Poggio Colla
Poggio Colla is an Etruscan archaeological site located near the town of Vicchio in Tuscany, Italy. History The site of Poggio Colla preserved undisturbed habitation layers related to the Etruscan civilization and appears to have been inhabited by Etruscans at least as early as 7th century BCE and was abandoned or destroyed in the late 3rd century BCE. The site suffered a violent destruction and was rebuilt during the Hellenistic period. Excavation The first excavations at Poggio Colla were directed by Francesco Nicosia from 1968 to 1972. From 1995 to 2012, the site was excavated annually by the Mugello Valley Archaeological Project (MVAP) under the direction of Gregory Warden and Michael Thomas; MVAP is sponsored by Southern Methodist University and the University of Pennsylvania. Excavations have revealed fortification walls, a necropolis area, and the remains of an archaic monumental building (possibly, a temple). Research The faunal remains recovered from Poggio Colla pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acropolis
An acropolis was the settlement of an upper part of an ancient Greek city, especially a citadel, and frequently a hill with precipitous sides, mainly chosen for purposes of defense. The term is typically used to refer to the Acropolis of Athens, yet every Greek city had an acropolis of its own. Acropoloi were used as religious centers and places of worship, forts, and places in which the royal and high-status resided. Acropolises became the nuclei of large cities of classical ancient times, and served as important centers of a community. Some well-known acropoloi have become the centers of tourism in present-day, and, especially, the Acropolis of Athens has been a revolutionary center for the studies of ancient Greece since the Mycenaean period. Many of them have become a source of revenue for Greece, and represent some great technology during the period. Origin An acropolis is defined by the Greek definition of ἀκρόπολις, akropolis; from akros (άκρος) or (άκ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populated Places Established In The 7th Century BC
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with ind ...

Former Populated Places In Italy
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Feature (archaeology)
In archaeological excavation, a feature is a collection of one or more contexts representing some human non-portable activity, such as a hearth or wall. Features serve as an indication that the area in which they are found has been interfered with in the past, usually by humans. Features are distinguished from artifacts in that they cannot be separated from their location without changing their form. Artifacts are portable, while features are non-portable. Artifacts and features can both be made from any available material, with the primary distinction being portability. Features and artifacts differ from ecofacts. Ecofacts are natural remains, such as plants and animals. Types Features are categorized by the time period, as either historic or prehistoric. Prehistoric archaeology refers to the time in history before human life was recorded or documented, while historic archaeology refers to the time period where there was a documented human past.

Paleoethnobotany
Paleoethnobotany (also spelled palaeoethnobotany), or archaeobotany, is the study of past human-plant interactions through the recovery and analysis of ancient plant remains. Both terms are synonymous, though paleoethnobotany (from the Greek words ''palaios'' αλαιόςmeaning ancient, ''ethnos'' θνοςmeaning race or ethnicity, and ''votano'' ότανοmeaning plants) is generally used in North America and acknowledges the contribution that ethnographic studies have made towards our current understanding of ancient plant exploitation practices, while the term archaeobotany (from the Greek words ''archaios'' ρχαίοςmeaning ancient and ''votano'') is preferred in Europe and emphasizes the discipline's role within archaeology. As a field of study, paleoethnobotany is a subfield of environmental archaeology. It involves the investigation of both ancient environments and human activities related to those environments, as well as an understanding of how the two co-evolv ...

Grog (clay)
Grog, also known as firesand and chamotte, is a raw material usually made from crushed and ground potsherds, reintroduced back into crude clay to temper it before making ceramic ware. It has a high percentage of silica and alumina. It is normally available as a powder or chippings, and is an important ingredient in Coade stone. Production It can be produced by firing selected fire clays to high temperature before grinding and screening to specific particle sizes. Another method makes it from pitchers. The particle size distribution is generally coarser in size than the other raw materials used to prepare clay bodies. It tends to be porous and have low density. Properties Grog is composed of 40% minimum alumina, 30% minimum silica, 4% maximum iron(III) oxide, up to 2% calcium oxide and magnesium oxide combined.. Its melting point is approximately . Its boiling point is over . Its water absorption is maximum 7%. Its thermal expansion coefficient is 5.2 mm/m and thermal ...

Feldspar
Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight. Feldspars crystalize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Compositions The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: * potassium feldspar (K-spar) ...

Sherd
In archaeology, a sherd, or more precisely, potsherd, is commonly a historic or prehistoric fragment of pottery, although the term is occasionally used to refer to fragments of stone and glass vessels, as well. Occasionally, a piece of broken pottery may be referred to as a shard. While the spelling shard is generally reserved for referring to fragments of glass vessels, the term does not exclude pottery fragments. The etymology is connected with the idea of breakage, from Old English ''sceard'', related to Old Norse ''skarð'', "notch", and Middle High German ''schart'', "notch". A sherd or potsherd that has been used by having writing painted or inscribed on it can be more precisely referred to as an ostracon An ostracon (Greek: ''ostrakon'', plural ''ostraka'') is a piece of pottery, usually broken off from a vase or other earthenware vessel. In an archaeological or epigraphical context, ''ostraca'' refer to sherds or even small pieces of ston .... The analysis of ...

Thermogravimetric Analysis
Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction). Thermogravimetric analyzer Thermogravimetric analysis (TGA) is conducted on an instrument referred to as a thermogravimetric analyzer. A thermogravimetric analyzer continuously measures mass while the temperature of a sample is changed over time. Mass, temperature, and time are considered base measurements in thermogravimetric analysis while many additional measures may be derived from these three base measurements. A typical thermogravimetric analyzer consists of a precision balance with a sample pan located inside a furnace with a programmab ...

Petrography
Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis. Petrographic descriptions start with the field notes at the outcrop and include macroscopic description of hand specimens. The most important petrographer's tool is the petrographic microscope. The detailed analysis of minerals by optical mineralogy in thin section and the micro-texture and structure are critical to understanding the origin of the rock. Electron microprobe or atom probe tomography analysis of individual grains as well as whole rock chemical analysis by atomic absorption, X-ray fluorescence, and laser-induced breakdown spectroscopy are used in a modern petrographic lab. Individual mineral grains from a rock sample may also be analyze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
