Venice
–
Venice is a city in northeastern Italy and the capital of the Veneto region. It is situated across a group of 118 small islands that are separated by canals and these are located in the shallow Venetian Lagoon, an enclosed bay that lies between the mouths of the Po and the Piave Rivers. Parts of Venice are renowned for the beauty of their settings, their architecture, the lagoon and a part of the city are listed as a World Heritage Site. In 2014,264,579 people resided in Comune di Venezia, together with Padua and Treviso, the city is included in the Padua-Treviso-Venice Metropolitan Area, with a total population of 2.6 million. PATREVE is a metropolitan area without any degree of autonomy. The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC, the city was historically the capital of the Republic of Venice. Venice has been known as the La Dominante, Serenissima, Queen of the Adriatic, City of Water, City of Masks, City of Bridges, The Floating City, and City of Canals. The City State of Venice is considered to have been the first real international financial center which gradually emerged from the 9th century to its peak in the 14th century and this made Venice a wealthy city throughout most of its history. It is also known for its several important artistic movements, especially the Renaissance period, Venice has played an important role in the history of symphonic and operatic music, and it is the birthplace of Antonio Vivaldi. Venice has been ranked the most beautiful city in the world as of 2016, the name Venetia, however, derives from the Roman name for the people known as the Veneti, and called by the Greeks Eneti. The meaning of the word is uncertain, although there are other Indo-European tribes with similar-sounding names, such as the Celtic Veneti, Baltic Veneti, and the Slavic Wends. Linguists suggest that the name is based on an Indo-European root *wen, so that *wenetoi would mean beloved, lovable, a connection with the Latin word venetus, meaning the color sea-blue, is also possible. The alternative obsolete form is Vinegia, some late Roman sources reveal the existence of fishermen on the islands in the original marshy lagoons. They were referred to as incolae lacunae, the traditional founding is identified with the dedication of the first church, that of San Giacomo on the islet of Rialto — said to have taken place at the stroke of noon on 25 March 421. Beginning as early as AD166 to 168, the Quadi and Marcomanni destroyed the center in the area. The Roman defences were again overthrown in the early 5th century by the Visigoths and, some 50 years later, New ports were built, including those at Malamocco and Torcello in the Venetian lagoon. The tribuni maiores, the earliest central standing governing committee of the islands in the Lagoon, the traditional first doge of Venice, Paolo Lucio Anafesto, was actually Exarch Paul, and his successor, Marcello Tegalliano, was Pauls magister militum. In 726 the soldiers and citizens of the Exarchate rose in a rebellion over the controversy at the urging of Pope Gregory II

Republic of Venice
–
It was based in the lagoon communities of the historically prosperous city of Venice. It was a leading European economic and trading power during the Middle Ages, the Venetian city state was founded as a safe haven for people escaping persecution in mainland Europe after the fall of the Roman Empire. In its early years, it prospered on the salt trade, in subsequent centuries, the city state established a thalassocracy. It dominated trade on the Mediterranean Sea, including commerce between Asia, Europe and North Africa, the Venetian navy was used in the Crusades. Venice achieved territorial conquests along the Adriatic Sea, the city became home to an extremely wealthy merchant class, who patronized renowned art and architecture along the citys lagoons. Venetian merchants were influential financiers in Europe, the city was also the birthplace of great European explorers, including Marco Polo, as well as the classical music composer Vivaldi. The republic was ruled by the Doge, who was elected by members of the Great Council of Venice, the ruling class was an oligarchy of merchants and aristocrats. Venice and other Italian maritime republics played a key role in fostering capitalism, Venetian citizens generally supported the system of governance. The city-state enforced strict laws and employed ruthless tactics in its prisons, the opening of new trade routes to the Americas and the East Indies via the Atlantic Ocean marked the beginning of Venices decline as a maritime republic. The city state suffered defeats from the navy of the Ottoman Empire, in 1797, the country was colonized by Austria and France, following an invasion by Napoleon Bonaparte. Venice became a part of a unified Italy in the 19th century and it was formally known as the Most Serene Republic of Venice and is often referred to as La Serenissima, in reference to its title as one of the Most Serene Republics. He was the first historical Doge of Venice, whichever the case, the first doges had their power base in Heraclea. Ursuss successor, Deusdedit, moved his seat from Heraclea to Malamocco in the 740s and he was the son of Ursus and represented the attempt of his father to establish a dynasty. Such