Satire On False Perspective
''Satire on False Perspective'' is the title of an engraving produced by William Hogarth in 1754 for his friend Joshua Kirby's pamphlet on linear perspective. The intent of the work is clearly given by its caption: Summary The work shows a scene that provides many deliberate examples of confused and misplaced perspective effects. Although the individual components of the scene seem self-consistent, the scene itself can be classed as an example of an impossible object. Partial list of "errors" # The man in the foreground's fishing rod's line passes behind that of the man behind him. # The sign is moored to two buildings, one in front of the other, with beams that show no difference in depth # The sign is overlapped by two distant trees. # The man climbing the hill is lighting his pipe with the candle of the woman leaning out of the upper story window. # The crow perched on the tree is massive in comparison to it. # The church appears to front onto the river. Both ends of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Hogarth
William Hogarth (; 10 November 1697 – 26 October 1764) was an English painter, engraver, pictorial satirist, social critic, editorial cartoonist and occasional writer on art. His work ranges from realistic portraiture to comic strip-like series of pictures called "modern moral subjects", and he is perhaps best known for his series ''A Harlot's Progress'', ''A Rake's Progress'' and '' Marriage A-la-Mode''. Knowledge of his work is so pervasive that satirical political illustrations in this style are often referred to as "Hogarthian". Hogarth was born in London to a lower-middle-class family. In his youth he took up an apprenticeship with an engraver, but did not complete the apprenticeship. His father underwent periods of mixed fortune, and was at one time imprisoned in lieu of outstanding debts, an event that is thought to have informed William's paintings and prints with a hard edge. Influenced by French and Italian painting and engraving, Hogarth's works are mostly sat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning th ...

Joshua Kirby (artist)
Joshua Kirby (1716, Parham, Suffolk – 1774, Kew), often mistakenly called John Joshua Kirby, was an English 18th-century landscape painter, engraver, writer, draughtsman and architect famed for his publications and teaching on linear perspective based on Brook Taylor's mathematics. Biography Joshua was the second of five sons of topographer John Kirby. In early life he assisted his father in the preparation of his important Survey of Suffolk, which took the form of a volume (1735) entitled ''The Suffolk Traveller'', an extensive gazetteer in which the parishes and towns, and the principal landowners, seats, advowsons, antiquities and industries of the two counties of West and East Suffolk were described, the text counterpart of John Kirby's County Map published in 1736. In 1739 Joshua married Sarah Bull, and his children Sarah (afterwards Mrs. Sarah Trimmer) and William soon followed. From an early age he was very studious, but, showing special aptitude as an artist, he set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Perspective
Linear or point-projection perspective (from la, perspicere 'to see through') is one of two types of 3D projection, graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper. The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to ''foreshortening'', meaning that an object's dimensions along the line of sight appear shorter than its dimensions across the line of sight. All objects will recede to points in the distance, usually along the horizon line, but also above and below the horizon line depending on the view used.

