Firedog
An andiron, firedog, fire-dog, fire dog or iron-dog is a bracket support, normally one of a pair, on which logs are laid for burning in an open fireplace, so that air may circulate under the firewood, allowing better burning and less smoke. They generally consist of a tall vertical element at the front, with at least two legs. This stops the logs from rolling out into the room, and may be highly decorative. The other element is one or more low horizontal pieces stretching back into the fireplace and serving to hold the logs off the bottom of the fireplace. An andiron is sometimes called a ''dog'' or ''dog-iron''. Before the Renaissance, European andirons, almost invariably made entirely of iron, were of comparatively plain design. Indeed, andirons and Fireplace fireback, firebacks were one of the first types of object commonly made in cast iron (introduced to the West in the 15th century), a trend which in England began in the 1540s: until the nineteenth century cast iron ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Algardi Firedogs
The Algardi Firedogs (French - ''chenets de l'Algarde'') are two small bronze sculptural groups, individually entitled ''Jupiter holding his thunderbolt, seated on a terrestrial globe supported by three Titans'' and ''Juno, Jupiter's wife carried by the winds''. Originals The originals were commissioned as the fronts of andirons or firedogs from the Roman sculptor Alessandro Algardi for Philip IV of Spain by Diego Velázquez in 1650 whilst he was Spanish ambassador to the Italian states, and he ordered four bronzes symbolizing the four elements of the court of Spain. Though they were incomplete on his death and had to be completed by his pupils. He had only completed the first two in a planned set of four before his death and so the other two (''Neptune carried by the waters'' and ''Cybele carried by the earth'') were produced by his children. Philip did not use them as firedogs but as decorative elements for the garden of his Aranjuez Palace. France Other 17th century foundrie ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ...

Dog (engineering)
In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make ...

Heraldic
Heraldry is a discipline relating to the design, display and study of armorial bearings (known as armory), as well as related disciplines, such as vexillology, together with the study of ceremony, rank and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on a shield, helmet and crest, together with any accompanying devices, such as supporters, badges, heraldic banners and mottoes. Although the use of various devices to signify individuals and groups goes back to antiquity, both the form and use of such devices varied widely, as the concept of regular, hereditary designs, constituting the distinguishing feature of heraldry, did not develop until the High Middle Ages. It is often claimed that the use of helmets with face guards during this period made it difficult to recognize one's commanders in the field when large armies gathered toge ...

Porridge
Porridge is a food made by heating, soaking or boiling ground, crushed or chopped starchy plants, typically grain, in milk or water. It is often cooked or served with added flavourings such as sugar, honey, fruit, or syrup to make a sweet cereal, or it can be mixed with spices, meat, or vegetables to make a Savoury (dish), savoury dish. It is usually served hot in a bowl, depending on its consistency. Oat porridge, (known as oatmeal in North America) is one of the most common types of porridge. Gruel is a thinner version of porridge and congee is a savoury variation of porridge of Asian cuisine, Asian origin. Type of grains The term "porridge" is used in British English (Britain, Ireland, Australia and New Zealand) specifically for oatmeal. This is a hot mixture of oatmeal or oats slowly cooked with water or milk. It is typically eaten for breakfast by itself or with other ingredients, including salt, sugar, fruit, milk, cream, or butter. Other grains used for porridge include ...

Ceramic
A ceramic is any of the various hard, brittle, heat-resistant, and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. The earliest ceramics made by humans were fired clay bricks used for building house walls and other structures. Other pottery objects such as pots, vessels, vases and figurines were made from clay, either by itself or mixed with other materials like silica, hardened by sintering in fire. Later, ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates. Ceramics now include domestic, industrial, and building products, as well as a wide range of materials developed for use in advanced ceramic engineering, such as semiconductors. The word '' ceramic'' comes from the Ancient Greek word (), meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mythological
Myth is a genre of folklore consisting primarily of narratives that play a fundamental role in a society. For scholars, this is very different from the vernacular usage of the term "myth" that refers to a belief that is not true. Instead, the veracity of a myth is not a defining criterion. Myths are often endorsed by religious (when they are closely linked to religion or spirituality) and secular authorities. Many societies group their myths, legends, and history together, considering myths and legends to be factual accounts of their remote past. In particular, creation myths take place in a primordial age when the world had not achieved its later form. Origin myths explain how a society's customs, institutions, and taboos were established and sanctified. National myths are narratives about a nation's past that symbolize the nation's values. There is a complex relationship between recital of myths and the enactment of rituals. Etymology The word "myth" comes from Ancient ...

Fleur-de-lis
The ''fleur-de-lis'', also spelled ''fleur-de-lys'' (plural ''fleurs-de-lis'' or ''fleurs-de-lys''), is a common heraldic charge in the (stylized) shape of a lily (in French, and mean and respectively). Most notably, the ''fleur-de-lis'' is depicted on the flag of Quebec and on the traditional coat of arms of France that was used from the High Middle Ages until the French Revolution in 1792, and then again in brief periods in the 19th century. This design still represents France and the House of Bourbon in the form of Heraldry#Marshalling, marshalling in the arms of Coat of arms of Spain, Spain, Coat of arms of Quebec, Quebec, and Coat of arms of Canada, Canada — for example. Other European nations have also employed the symbol. The ''fleur-de-lis'' became "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic", especially in French heraldry. The Mary, mother of Jesus, Virgin Mary and Saint Joseph are among saints often depicted wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sphinx
A sphinx ( ; , ; or sphinges ) is a mythical creature with the head of a human, the body of a lion, and the wings of an eagle. In Culture of Greece, Greek tradition, the sphinx is a treacherous and merciless being with the head of a woman, the haunches of a lion, and the wings of a bird. According to Greek myth, she challenges those who encounter her to answer a riddle, and kills and eats them when they fail to solve the riddle. This deadly version of a sphinx appears in the myth and drama of Oedipus. In Egyptian mythology, in contrast, the sphinx is typically depicted as a man (an androsphinx ()), and is seen as a benevolent representation of strength and ferocity, usually of a pharaoh. Unlike Greek or Levantine/Mesopotamian ones, Egyptian sphinxes were not winged. Both the Greek and Egyptian sphinxes were thought of as guardians, and statues of them often flank the entrances to temples. During the Renaissance, the sphinx enjoyed a major revival in European decorative art. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
