to European scholars for centuries, became available and these included Philosophy, Prose, Poetry, Drama, Science, a thesis on the Arts and Early Christian Theology. Simultaneously, Europe gained access to advanced mathematics which had its provenance in the works of Islamic scholars, the advent of movable type printing in the 15th century meant that ideas could be disseminated easily, and an increasing number of books were written for a broad public. The establishment of the Medici Bank and the subsequent trade it generated brought unprecedented wealth to a single Italian city, cosimo de Medici set a new standard for patronage of the arts, not associated with the church or monarchy. Humanist philosophy meant that mans relationship with humanity, the universe, a revived interest in the Classics brought about the first archaeological study of Roman remains by the architect Brunelleschi and sculptor Donatello. A similar heritage of artistic achievement occurred in Venice through the talented Bellini family, their influential inlaw Mantegna, Giorgione, Titian, the publication of two treatises by Leone Battista Alberti, De Pitura,1435, and De re aedificatoria,1452. Their masterpieces are the pulpits of the Baptistery and Cathedral of Pisa, the painters of the Low Countries at this period included Jan van Eyck, his brother Hubert van Eyck, Robert Campin, Hans Memling, Rogier van der Weyden and Hugo van der Goes. Their painting developed independently of Early Italian Renaissance painting, and without the influence of a deliberate, the style of painting grew directly out of the Medieval arts of tempera painting, stained glass and book illumination. The media used was oil paint, which had long been utilised for painting leather ceremonial shields and accoutrements, because it was flexible, the earliest Netherlandish oil paintings are meticulous and detailed like tempera paintings. The material lent itself to the depiction of variations and texture. The Netherlandish painters did not approach the creation of a picture through a framework of linear perspective and they maintained a Medieval view of hierarchical proportion and religious symbolism, while delighting in a realistic treatment of material elements, both natural and man-made. Jan van Eyck, with his brother Hubert painted The Altarpiece of the Mystical Lamb and it is probable that Antonello da Messina became familiar with Van Eycks work, while in Naples or Sicily. His studies of perspective are thought to have influenced the painter Masaccio, the contemporary of Donatello, Masaccio, was the painterly descendant of Giotto, furthering the trend towards solidity of form and naturalism of face and gesture that he had begun a century earlier. Masaccios developments were carried forward in the paintings of Fra Angelico, the treatment of the elements of perspective and light in painting was of particular concern to 15th-century Florentine painters. Uccello was so obsessed with trying to achieve an appearance of perspective that, according to Vasari and his solutions can be seen in his masterpiece, the Battle of San Romano. In Naples, the painter Antonello da Messina began using oil paints for portraits and religious paintings at a date that preceded other Italian painters and he carried this technique north and influenced the painters of Venice

Baroque
–
The style began around 1600 in Rome and Italy, and spread to most of Europe. The aristocracy viewed the dramatic style of Baroque art and architecture as a means of impressing visitors by projecting triumph, power, Baroque palaces are built around an entrance of courts, grand staircases, and reception rooms of sequentially increasing opulence. However, baroque has a resonance and application that extend beyond a reduction to either a style or period. It is also yields the Italian barocco and modern Spanish barroco, German Barock, Dutch Barok, others derive it from the mnemonic term Baroco, a supposedly laboured form of syllogism in logical Scholastica. The Latin root can be found in bis-roca, in informal usage, the word baroque can simply mean that something is elaborate, with many details, without reference to the Baroque styles of the 17th and 18th centuries. The word Baroque, like most periodic or stylistic designations, was invented by later critics rather than practitioners of the arts in the 17th, the term Baroque was initially used in a derogatory sense, to underline the excesses of its emphasis. In particular, the term was used to describe its eccentric redundancy and noisy abundance of details, although it was long thought that the word as a critical term was first applied to architecture, in fact it appears earlier in reference to music. Another hypothesis says that the word comes from precursors of the style, Giacomo Barozzi da Vignola and he did not make the distinctions between Mannerism and Baroque that modern writers do, and he ignored the later phase, the academic Baroque that lasted into the 18th century. Long despised, Baroque art and architecture became fashionable between the two World Wars, and has remained in critical favour. In painting the gradual rise in popular esteem of Caravaggio has been the best barometer of modern taste, William Watson describes a late phase of Shang-dynasty Chinese ritual bronzes of the 11th century BC as baroque. The term Baroque may still be used, usually pejoratively, describing works of art, craft, the appeal of Baroque style turned consciously from the witty, intellectual qualities of 16th-century Mannerist art to a visceral appeal aimed at the senses. It employed an iconography that was direct, simple, obvious, germinal ideas of the Baroque can also be found in the work of Michelangelo. Even more generalised parallels perceived by some experts in philosophy, prose style, see the Neapolitan palace of Caserta, a Baroque palace whose construction began in 1752. In paintings Baroque gestures are broader than Mannerist gestures, less ambiguous, less arcane and mysterious, more like the stage gestures of opera, Baroque poses depend on contrapposto, the tension within the figures that move the planes of shoulders and hips in counterdirections. Baroque is a style of unity imposed upon rich, heavy detail, Baroque style featured exaggerated lighting, intense emotions, release from restraint, and even a kind of artistic sensationalism. There were highly diverse strands of Italian baroque painting, from Caravaggio to Cortona, the most prominent Spanish painter of the Baroque was Diego Velázquez. The later Baroque style gradually gave way to a more decorative Rococo, while the Baroque nature of Rembrandts art is clear, the label is less often used for Vermeer and many other Dutch artists. Flemish Baroque painting shared a part in this trend, while continuing to produce the traditional categories

