Amratian Culture
The Amratian culture, also called Naqada I, was an archaeological culture of prehistoric Upper Egypt. It lasted approximately from 4000 to 3500 BC. Overview The Amratian culture is named after the archaeological site of el-Amra, located around south of Badari in Upper Egypt. El-Amra was the first site where this culture group was found without being mingled with the later Gerzeh culture (Naqada II). However, this period is better attested at the Nagada site, thus it also is referred to as the Naqada I culture. Black-topped pottery continued to be produced, but white cross-line pottery, a type which has been decorated with close parallel white lines being crossed by another set of close parallel white lines, begins to be produced during this time. The Amratian falls between S.D. 30 and 39 in Flinders Petrie's sequence dating system. The Amratians possessed slaves and constructed rowboats of bundled papyrus in which they could sail the Nile.

El-Amrah, Egypt
El-Amrah is a site about south of Badari, Upper Egypt. Archaeological discoveries in 1901 at El-Amrah, were the basis of what is now known as the Amratian culture, a Naqada I culture of predynastic Upper Egypt Upper Egypt ( ar, صعيد مصر ', shortened to , , locally: ; ) is the southern portion of Egypt and is composed of the lands on both sides of the Nile that extend upriver from Lower Egypt in the north to Nubia in the south.

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 crea ...

Adobe
Adobe ( ; ) is a building material made from earth and organic materials. is Spanish for '' mudbrick''. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. Adobe architecture has been dated to before 5,100 B.C. Description Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured weighing about ; in other contexts the size is weig ...

Naxos
Naxos (; el, Νάξος, ) is a Greek island and the largest of the Cyclades. It was the centre of archaic Cycladic culture. The island is famous as a source of emery, a rock rich in corundum, which until modern times was one of the best abrasives available. The largest town and capital of the island is Chora or Naxos City, with 7,374 inhabitants (2011 census). The main villages are Filoti, Apiranthos, Vivlos, Agios Arsenios, Koronos and Glynado. Geography Climate Naxos experiences a Mediterranean climate, with relatively mild winters and warm summers. The Köppen Climate Classification subtype for this climate is " Csa". (Mediterranean Climate). Inland areas of the island are much wetter and cooler in winter. Mythic Naxos According to Greek mythology, the young Zeus was raised in a cave on Mt. Zas ("''Zas''" meaning "''Zeus''"). Homer mentions " Dia"; literally the sacred island "of the Goddess". Károly Kerényi explains: One legend has it that ...

Emery (rock)
Emery, or corundite, is a dark granular rock used to make abrasive powder. It largely consists of corundum ( aluminium oxide), mixed with other minerals such as the iron-bearing spinels, hercynite, and magnetite, and also rutile ( titania). Industrial emery may contain a variety of other minerals and synthetic compounds such as magnesia, mullite, and silica. It is black or dark grey in colour, less dense than translucent-brown corundum with a specific gravity of between 3.5 and 3.8. Because it can be a mixture of minerals, no definite Mohs hardness can be assigned: the hardness of corundum is 9 and that of some spinel-group minerals is near 8, but the hardness of others such as magnetite is near 6. Crushed or naturally eroded emery (known as ''black sand'') is used as an abrasive—for example, on emery boards and emery cloth. It is also used as a traction enhancer in asphalt and tarmac mixtures. Turkey and Greece are the main suppliers of the world's emery. These tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paros
Paros (; el, Πάρος; Venetian: ''Paro'') is a Greek island in the central Aegean Sea. One of the Cyclades island group, it lies to the west of Naxos, from which it is separated by a channel about wide. It lies approximately south-east of Piraeus. The Municipality of Paros includes numerous uninhabited offshore islets totaling of land. Its nearest neighbor is the municipality of Antiparos, which lies to its southwest. In ancient Greece, the city-state of Paros was located on the island. Historically, Paros was known for its fine white marble, which gave rise to the term "Parian" to describe marble or china of similar qualities. Today, abandoned marble quarries and mines can be found on the island, but Paros is primarily known as a popular tourist spot. Geography Paros' geographic co-ordinates are 37° N. latitude, and 25° 10' E. longitude. The area is . Its greatest length from N.E. to S.W. is , and its greatest breadth . The island is of a round, plump-pear shape, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; R. S. P. Beekes has suggested that a " Pre-Greek origin is probable". This stem is also the ancestor of the English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French , most other European languages (with words like "marmoreal") more closely resemble the original Ancient Greek. Physical origins Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byblos
Byblos ( ; gr, Βύβλος), also known as Jbeil or Jubayl ( ar, جُبَيْل, Jubayl, locally ; phn, 𐤂𐤁𐤋, , probably ), is a city in the Keserwan-Jbeil Governorate of Lebanon. It is believed to have been first occupied between 8800 and 7000BC and continuously inhabited since 5000BC, making it one of the oldest continuously inhabited cities in the world. During its history, Byblos was part of numerous civilizations, including Egyptian, Phoenician, Assyrian, Persian, Hellenistic, Roman, Fatimid, Genoese, Mamluk and Ottoman. The city is a UNESCO World Heritage Site. It was in ancient Byblos that the Phoenician alphabet, likely the ancestor of the Greek, Latin and all other Western alphabets, was developed. Etymology Byblos appears as ''Kebny'' in Egyptian hieroglyphic records going back to the 4th-dynasty pharaoh Sneferu (BC) and as () in the Akkadian cuneiform Amarna letters to the 18th-dynasty pharaohs and IV. In the 1stmillenniumBC, its n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oasis
In ecology, an oasis (; ) is a fertile area of a desert or semi-desert environment'ksar''with its surrounding feeding source, the palm grove, within a relational and circulatory nomadic system.” The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both north–south and east–west Trans-Saharan trade, trade in the Sahara Desert. The location of oases also informed the Darb El Arba'īn trade route from Sudan to Egypt, as well as the caravan route from the Niger River to Tangier, Morocco. The Silk Road “traced its course from water hole to water hole, relying on oasis communities such as Turpan in China and Sa ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloro ...