attempts were more commonplace among the doges of the first few centuries of Venetian history. They desired to remain well-connected to the Empire, another faction, republican in nature, believed in continuing along a course towards practical independence. The other main faction was pro-Frankish, supported mostly by clergy, they looked towards the new Carolingian king of the Franks, Pepin the Short, as the best provider of defence against the Lombards. A minor, pro-Lombard faction was opposed to close ties with any of these further-off powers, the successors of Obelerio inherited a united Venice. By the Pax Nicephori, the two emperors had recognised that Venice belonged to the Byzantine sphere of influence, many centuries later, the Venetians claimed that the treaty had recognised Venetian de facto independence, but the truth of this claim is doubted by modern scholars

Warsaw
–
Warsaw is the capital and largest city of Poland. It stands on the Vistula River in east-central Poland, roughly 260 kilometres from the Baltic Sea and 300 kilometres from the Carpathian Mountains. Its population is estimated at 1.750 million residents within a metropolitan area of 3.101 million residents. The city limits cover 516.9 square kilometres, while the area covers 6,100.43 square kilometres. Once described as Paris of the East, Warsaw was believed to be one of the most beautiful cities in the world until World War II. On 9 November 1939, the city was awarded Polands highest military decoration for heroism, Warsaw is one of Europe’s most dynamic metropolitan cities. In 2012 the Economist Intelligence Unit ranked Warsaw as the 32nd most liveable city in the world, in 2017 the city came 4th in the “Business-friendly” category and 8th in the “Human capital and life style”. It was also ranked as one of the most liveable cities in Central, Warsaw is considered an Alpha– global city, a major international tourist destination and a significant cultural, political and economic hub. The city is a significant centre of research and development, BPO, ITO, the Warsaw Stock Exchange is the largest and most important in Central and Eastern Europe. Frontex, the European Union agency for external security, has its headquarters in Warsaw. Together with Frankfurt, London and Paris, Warsaw is also one of the cities with the highest number of skyscrapers in the European Union, the city is the seat of the Polish Academy of Sciences, Warsaw National Philharmonic Orchestra and the University of Warsaw. The historic city-centre of Warsaw with its picturesque Old Town in 1980 was listed as a UNESCO World Heritage Site, buildings represent examples of nearly every European architectural style and historical period. Warsaw provides many examples of architecture from the gothic, renaissance, baroque, neoclassical and modern periods, furthermore, the city is positioning itself as Europes chic cultural capital with thriving art and club scenes and renowned restaurants. Folk etymology attributes the city name to a fisherman, Wars, according to legend, Sawa was a mermaid living in the Vistula River with whom Wars fell in love. In actuality, Warsz was a 12th/13th-century nobleman who owned a village located at the site of Mariensztat neighbourhood. See also the Vršovci family which had escaped to Poland, the official city name in full is miasto stołeczne Warszawa. A native or resident of Warsaw is known as a Varsovian – in Polish warszawiak, warszawianin, warszawianka, warszawiacy, other names for Warsaw include Varsovia and Varsóvia, Varsovie, Varsavia, Warschau, װאַרשע /Varshe, Варшава /Varšava /Varshava, Varšuva, Varsó. The first fortified settlements on the site of todays Warsaw were located in Bródno, after Jazdów was raided by nearby clans and dukes, a new similar settlement was established on the site of a small fishing village called Warszowa

Poland
–
Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges in the south. Bordered by Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, the total area of Poland is 312,679 square kilometres, making it the 69th largest country in the world and the 9th largest in Europe. With a population of over 38.5 million people, Poland is the 34th most populous country in the world, the 8th most populous country in Europe, Poland is a unitary state divided into 16 administrative subdivisions, and its capital and largest city is Warsaw. Other metropolises include Kraków, Wrocław, Poznań, Gdańsk and Szczecin, the establishment of a Polish state can be traced back to 966, when Mieszko I, ruler of a territory roughly coextensive with that of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, and in 1569 it cemented a political association with the Grand Duchy of Lithuania by signing the Union of Lublin. This union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, Poland regained its independence in 1918 at the end of World War I, reconstituting much of its historical territory as the Second Polish Republic. In September 1939, World War II started with the invasion of Poland by Nazi Germany, followed thereafter by invasion by the Soviet Union. More than six million Polish citizens died in the war, after the war, Polands borders were shifted westwards under the terms of the Potsdam Conference. With the backing of the Soviet