Rococo
–
Rococo artists and architects used a more jocular, florid, and graceful approach to the Baroque. Their style was ornate and used light colours, asymmetrical designs, curves, unlike the political Baroque, the Rococo had playful and witty themes. By the end of the 18th century, Rococo was largely replaced by the Neoclassic style. In 1835 the Dictionary of the French Academy stated that the word Rococo usually covers the kind of ornament, style and design associated with Louis XVs reign and it includes therefore, all types of art from around the middle of the 18th century in France. The word is seen as a combination of the French rocaille and coquilles, the term may also be a combination of the Italian word barocco and the French rocaille and may describe the refined and fanciful style that became fashionable in parts of Europe in the 18th century. The Rococo love of shell-like curves and focus on decorative arts led some critics to say that the style was frivolous or merely modish, when the term was first used in English in about 1836, it was a colloquialism meaning old-fashioned. While there is some debate about the historical significance of the style to art in general. Italian architects of the late Baroque/early Rococo were wooed to Catholic Germany, Bohemia and Austria by local princes, an exotic but in some ways more formal type of Rococo appeared in France where Louis XIVs succession brought a change in the court artists and general artistic fashion. By the end of the long reign, rich Baroque designs were giving way to lighter elements with more curves. These elements are obvious in the designs of Nicolas Pineau. During the Régence, court life moved away from Versailles and this change became well established, first in the royal palace. The delicacy and playfulness of Rococo designs is seen as perfectly in tune with the excesses of Louis XVs reign. The 1730s represented the height of Rococo development in France, the style had spread beyond architecture and furniture to painting and sculpture, exemplified by the works of Antoine Watteau and François Boucher. The Rococo style was spread by French artists and engraved publications, william Hogarth helped develop a theoretical foundation for Rococo beauty. Though not intentionally referencing the movement, he argued in his Analysis of Beauty that the lines and S-curves prominent in Rococo were the basis for grace. The development of Rococo in Great Britain is considered to have connected with the revival of interest in Gothic architecture early in the 18th century. The beginning of the end for Rococo came in the early 1760s as figures like Voltaire and Jacques-François Blondel began to voice their criticism of the superficiality, Blondel decried the ridiculous jumble of shells, dragons, reeds, palm-trees and plants in contemporary interiors. By 1785, Rococo had passed out of fashion in France, replaced by the order, in Germany, late 18th century Rococo was ridiculed as Zopf und Perücke, and this phase is sometimes referred to as Zopfstil

