List Of Largest Monoliths In The World
This is a list of monoliths organized according to the size of the largest block of stone on the site. A monolith is a large stone which has been used to build a structure or monument, either alone or together with other stones. In this list at least one colossal stone over ten tons has been moved to create the structure or monument. In most cases ancient civilizations had little, if any, advanced technology that would help them move these monoliths. The most notable exception is that of the ancient Greeks and Romans, who had cranes and treadwheels to help lift colossal stones (see list of ancient Greek and Roman monoliths). This article also includes a list of modern experimental archaeology efforts to move colossal stones using technologies available to the respective ancient civilizations. Most of these weights are based on estimates by published scholars; however, there have been numerous false estimates of many of these stones presented as fact. To help recognize exaggerati ...

SRI International
SRI International (SRI) is an American nonprofit scientific research institute and organization headquartered in Menlo Park, California. The trustees of Stanford University established SRI in 1946 as a center of innovation to support economic development in the region. The organization was founded as the Stanford Research Institute. SRI formally separated from Stanford University in 1970 and became known as SRI International in 1977. SRI performs client-sponsored research and development for government agencies, commercial businesses, and private foundations. It also licenses its technologies, forms strategic partnerships, sells products, and creates spin-off companies. SRI's headquarters are located near the Stanford University campus. SRI's annual revenue in 2014 was approximately $540 million, which tripled from 1998 under the leadership of Curtis Carlson. In 1998, the organization was on the verge of bankruptcy when Carlson took over as CEO. Over the next sixteen years wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post-Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baalbek
Baalbek (; ar, بَعْلَبَكّ, Baʿlabakk, Syriac-Aramaic: ܒܥܠܒܟ) is a city located east of the Litani River in Lebanon's Beqaa Valley, about northeast of Beirut. It is the capital of Baalbek-Hermel Governorate. In Greek and Roman times Baalbek was also known as Heliopolis (, Greek for "Sun City"). In 1998 Baalbek had a population of 82,608, mostly Shia Muslims, followed by Sunni Muslims and Christians. It is home to the Baalbek temple complex which includes two of the largest and grandest Roman temple ruins: the Temple of Bacchus and the Temple of Jupiter. It was inscribed in 1984 as an UNESCO World Heritage site. Name A few miles from the swamp from which the Litani (the classical Leontes) and the Asi (the upper Orontes) flow, Baalbek may be the same as the ''manbaa al-nahrayn'' ("Source of the Two Rivers"), the abode of El in the Ugaritic Baal Cycle discovered in the 1920s and a separate serpent incantation. Baalbek was called Heliopolis during the Roma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lebanon
Lebanon ( , ar, لُبْنَان, translit=lubnān, ), officially the Republic of Lebanon () or the Lebanese Republic, is a country in Western Asia. It is located between Syria to the north and east and Israel to the south, while Cyprus lies to its west across the Mediterranean Sea; its location at the crossroads of the Mediterranean Basin and the Arabian hinterland has contributed to its rich history and shaped a cultural identity of religious diversity. It is part of the Levant region of the Middle East. Lebanon is home to roughly six million people and covers an area of , making it the second smallest country in continental Asia. The official language of the state is Arabic, while French is also formally recognized; the Lebanese dialect of Arabic is used alongside Modern Standard Arabic throughout the country. The earliest evidence of civilization in Lebanon dates back over 7000 years, predating recorded history. Modern-day Lebanon was home to the Phoenicians, a m ...

Baalbek Stones
The Baalbek Stones are six massive Roman worked stone blocks in Baalbek (ancient Heliopolis), Lebanon, characterised by a megalithic gigantism unparallelled in antiquity. The smallest three are part of a podium wall in the Roman complex of the Temple of Jupiter Baal (Heliopolitan Zeus) on Tel Baalbek and are known as the "Trilithon". Each of these is estimated at about . The remaining three are Roman monoliths, not part of a larger structure, conventionally known as the "Stone of the Pregnant Woman" (estimated at 1,000 t), the "Stone of the South" (est. 1,242 t), and the "Forgotten Stone" (est. 1,650 t). These are, in reverse order, the first, third, and tied fifth largest known stones ever quarried in human history. They are believed to have been intended for the nearby Jupiter Baal complex, possibly as an addition to the Trilithon; but, perhaps due to their size, they were never removed from their quarry. They have not been used since their extraction in ancient times. Nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assuan 07
Aswan (, also ; ar, أسوان, ʾAswān ; cop, Ⲥⲟⲩⲁⲛ ) is a city in Southern Egypt, and is the capital of the Aswan Governorate. Aswan is a busy market and tourist centre located just north of the Aswan Dam on the east bank of the Nile at the first cataract. The modern city has expanded and includes the formerly separate community on the island of Elephantine. Aswan includes five monuments within the UNESCO World Heritage Site of the Nubian Monuments from Abu Simbel to Philae (despite Aswan being neither Nubian, nor between Abu Simbel and Philae); these are the Old and Middle Kingdom tombs of Qubbet el-Hawa, the town of Elephantine, the stone quarries and Unfinished Obelisk, the Monastery of St. Simeon and the Fatimid Cemetery. The city's Nubian Museum is an important archaeological center, containing finds from the International Campaign to Save the Monuments of Nubia prior to the Aswan Dam's flooding of all of Lower Nubia. The city is part of the UNESCO Crea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalts
Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are thick sequenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
