John Doubleday (restorer)
John Doubleday (about 1798 – 25January 1856) was a British craftsperson, restorer, and dealer in antiquities who was employed by the British Museum for the last 20 years of his life. He undertook several duties for the museum, not least as a witness in criminal trials, but was primarily their specialist restorer, perhaps the first person to hold the position. He is best known for his 1845 restoration of the severely-damaged Roman Portland Vase, an accomplishment that places him at the forefront of his profession at the time. While at the British Museum, Doubleday also dealt in copies of coins, medals, and ancient seals. His casts in coloured sulphur and in white metal of works in both national and private collections, allowed smaller collections to hold copies at a fraction of the price that the originals would command. Thousands of his copies entered the collections of institutions and individuals. Yet the accuracy he achieved led to confusion with the originals; after his ...

Portland Vase
The Portland Vase is a Roman cameo glass vase, which is dated to between AD 1 and AD 25, though low BC dates have some scholarly support. It is the best known piece of Roman cameo glass and has served as an inspiration to many glass and porcelain makers from about the beginning of the 18th century onwards. It is first recorded in Rome in 1600–1601, and since 1810 has been in the British Museum in London. It was bought by the museum in 1945 (GR 1945,0927.1) and is normally on display in Room 70. The vase measures about high and . It is made of violet-blue glass, and surrounded with a single continuous white glass cameo making two distinct scenes, depicting seven human figures, plus a large snake, and two bearded and horned heads below the handles, marking the break between the scenes. The bottom of the vase was a cameo glass disc, also in blue and white, showing a head, presumed to be of Paris or Priam on the basis of the Phrygian cap it wears. This roundel clearly does not ...

William Andrew Oddy
William Andrew Oddy, (born 6 January 1942) is a former Keeper of Conservation at the British Museum, notable for his publications on artefact conservation and numismatics, and for the development of the Oddy test. In 1996 he was awarded the Forbes Prize "for outstanding work in the field of conservation" by the International Institute for Conservation, and gave the attendant Forbes Lecture that year in Copenhagen. He retired in 2002 and was appointed as an Officer of the Order of the British Empire the same year. Early life William Andrew Oddy was born on 6 January 1942 in Bradford and spent his childhood in the nearby township of Baildon. He was the first son of William Tingle Oddy, then serving in the Auxiliary Fire Service for the duration of World War II, and Hilda Florence Oddy (née Dalby). He attended Sandal Primary School in Baildon and Bradford Grammar School. It was during these years that he developed an interest in archaeology after having visited the excavation ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Thomas Newton
Sir Charles Thomas Newton (16 September 1816 – 28 November 1894) was a British archaeologist. He was made KCB in 1887. Life He was born in 1816, the second son of Newton Dickinson Hand Newton, vicar of Clungunford, Shropshire, and afterwards of Bredwardine, Herefordshire. He was educated at Shrewsbury School (then under Samuel Butler), and at Christ Church, Oxford (matriculating 17 Oct. 1833), where he graduated B.A. in 1837 and M.A. in 1840. Already in his undergraduate days Newton (as his friend and contemporary, John Ruskin, tells in ''Præterita'') was giving evidence of his natural bent; the scientific study of classical archaeology, which Winckelmann had set on foot in Germany, was in England to find its worthy apostle in Newton. In 1840, contrary to the wishes of his family, he entered the British Museum as an assistant in the department of antiquities. As a career the museum, as it then was, can have presented but few attractions to a young man; but the depar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pottery
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural "potteries"). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were ...

Samuel Birch
Samuel Birch (3 November 1813 – 27 December 1885) was a British Egyptologist and antiquary. Biography Birch was the son of a rector at St Mary Woolnoth, London. He was educated at Merchant Taylors' School. From an early age, his manifest tendency to the study of out-of-the-way subjects well suited his later interest in archaeology. After brief employment in the Record Office, he obtained, in 1836, an appointment to the antiquities department of the British Museum. The appointment was due to his knowledge of Chinese, which was unusual at that time. He soon broadened his research to Egyptian. When the cumbrous department came to be divided, he was appointed to head the Egyptian and Assyrian branch. In the latter language he had assistance, but for many years there was only one other person in the institution, in a different department, who knew anything of ancient Egyptian. The entire arrangement of the department devolved upon Birch. He found time nevertheless for Egyptolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assyria
Assyria (Neo-Assyrian cuneiform: , romanized: ''māt Aššur''; syc, ܐܬܘܪ, ʾāthor) was a major ancient Mesopotamian civilization which existed as a city-state at times controlling regional territories in the indigenous lands of the Assyrians from the 21st century BC to the 14th century BC, then to a territorial state, and eventually an empire from the 14th century BC to the 7th century BC. Spanning from the early Bronze Age to the late Iron Age, modern historians typically divide ancient Assyrian history into the Early Assyrian ( 2600–2025 BC), Old Assyrian ( 2025–1364 BC), Middle Assyrian ( 1363–912 BC), Neo-Assyrian (911–609 BC) and post-imperial (609 BC– AD 630) periods, based on political events and gradual changes in language. Assur, the first Assyrian capital, was founded 2600 BC but there is no evidence yet discovered that the city was independent until the collapse of the Third Dynasty of Ur in the 21st century BC, when a line of independent kin ...

Babylonia
Babylonia (; Akkadian: , ''māt Akkadī'') was an ancient Akkadian-speaking state and cultural area based in the city of Babylon in central-southern Mesopotamia (present-day Iraq and parts of Syria). It emerged as an Amorite-ruled state c. 1894 BCE. During the reign of Hammurabi and afterwards, Babylonia was called "the country of Akkad" (''Māt Akkadī'' in Akkadian), a deliberate archaism in reference to the previous glory of the Akkadian Empire. It was often involved in rivalry with the older state of Assyria to the north and Elam to the east in Ancient Iran. Babylonia briefly became the major power in the region after Hammurabi ( fl. c. 1792–1752 BCE middle chronology, or c. 1696–1654 BCE, short chronology) created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire. The Babylonian Empire rapidly fell apart after the death of Hammurabi and reverted to a small kingdom. Like Assyria, the Babylonian state retained ...

Oxidation
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogenation, C=C (and other) bonds ar ...

Nimrud
Nimrud (; syr, ܢܢܡܪܕ ar, النمرود) is an ancient Assyrian city located in Iraq, south of the city of Mosul, and south of the village of Selamiyah ( ar, السلامية), in the Nineveh Plains in Upper Mesopotamia. It was a major Assyrian city between approximately 1350 BC and 610 BC. The city is located in a strategic position north of the point that the river Tigris meets its tributary the Great Zab.Brill's Encyclopedia of Islam 1913-36 p.923 The city covered an area of .

Acid
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Informa ...
