Homeric Minimum
The Homeric Minimum is a grand solar minimum that took place between 2,800 and 2,550 years Before Present (c. 800–600 BC). It appears to coincide with, and have been the cause of, a phase of climate change (general concept), climate change at that time, which involved a wetter Western Europe and drier eastern Europe. This had far-reaching effects on human civilization, some of which may be recorded in Greek mythology and the Old Testament. Solar phenomenon The Homeric Minimum is a persistent and deep solar minimum that took place between 2,800 and 2,550 years Before Present, starting around 830 Before Common Era, BCE and resembling the Spörer Minimum. It is sometimes named "Great Solar Minimum". It has been subdivided into a stronger minimum at 2,750-2,635 years before present and a secondary minimum 2,614-2,594 years before present. The Homeric Minimum is sometimes considered to be part of a longer "Hallstattzeit" solar minimum between 705–200 BC that also includes a secon ...

Solar Minimum
Solar minimum is the regular period of least solar activity in the Sun's 11-year solar cycle. During solar minimum, sunspot and solar flare activity diminishes, and often does not occur for days at a time. On average, the solar cycle takes about 11 years to go from one solar minimum to the next, with duration observed varying from 9 to 14 years. The date of the minimum is described by a smoothed average over 12 months of sunspot activity, so identifying the date of the solar minimum usually can only happen 6 months after the minimum takes place. Solar minimum is contrasted with the solar maximum, when hundreds of sunspots may occur. Solar minimum and solar maximum Solar minima and maxima are the two extremes of the Sun's 11-year and 400-year activity cycle. At a maximum, the Sun is peppered with sunspots, solar flares erupt, and the Sun hurls billion-ton clouds of electrified gas into space. Sky watchers may see more auroras, and space agencies must monitor radiation storms for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Age Cold Epoch
The Iron Age Cold Epoch (also referred to as Iron Age climate pessimum or Iron Age neoglaciation) was a period of unusually cold climate in the North Atlantic region, lasting from about 900 BC to about 300 BC, with an especially cold wave in 450 BC during the expansion of ancient Greece. It was followed by the Roman Warm Period (250 BC – 400 AD). Gill Plunkett and Graeme T.

Iberia
The Iberian Peninsula (), ** * Aragonese and Occitan: ''Peninsula Iberica'' ** ** * french: Péninsule Ibérique * mwl, Península Eibérica * eu, Iberiar penintsula also known as Iberia, is a peninsula in southwestern Europe, defining the westernmost edge of Eurasia. It is principally divided between Spain and Portugal, comprising most of their territory, as well as a small area of Southern France, Andorra, and Gibraltar. With an area of approximately , and a population of roughly 53 million, it is the second largest European peninsula by area, after the Scandinavian Peninsula. Name Greek name The word ''Iberia'' is a noun adapted from the Latin word "Hiberia" originating in the Ancient Greek word Ἰβηρία ('), used by Greek geographers under the rule of the Roman Empire to refer to what is known today in English as the Iberian Peninsula. At that time, the name did not describe a single geographical entity or a distinct population; the same name was us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Meerfelder Maar
The Meerfelder Maar is a maar by the village of Meerfeld not far from the town of Manderscheid in the Eifel in the German state of Rhineland-Palatinate. Formation The maar is at least 30,000 years old and, according to the more recent information, is probably even 40,000 years old. In 1978 the lake deposits were investigated in order to determine its exact age. Numerous borings have been carried out in the Meerfelder Maar right up to the present day. It was formed by a huge underground phreatomagmatic explosion that happened when hot magma rose and struck a water-laden layer of rock. The explosive evaporation of the water crushed the surrounding rock and threw some of it upwards. The resulting hollow filled up again with rock and a funnel-shaped sink-hole formed at the surface. The magma chamber, from which the magma rose, lies about 2,000 to 6,000 metres below the Meerfelder Maar. Structure The whole crater has a diameter of 1,400 metres from east to west and ...

