Tangendorf Disc Brooch
The Tangendorf disc brooch (german: Scheibenfibel von Tangendorf) is an Iron Age fibula from the 3rd century AD, which was dug up in 1930 from the sand of a Bronze Age tumulus near Tangendorf, Toppenstedt, Harburg, Lower Saxony, Germany. The front of the elaborately crafted garment fibula is decorated with a rear-facing four-legged animal, probably a dog or a deer. It is one of Harburg's most important finds from the period of the Roman Empire, and is in the permanent exhibition of the Archaeological Museum Hamburg in Harburg, Hamburg. Discovery The Tangendorf disc brooch was found in 1930 in a tumulus (at ) on a parcel of land known as ' (in the black dorn), on the outer northwest corner of Tangendorf. While digging off sand from a Bronze Age grave mound in his field, farmer Heinrich Wille found the fibula together with a bronze hair clip (German: ) and a bronze spear blade. The hair clip and the spear blade were passed to the Helms-Museum; however, the brooch was left w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooch
A brooch (, also ) is a decorative jewelry item designed to be attached to garments, often to fasten them together. It is usually made of metal, often silver or gold or some other material. Brooches are frequently decorated with vitreous enamel, enamel or with gemstones and may be solely for jewellery, ornament or serve a practical function as a clothes fastener. The earliest known brooches are from the Bronze Age. As fashions in brooches changed rather quickly, they are important chronological indicators. In archaeology, ancient European brooches are usually referred to by the Latin term Fibula (brooch), fibula. Ancient brooches Brooches were known as Fibula (brooch), fibula (plural fibulae) prior to the Middle Ages. These decorative items, used as clothes fasteners, were first crafted in the Bronze Age. In Europe, during the Iron Age, metalworking technology had advanced dramatically. The newer techniques of casting, metal bar-twisting and wire making were the basis for many n ...

Dating Methodologies In Archaeology
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred. These methods are typically identified as absolute, which involves a specified date or date range, or relative, which refers to dating which places artifacts or events on a timeline relative to other events and/or artifacts. Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers. Absolute ...

Typology (archaeology)
In archaeology, a typology is the result of the classification of things according to their physical characteristics. The products of the classification, i.e. the classes, are also called types. Most archaeological typologies organize portable artifacts into types, but typologies of larger structures, including buildings, field monuments, fortifications or roads, are equally possible. A typology helps to manage a large mass of archaeological data. According to Doran and Hodson, "this superficially straightforward task has proved one of the most time consuming and contentious aspects of archaeological research". Philosophical background Typology is based on a view of the world familiar from Plato's metaphysics called essentialism. Essentialism is the idea that the world is divided into real, discontinuous and immutable "kinds". This idea is the basis for most typological constructions particularly of stone artefacts where essential forms are often thought of as "mental templates" ...

Ivory
Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. Besides natural ivory, ivory can also be produced synthetically, hence (unlike natural ivory) not requiring the retrieval of the material from animals. Tagua nuts can also be carved like ivory. The trade of finished goods of ivory products has its origins in the Indus Valley. Ivory is a main product that is seen in abundance and was used for trading in Harappan civilization. Finished ivory pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granulation (jewellery)
Granulation is a jewellery manufacturing technique whereby a surface is covered in spherules or granules of precious metal. The technique is thought to have its origins in Sumer about 5,000 years ago. This technique then spread to southern Europe during the orientalizing period, also through the role of Phoenicians, who had founded colonies in Sardinia, Sicily and Spain, or Near Eastern craftsmen. In the first millennium B.C. the technique was used by Etruscans living in present-day Italy. Greek craftsmen also employed the technique, but it was the work coming from Etruria which became famous, in part due to the mysteries surrounding the process. Methods This technique is notoriously difficult and mysterious in the jewelry world. So much that Ancient Greeks had young children place granules due to the extreme patience and near perfect eyesight needed to place each granule onto the base of the metal being fused. Granulation may be employed in three elaborate ways: the outline st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tin Pest
Tin is a chemical element with the symbol Sn (from la, stannum) and atomic number 50. Tin is a silvery-coloured metal. Tin is soft enough to be cut with little force and a bar of tin can be bent by hand with little effort. When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in the solid state. Pure tin after solidifying presents a mirror-like appearance similar to most metals. In most tin alloys (such as pewter) the metal solidifies with a dull gray color. Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, . Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element on Earth and has, with 10 stable isotopes, the largest n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allotropy
Allotropy or allotropism () is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements. Allotropes are different structural modifications of an element: the atoms of the element are bonded together in a different manner. For example, the allotropes of carbon include diamond (the carbon atoms are bonded together to form a cubic lattice of tetrahedra), graphite (the carbon atoms are bonded together in sheets of a hexagonal lattice), graphene (single sheets of graphite), and fullerenes (the carbon atoms are bonded together in spherical, tubular, or ellipsoidal formations). The term ''allotropy'' is used for elements only, not for compounds. The more general term, used for any compound, is polymorphism, although its use is usually restricted to solid materials such as crystals. Allotropy refers only to different forms of an element within the same physical phase (the state of matter, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Cremation
Cremation is a method of Disposal of human corpses, final disposition of a Cadaver, dead body through Combustion, burning. Cremation may serve as a funeral or post-funeral rite and as an alternative to burial. In some countries, including India and Nepal, cremation on an Pyre, open-air pyre is an ancient tradition. Starting in the 19th century, cremation was introduced or reintroduced into other parts of the world. In modern times, cremation is commonly carried out with a Crematorium, closed furnace (cremator), at a crematorium. Cremation leaves behind an average of 2.4 kg (5.3 lbs) of remains known as "ashes" or "cremains". This is not all ash but includes unburnt fragments of bone mineral, which are commonly ground into powder. They do not constitute a health risk and may be buried, interred in a memorial site, retained by relatives or scattered in various ways. History Ancient Cremation dates from at least 17,000 years ago in the archaeological record, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excavation (archaeology)
In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or "dig" is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years. Excavation involves the recovery of several types of data from a site. This data includes artifacts (portable objects made or modified by humans), features (non-portable modifications to the site itself such as post molds, burials, and hearths), ecofacts (evidence of human activity through organic remains such as animal bones, pollen, or charcoal), and archaeological context (relationships among the other types of data).Kelly&Thomas (2011). ''Archaeology: down to earth'' (4th ed.). Belmont, Calif.: Wadsworth, Cengage Learning. Before excavating, the presence or absence of archaeological remains can often be suggested by, non-intrusive remote sensing, such as ground-penetrating radar. Basic informat ...