Union, a communist puppet government was formed, and after a referendum in 1946. During the Revolutions of 1989 Polands Communist government was overthrown and Poland adopted a new constitution establishing itself as a democracy, informally called the Third Polish Republic. Since the early 1990s, when the transition to a primarily market-based economy began, Poland has achieved a high ranking on the Human Development Index. Poland is a country, which was categorised by the World Bank as having a high-income economy. Furthermore, it is visited by approximately 16 million tourists every year, Poland is the eighth largest economy in the European Union and was the 6th fastest growing economy on the continent between 2010 and 2015. According to the Global Peace Index for 2014, Poland is ranked 19th in the list of the safest countries in the world to live in. The origin of the name Poland derives from a West Slavic tribe of Polans that inhabited the Warta River basin of the historic Greater Poland region in the 8th century, the origin of the name Polanie itself derives from the western Slavic word pole. In some foreign languages such as Hungarian, Lithuanian, Persian and Turkish the exonym for Poland is Lechites, historians have postulated that throughout Late Antiquity, many distinct ethnic groups populated the regions of what is now Poland. The most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, the Slavic groups who would form Poland migrated to these areas in the second half of the 5th century AD. With the Baptism of Poland the Polish rulers accepted Christianity and the authority of the Roman Church

Landscape painting
–
In other works, landscape backgrounds for figures can still form an important part of the work. Sky is almost always included in the view, and weather is often an element of the composition, detailed landscapes as a distinct subject are not found in all artistic traditions, and develop when there is already a sophisticated tradition of representing other subjects. The two main traditions spring from Western painting and Chinese art, going well over a thousand years in both cases. Landscape views in art may be imaginary, or copied from reality with varying degrees of accuracy. If the primary purpose of a picture is to depict an actual, specific place, especially including buildings prominently, within a few decades it was used to describe vistas in poetry, and eventually as a term for real views. However the cognate term landscaef or landskipe for a patch of land had existed in Old English. The earliest pure landscapes with no figures are frescos from Minoan Greece of around 1500 BCE. The frescos from the Tomb of Nebamun, now in the British Museum, are a famous example. These were frequently used, as in the illustrated, to bridge the gap between a foreground scene with figures and a distant panoramic vista, a persistent problem for landscape artists. The Chinese style generally showed only a distant view, or used dead ground or mist to avoid that difficulty, aesthetic theories in both regions gave the highest status to the works seen to require the most imagination from the artist. They were often also poets whose lines and images illustrated each other, a revival in interest in nature initially mainly manifested itself in depictions of small gardens such as the Hortus Conclusus or those in millefleur tapestries. The frescos of figures at work or play in front of a background of trees in the Palace of the Popes. Several frescos of gardens have survived from Roman houses like the Villa of Livia, a particular advance is shown in the less well-known Turin-Milan Hours, now largely destroyed by fire, whose developments were reflected in Early Netherlandish painting for the rest of the century. Landscape backgrounds for various types of painting became prominent and skilful during the 15th century. The Italian development of a system of graphical perspective was now known all over Europe. Indeed, certain styles were so popular that they became formulas that could be copied again and again, after the publication of the Small Landscapes, landscape artists in the Low Countries either continued with the world landscape or followed the new mode presented by the Small Landscapes. The popularity of landscape scenes can be seen in the success of the painter Frans Post. Salvator Rosa gave picturesque excitement to his landscapes by showing wilder Southern Italian country, there are different styles and periods, and subgenres of marine and animal painting, as well as a distinct style of Italianate landscape

Italians
–