Perspective (graphical)
–
Perspective in the graphic arts is an approximate representation, on a flat surface, of an image as it is seen by the eye. If viewed from the spot as the windowpane was painted. Each painted object in the scene is thus a flat, scaled down version of the object on the side of the window. All perspective drawings assume the viewer is a distance away from the drawing. Objects are scaled relative to that viewer, an object is often not scaled evenly, a circle often appears as an ellipse and a square can appear as a trapezoid. This distortion is referred to as foreshortening, Perspective drawings have a horizon line, which is often implied. This line, directly opposite the viewers eye, represents objects infinitely far away and they have shrunk, in the distance, to the infinitesimal thickness of a line. It is analogous to the Earths horizon, any perspective representation of a scene that includes parallel lines has one or more vanishing points in a perspective drawing. A one-point perspective drawing means that the drawing has a vanishing point, usually directly opposite the viewers eye. All lines parallel with the line of sight recede to the horizon towards this vanishing point. This is the standard receding railroad tracks phenomenon, a two-point drawing would have lines parallel to two different angles. Any number of vanishing points are possible in a drawing, one for each set of lines that are at an angle relative to the plane of the drawing. Perspectives consisting of parallel lines are observed most often when drawing architecture. In contrast, natural scenes often do not have any sets of parallel lines, the only method to indicate the relative position of elements in the composition was by overlapping, of which much use is made in works like the Parthenon Marbles. Chinese artists made use of perspective from the first or second century until the 18th century. It is not certain how they came to use the technique, some authorities suggest that the Chinese acquired the technique from India, oblique projection is also seen in Japanese art, such as in the Ukiyo-e paintings of Torii Kiyonaga. This was detailed within Aristotles Poetics as skenographia, using flat panels on a stage to give the illusion of depth, the philosophers Anaxagoras and Democritus worked out geometric theories of perspective for use with skenographia. Alcibiades had paintings in his house designed using skenographia, so this art was not confined merely to the stage, Euclids Optics introduced a mathematical theory of perspective, but there is some debate over the extent to which Euclids perspective coincides with the modern mathematical definition

Three-dimensional space
–
Three-dimensional space is a geometric setting in which three values are required to determine the position of an element. This is the meaning of the term dimension. In physics and mathematics, a sequence of n numbers can be understood as a location in n-dimensional space, when n =3, the set of all such locations is called three-dimensional Euclidean space. It is commonly represented by the symbol ℝ3 and this serves as a three-parameter model of the physical universe in which all known matter exists. However, this space is one example of a large variety of spaces in three dimensions called 3-manifolds. Furthermore, in case, these three values can be labeled by any combination of three chosen from the terms width, height, depth, and breadth. In mathematics, analytic geometry describes every point in space by means of three coordinates. Three coordinate axes are given, each perpendicular to the two at the origin, the point at which they cross. They are usually labeled x, y, and z, below are images of the above-mentioned systems. Two distinct points determine a line. Three distinct points are either collinear or determine a unique plane, four distinct points can either be collinear, coplanar or determine the entire space. Two distinct lines can intersect, be parallel or be skew. Two parallel lines, or two intersecting lines, lie in a plane, so skew lines are lines that do not meet. Two distinct planes can either meet in a line or are parallel. Three distinct planes, no pair of which are parallel, can meet in a common line. In the last case, the three lines of intersection of each pair of planes are mutually parallel, a line can lie in a given plane, intersect that plane in a unique point or be parallel to the plane. In the last case, there will be lines in the plane that are parallel to the given line, a hyperplane is a subspace of one dimension less than the dimension of the full space. The hyperplanes of a space are the two-dimensional subspaces, that is

Two-dimensional space
–
In physics and mathematics, two-dimensional space is a geometric model of the planar projection of the physical universe. The two dimensions are commonly called length and width, both directions lie in the same plane. A sequence of n numbers can be understood as a location in n-dimensional space. When n =2, the set of all locations is called two-dimensional space or bi-dimensional space. Each reference line is called an axis or just axis of the system. The coordinates can also be defined as the positions of the projections of the point onto the two axes, expressed as signed distances from the origin. The idea of system was developed in 1637 in writings by Descartes and independently by Pierre de Fermat. Both authors used a single axis in their treatments and have a length measured in reference to this axis. The concept of using a pair of axes was introduced later, after Descartes La Géométrie was translated into Latin in 1649 by Frans van Schooten and these commentators introduced several concepts while trying to clarify the ideas contained in Descartes work. Later, the plane was thought of as a field, where any two points could be multiplied and, except for 0, divided and this was known as the complex plane. The complex plane is called the Argand plane because it is used in Argand diagrams. These are named after Jean-Robert Argand, although they were first described by Norwegian-Danish land surveyor, Argand diagrams are frequently used to plot the positions of the poles and zeroes of a function in the complex plane. In mathematics, analytic geometry describes every point in space by means of two coordinates. Two perpendicular coordinate axes are given which cross each other at the origin and they are usually labeled x and y. Another widely used system is the polar coordinate system, which specifies a point in terms of its distance from the origin. In two dimensions, there are infinitely many polytopes, the polygons, the first few regular ones are shown below, The Schläfli symbol represents a regular p-gon. The regular henagon and regular digon can be considered degenerate regular polygons and they can exist nondegenerately in non-Euclidean spaces like on a 2-sphere or a 2-torus. There exist infinitely many non-convex regular polytopes in two dimensions, whose Schläfli symbols consist of rational numbers and they are called star polygons and share the same vertex arrangements of the convex regular polygons