Book Frontispiece
A frontispiece in books is a decorative or informative illustration facing a book's title page—on the left-hand, or verso, page opposite the right-hand, or recto, page. In some ancient editions or in modern luxury editions the frontispiece features thematic or allegory, allegorical elements, in others is the author's portrait that appears as the frontispiece. In medieval illuminated manuscripts, a presentation miniature showing the book or text being presented (by whom and to whom varies) was often used as a frontispiece. Origin The word comes from the French language, French ''frontispice'', which derives from the late Latin ''frontispicium'', composed of the Latin ''frons'' ('forehead') and ''specere'' ('to look at'). It was synonymous with 'metoposcopy'. In English, it was originally used as an frontispiece (architecture), architectural term, referring to the decorative facade of a building. In the 17th century, in other languages as in Italian language, Italian, the term cam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Impossible Object
An impossible object (also known as an impossible figure or an undecidable figure) is a type of optical illusion that consists of a two-dimensional figure which is instantly and naturally understood as representing a projection of a three-dimensional object. Impossible objects are of interest to psychologists, mathematicians and artists without falling entirely into any one discipline. Notable examples Notable impossible objects include: * Borromean rings — although conventionally drawn as three linked circles in three-dimensional space, any realization must be non-circular * Impossible cube — invented by M.C. Escher for ''Belvedere'', a lithograph in which a boy seated at the foot of the building holds an impossible cube. * Penrose stairs – created by Oscar Reutersvärd and later independently devised and popularised by Lionel Penrose and his mathematician son Roger Penrose. A variation on the Penrose triangle, it is a two-dimensional depiction of a staircase in which the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Rod
A fishing rod is a long, thin rod used by angling, anglers to fishing, catch fish by manipulating a fishing line, line ending in a fish hook, hook (formerly known as an ''angle'', hence the term "angling"). At its most basic form, a fishing rod is a straight rigid stick/pole with a line attached to one end (as seen in traditional Tenkara fishing); however, modern rods are usually elastic and generally have the line stored in a fishing reel, reel mounted at the rod handle, which is hand-cranked and controls the line retrieval, as well as numerous line-restricting rings (also known as ''line guides'') that distribute bending stress along the rod and help dampening down/prevent line whipping and entanglement. To better entice fish, fishing bait, baits or fishing lure, lures are dressed onto the one or more hooks attached to the line, and a bite indicator is used, some of which (e.g. quiver tip) might be incorporated as part of the rod itself. Fishing rod acts as an extended leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoking Pipe (tobacco)
A tobacco pipe, often called simply a pipe, is a device specifically made to smoke tobacco. It comprises a chamber (the bowl) for the tobacco from which a thin hollow stem (shank) emerges, ending in a mouthpiece. Pipes can range from very simple machine-made briar models to highly prized hand-made artisanal implements made by renowned pipemakers, which are often very expensive collector's items. Pipe smoking is the oldest known traditional form of tobacco smoking. History Some cultures of the indigenous peoples of the Americas smoke tobacco in ceremonial pipes, and have done so since long before the arrival of Europeans. For instance the Lakota people use a ceremonial pipe called čhaŋnúŋpa. Other cultures of the indigenous peoples of the Americas smoke tobacco socially. The tobacco plant is native to South America but spread into North America long before Europeans arrived. Tobacco was introduced to Europe from the Americas in the 16th century and spread around the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crow
A crow is a bird of the genus ''Corvus'', or more broadly a synonym for all of ''Corvus''. Crows are generally black in colour. The word "crow" is used as part of the common name of many species. The related term "raven" is not pinned scientifically to any certain trait, but is rather a general grouping for larger ''Corvus spp.'' Species * ''Corvus albus'' – pied crow (Central African coasts to southern Africa) * ''Corvus bennetti'' – little crow (Australia) * ''Corvus brachyrhynchos'' – American crow (United States, southern Canada, northern Mexico) * ''Corvus capensis'' – Cape crow or Cape rook (Eastern and southern Africa) * ''Corvus cornix'' – hooded crow (Northern and Eastern Europe and Northern Africa and Middle East) * ''Corvus corone'' – carrion crow (Europe and eastern Asia) *''Corvus culminatus'' – Indian jungle crow (South Asia) * ''Corvus edithae'' – Somali crow or dwarf raven (eastern Africa) * ''Corvus enca'' – slender-billed crow (Malaysia, Born ...

Port And Starboard
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brook Taylor
Brook Taylor (18 August 1685 – 29 December 1731) was an English mathematician best known for creating Taylor's theorem and the Taylor series, which are important for their use in mathematical analysis. Life and work Brook Taylor was born in Edmonton (former Middlesex). Taylor was the son of John Taylor, MP of Patrixbourne, Kent and Olivia Tempest, the daughter of Sir Nicholas Tempest, Baronet of Durham. He entered St John's College, Cambridge, as a fellow-commoner in 1701, and took degrees in LL.B. in 1709 and LL.D. in 1714. Taylor studied mathematics under John Machin and John Keill, leading to Taylor obtaining a solution to the problem of "center of oscillation." Taylor's solution remained unpublished until May 1714, when his claim to priority was disputed by Johann Bernoulli. Taylor's ''Methodus Incrementorum Directa et Inversa'' (1715) ("Direct and Indirect Methods of Incrementation") added a new branch to higher mathematics, called "calculus of finite dif ...