Italians are a nation and ethnic group native to Italy who share a common culture, ancestry and speak the Italian language as a native tongue. The majority of Italian nationals are speakers of Standard Italian. Italians have greatly influenced and contributed to the arts and music, science, technology, cuisine, sports, fashion, jurisprudence, banking, Italian people are generally known for their localism and their attention to clothing and family values. The term Italian is at least 3,000 years old and has a history that goes back to pre-Roman Italy. According to one of the common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The Etruscan civilization reached its peak about the 7th century BC, but by 509 BC, when the Romans overthrew their Etruscan monarchs, its control in Italy was on the wane. By 350 BC, after a series of wars between Greeks and Etruscans, the Latins, with Rome as their capital, gained the ascendancy by 272 BC, and they managed to unite the entire Italian peninsula. This period of unification was followed by one of conquest in the Mediterranean, in the course of the century-long struggle against Carthage, the Romans conquered Sicily, Sardinia and Corsica. Finally, in 146 BC, at the conclusion of the Third Punic War, with Carthage completely destroyed and its inhabitants enslaved, octavian, the final victor, was accorded the title of Augustus by the Senate and thereby became the first Roman emperor. After two centuries of rule, in the 3rd century AD, Rome was threatened by internal discord and menaced by Germanic and Asian invaders. Emperor Diocletians administrative division of the empire into two parts in 285 provided only temporary relief, it became permanent in 395, in 313, Emperor Constantine accepted Christianity, and churches thereafter rose throughout the empire. However, he moved his capital from Rome to Constantinople. The last Western emperor, Romulus Augustulus, was deposed in 476 by a Germanic foederati general in Italy and his defeat marked the end of the western part of the Roman Empire. During most of the period from the fall of Rome until the Kingdom of Italy was established in 1861, Odoacer ruled well for 13 years after gaining control of Italy in 476. Then he was attacked and defeated by Theodoric, the king of another Germanic tribe, Theodoric and Odoacer ruled jointly until 493, when Theodoric murdered Odoacer. Theodoric continued to rule Italy with an army of Ostrogoths and a government that was mostly Italian, after the death of Theodoric in 526, the kingdom began to grow weak

Painting
–
Painting is the practice of applying paint, pigment, color or other medium to a solid surface. The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, Painting is a mode of creative expression, and the forms are numerous. Drawing, gesture, composition, narration, or abstraction, among other aesthetic modes, may serve to manifest the expressive, Paintings can be naturalistic and representational, photographic, abstract, narrative, symbolistic, emotive, or political in nature. A portion of the history of painting in both Eastern and Western art is dominated by motifs and ideas. In art, the term painting describes both the act and the result of the action, the term painting is also used outside of art as a common trade among craftsmen and builders. What enables painting is the perception and representation of intensity, every point in space has different intensity, which can be represented in painting by black and white and all the gray shades between. In practice, painters can articulate shapes by juxtaposing surfaces of different intensity, thus, the basic means of painting are distinct from ideological means, such as geometrical figures, various points of view and organization, and symbols. In technical drawing, thickness of line is ideal, demarcating ideal outlines of an object within a perceptual frame different from the one used by painters. Color and tone are the essence of painting as pitch and rhythm are the essence of music, color is highly subjective, but has observable psychological effects, although these can differ from one culture to the next. Black is associated with mourning in the West, but in the East, some painters, theoreticians, writers and scientists, including Goethe, Kandinsky, and Newton, have written their own color theory. Moreover, the use of language is only an abstraction for a color equivalent, the word red, for example, can cover a wide range of variations from the pure red of the visible spectrum of light. There is not a register of different colors in the way that there is agreement on different notes in music. For a painter, color is not simply divided into basic, painters deal practically with pigments, so blue for a painter can be any of the blues, phthalocyanine blue, Prussian blue, indigo, cobalt, ultramarine, and so on. Psychological and symbolical meanings of color are not, strictly speaking, colors only add to the potential, derived context of meanings, and because of this, the perception of a painting is highly subjective. The analogy with music is quite clear—sound in music is analogous to light in painting, shades to dynamics and these elements do not necessarily form a melody of themselves, rather, they can add different contexts to it. Modern artists have extended the practice of painting considerably to include, as one example, collage, some modern painters incorporate different materials such as sand, cement, straw or wood for their texture. Examples of this are the works of Jean Dubuffet and Anselm Kiefer, there is a growing community of artists who use computers to paint color onto a digital canvas using programs such as Adobe Photoshop, Corel Painter, and many others. These images can be printed onto traditional canvas if required, rhythm is important in painting as it is in music

Printmaking
–