Oculus
–
An oculus is a circular opening in the centre of a dome or in a wall. Originating in antiquity, it is a feature of Byzantine and Neoclassical architecture and it is also known as an œil de boeuf from the French, or simply a bulls-eye. The oculus was used by the Romans, one of the finest examples being that in the dome of the Pantheon, open to the weather, it allows rain to enter and fall to the floor, where it is carried away through drains. Though the opening looks small, it actually has a diameter of 27 ft allowing it to light the building just as the sun lights the earth, the rain also keeps the building cool during the hot summer months. Pliny in his Natural history call counters also oculus, oculi, the oculus was widely used in the architecture of the Byzantine Empire. It was applied to buildings in Syria in the 5th and 6th centuries, in Constantinoples Myrelaion Church, there are two oculi above the stringcourse on both lateral facades. Early examples of the oculus in Renaissance architecture can be seen in Florence Cathedral, in the nave clerestorey, since the revival of dome construction beginning in the Italian Renaissance, open oculi have been replaced by light-transmitting cupolas and other round windows, openings, and skylights. They can be seen in the pediments of Palladios Villa Rotonda, use of oculus windows became more popular in Baroque architecture. Widely used by Neo-Palladian architects including Colen Campbell, one can be seen in the dome of Thomas Jeffersons Rotunda at the University of Virginia

Andrea Mantegna
–
Andrea Mantegna was an Italian painter, a student of Roman archeology, and son-in-law of Jacopo Bellini. Like other artists of the time, Mantegna experimented with perspective and his flinty, metallic landscapes and somewhat stony figures give evidence of a fundamentally sculptural approach to painting. He also led a workshop that was the producer of prints in Venice before 1500. Mantegna was born in Isola di Carturo, Republic of Venice close to Padua, second son of a carpenter, at the age of eleven he became the apprentice of Francesco Squarcione, Paduan painter. Squarcione, whose vocation was tailoring, appears to have had a remarkable enthusiasm for ancient art. All the while, he continued undertaking works on commission for which his pupils no less than himself were made available, as many as 137 painters and pictorial students passed through Squarciones school, which had been established towards 1440 and which became famous all over Italy. Padua was attractive for artists coming not only from Veneto but also from Tuscany, such as Paolo Uccello, Filippo Lippi, Mantegnas early career was shaped indeed by impressions of Florentine works. At the time, Mantegna was said to be a favorite pupil, Squarcione taught him Latin and instructed him to study fragments of Roman sculpture. The master also preferred forced perspective, the results of which may account for some of Mantegnas later innovations. However, at the age of seventeen, Mantegna separated himself from Squarcione and he later claimed that Squarcione had profited from his work without paying the rights. His first work, now lost, was an altarpiece for the church of Santa Sofia in 1448. After a series of coincidences, Mantegna finished most of the work alone, though Ansuino and this series was almost entirely lost in the 1944 allied bombings of Padua. The most dramatic work of the cycle was the work set in the worms-eye view perspective. The sketch of the St. Stephen fresco survived and is the earliest known preliminary sketch which still exists to compare to the corresponding fresco, the drawing shows proof that nude figures were used in the conception of works during the Early Renaissance. In the preliminary sketch, the perspective is less developed and closer to a more average viewpoint however, despite the authentic look of the monument, it is not a copy of any known Roman structure. Luke and other saints for the church of S. Giustina, as the young artist progressed in his work, he came under the influence of Jacopo Bellini, father of the celebrated painters Giovanni Bellini and Gentile Bellini, and of a daughter Nicolosia. In 1453 Jacopo consented to a marriage between Nicolosia and Mantegna, trained as he had been in the study of marbles and the severity of the antique, Mantegna openly avowed that he considered ancient art superior to nature as being more eclectic in form. As a result, the painter exercised precision in outline, privileging the figure, overall, Mantegnas work thus tended towards rigidity, demonstrating an austere wholeness rather than graceful sensitivity of expression