Printmaking is the process of making artworks by printing, normally on paper. Printmaking normally covers only the process of creating prints that have an element of originality, except in the case of monotyping, the process is capable of producing multiples of the same piece, which is called a print. Each print produced is not considered a copy but rather is considered an original, a print may be known as an impression. Printmaking is not chosen only for its ability to multiple impressions. Prints are created by transferring ink from a matrix or through a screen to a sheet of paper or other material. Screens made of silk or synthetic fabrics are used for the screenprinting process, other types of matrix substrates and related processes are discussed below. Multiple impressions printed from the matrix form an edition. Prints may also be printed in book form, such as illustrated books or artists books, Printmaking techniques are generally divided into the following basic categories, Relief, where ink is applied to the original surface of the matrix. Relief techniques include woodcut or woodblock as the Asian forms are known, wood engraving. Intaglio, where ink is applied beneath the surface of the matrix. Intaglio techniques include engraving, etching, mezzotint, aquatint, planographic, where the matrix retains its original surface, but is specially prepared and/or inked to allow for the transfer of the image. Planographic techniques include lithography, monotyping, and digital techniques, stencil, where ink or paint is pressed through a prepared screen, including screenprinting and pochoir. Other types of printmaking techniques outside these groups include collagraphy and viscosity printing, collagraphy is a printmaking technique in which textured material is adhered to the printing matrix. This texture is transferred to the paper during the printing process, Contemporary printmaking may include digital printing, photographic mediums, or a combination of digital, photographic, and traditional processes. Many of these techniques can also be combined, especially within the same family, for example, Rembrandts prints are usually referred to as etchings for convenience, but very often include work in engraving and drypoint as well, and sometimes have no etching at all. Woodcut, a type of print, is the earliest printmaking technique. It was probably first developed as a means of printing patterns on cloth, woodcuts of images on paper developed around 1400 in Japan, and slightly later in Europe. These are the two areas where woodcut has been most extensively used purely as a process for making images without text, the artist draws a design on a plank of wood, or on paper which is transferred to the wood

Etching
–
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal. In modern manufacturing, other chemicals may be used on other types of material, as a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of variants such as microfabrication etching and photochemical milling it is a crucial technique in much modern technology. In traditional pure etching, a plate is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with an etching needle where he or she wants a line to appear in the finished piece. The échoppe, a tool with an oval section, is also used for swelling lines. The plate is dipped in a bath of acid, technically called the mordant or etchant. The acid bites into the metal where it is exposed, leaving behind lines sunk into the plate, the remaining ground is then cleaned off the plate. The plate is inked all over, and then the ink wiped off the surface, the plate is then put through a high-pressure printing press together with a sheet of paper. The paper picks up the ink from the lines, making a print. The process can be repeated many times, typically several hundred impressions could be printed before the shows much sign of wear. The work on the plate can also be added to by repeating the whole process, Etching has often been combined with other intaglio techniques such as engraving or aquatint. The process as applied to printmaking is believed to have been invented by Daniel Hopfer of Augsburg, Hopfer was a craftsman who decorated armour in this way, and applied the method to printmaking, using iron plates. Apart from his prints, there are two examples of his work on armour, a shield from 1536 now in the Real Armeria of Madrid. The switch to copper plates was made in Italy. On the other hand, the handling of the ground and acid need skill and experience, prior to 1100 AD, the New World Hohokam independently utilized the technique of acid etching in marine shell designs. Jacques Callot from Nancy in Lorraine made important technical advances in etching technique and he developed the échoppe, a type of etching-needle with a slanting oval section at the end, which enabled etchers to create a swelling line, as engravers were able to do. Callot also appears to have responsible for an improved, harder, recipe for the etching ground

Canaletto
–
Giovanni Antonio Canal, better known as Canaletto, was an Italian painter of city views or vedute, of Venice. He also painted views, although the demarcation in his works between the real and the imaginary is never quite clearcut. He was further an important printmaker using the etching technique, in the period from 1746 to 1756 he worked in England where he created many sights of London. He was highly successful in England, thanks to the British merchant and connoisseur Joseph Smith and he was born in Venice as the son of the painter Bernardo Canal, hence his mononym Canaletto, and Artemisia Barbieri. Canaletto served his apprenticeship with his father and his brother and he began in his fathers occupation, that of a theatrical scene painter. Canaletto was inspired by the Roman vedutista Giovanni Paolo Pannini, and started painting the life of the city. After returning from Rome in 1719, he began painting in his topographical style and his first known signed and dated work is Architectural Capriccio. Studying with the older Luca Carlevarijs, a painter of urban cityscapes. It is like Carlevaris, but you can see the sun shining in it, much of Canalettos early artwork was painted from nature, differing from the then customary practice of completing paintings in the studio. However, his paintings are notable for their accuracy, he recorded the seasonal submerging of Venice in water. Canalettos early works remain his most coveted and, according to many authorities, one of his early pieces is The Stonemasons Yard which depicts a humble working area of the city. It is regarded one of his finest works and was presented by Sir George Beaumont in 1823/8, later Canaletto painted grand scenes of the canals of Venice and the Doges Palace. His large-scale landscapes portrayed the citys pageantry and waning traditions, making use of atmospheric effects. For these qualities, his works may be said to have anticipated Impressionism and his graphic print S. A Giustina in Prà della Vale was found in the 2012 Nazi loot discovery. Many of his pictures were sold to Englishmen on their Grand Tour and it was Smith who acted as an agent for Canaletto, first in requesting paintings of Venice from the painter in the early 1720s and helping him to sell his paintings to other Englishmen. In the 1740s Canalettos market was disrupted when the War of the Austrian Succession led to a reduction in the number of British visitors to Venice and he remained in England until 1755, producing views of London and of his patrons castles and houses. His 1754 painting of Old Walton Bridge includes an image of Canaletto himself and he was often expected to paint England in the fashion with which he had painted his native city. Historian Michael Levey described his work from this period as inhibited, the artist was compelled to give public painting demonstrations in order to refute this claim, however, his reputation never fully recovered in his lifetime

Camera obscura
–
The surroundings of the projected image have to be relatively dark for the image to be clear, so many historical camera obscura experiments were performed in dark rooms. The term camera obscura also refers to constructions or devices that use of the principle within a box. Camerae obscurae with a lens in the opening have been used since the second half of the 16th century, before the term camera obscura was first used in 1604, many other expressions were used including cubiculum obscurum, cubiculum tenebricosum, conclave obscurum and locus obscurus. Rays of light travel in straight lines and change when they are reflected and partly absorbed by an object, retaining information about the color, lit objects reflect rays of light in all directions. The human eye itself works much like a camera obscura with an opening, a biconvex lens, a camera obscura device consists of a box, tent or room with a small hole in one side. Light from a scene passes through the hole and strikes a surface inside, where the scene is reproduced, inverted and reversed. The image can be projected onto paper, and can then be traced to produce an accurate representation. In order to produce a reasonably clear projected image, the aperture has to be about 1/100th the distance to the screen, many camerae obscurae use a lens rather than a pinhole because it allows a larger aperture, giving a usable brightness while maintaining focus. As the pinhole is made smaller, the image gets sharper, with too small a pinhole, however, the sharpness worsens, due to diffraction. Using mirrors, as in an 18th-century overhead version, it is possible to project a right-side-up image, another more portable type is a box with an angled mirror projecting onto tracing paper placed on the glass top, the image being upright as viewed from the back. There are theories that occurrences of camera obscura effects inspired paleolithic cave paintings and it is also suggested that camera obscura projections could have played a role in Neolithic structures. Perforated gnomons projecting an image of the sun were described in the Chinese Zhoubi Suanjing writings. The location of the circle can be measured to tell the time of day. In Arab and European cultures its invention was later attributed to Egyptian astronomer. Some ancient sightings of gods and spirits, especially in worship, are thought to possibly have been conjured up by means of camera obscura projections. In these writings it is explained how the image in a collecting-point or treasure house is inverted by an intersecting point that collected the light. Light coming from the foot of a person would partly be hidden below. Rays from the head would partly be hidden above and partly form the part of the image