Ezekiel
Ezekiel (; he, יְחֶזְקֵאל ''Yəḥezqēʾl'' ; in the Septuagint written in grc-koi, Ἰεζεκιήλ ) is the central protagonist of the Book of Ezekiel in the Hebrew Bible. In Judaism, Christianity, and Islam, Ezekiel is acknowledged as a Hebrew prophet. In Judaism and Christianity, he is also viewed as the 6th-century BCE author of the Book of Ezekiel, which reveals prophecies regarding the destruction of Jerusalem, and the restoration to the land of Israel. The name Ezekiel means "God is strong" or "God strengthens". In the Bible The author of the Book of Ezekiel presents himself as Ezekiel, the son of Buzi, born into a priestly (kohen) lineage. Apart from identifying himself, the author gives a date for the first divine encounter which he presents: "in the thirtieth year". Ezekiel describes his calling to be a prophet by going into great detail about his encounter with God and four "living creatures" with four wheels that stayed beside the creatures. Liv ...

Polar Lights
An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/ exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of accelerati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homer
Homer (; grc, Ὅμηρος , ''Hómēros'') (born ) was a Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Homer is considered one of the most revered and influential authors in history. Homer's ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Ithaca, back to his home after the fall of Troy. The poems are in Homeric Greek, also known as Epic Greek, a literary language which shows a mixture of features of the Ionic and Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems were originally transmitted orally. Homer's epic poems shaped aspects of ancient Greek culture and education, fostering ideals of heroism, glory, and honor. To Plato, Homer was simply the one who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Olympus
Mount Olympus (; el, Όλυμπος, Ólympos, also , ) is the highest mountain in Greece. It is part of the Olympus massif near the Thermaic Gulf of the Aegean Sea, located in the Olympus Range on the border between Thessaly and Macedonia, between the regional units of Larissa and Pieria, about southwest from Thessaloniki. Mount Olympus has 52 peaks and deep gorges. The highest peak, Mytikas (Μύτικας ''Mýtikas''), meaning "nose", rises to . It is one of the highest peaks in Europe in terms of topographic prominence. In Greek mythology, Olympus is the home of the Greek gods, on Mytikas peak. The mountain has exceptional biodiversity and rich flora. It has been a National Park, the first in Greece, since 1938. It is also a World Biosphere Reserve. Every year, thousands of visitors admire its fauna and flora, tour its slopes, and climb its peaks. Organized mountain refuges and various mountaineering and climbing routes are available. The usual starting point for cli ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Skythes
Skythes ( el, Σκύθης, ''the Scythian'') was an Attic black-figureAcropolis Museum Guide (Athens 2015) , p. 168. and red-figure vase painter active between about 520 and 505 BC. Modern scholarship considers Skythes as a kind of artistic loner, whose work cannot easily be categorised among the known workshops and groups. He signed four known '' kylikes''. Further, another ''ca''. twenty ''kylikes'' and two ''dinos'' stands are attributed to him on the basis of stylistic analysis. His early works were created a short time after the invention of the red-figure technique. On three bilingual works he demonstrates his skill in the older black-figure style. Unusually, they feature red-figure paintings on the interior and on the outside black-figure on coral-red ground. Inside and outside each bear only one figure. He belonged to the first generation of vase painters to specialise in cups. His figural images depict people in an exaggerated ugliness or brutishness, casting him, much i ...

Eurasian Steppe
The Eurasian Steppe, also simply called the Great Steppe or the steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Hungary, Bulgaria, Romania, Moldova and Transnistria, Ukraine, Western Russia, Siberia, Kazakhstan, Xinjiang, Mongolia and Manchuria, with one major exclave, the Pannonian steppe or Puszta, located mostly in Hungary. Since the Paleolithic age, the Steppe Route has connected Central Europe, Eastern Europe, Western Asia, Central Asia, East Asia and South Asia economically, politically and culturally through overland trade routes. The Steppe route is a predecessor not only of the Silk Road which developed during antiquity and the Middle Ages, but also of the Eurasian Land Bridge in the modern era. It has been home to nomadic empires and many large tribal confederations and ancient states throughout history, such as the Xiongnu, Scythia, Cimmeria, Sarmatia, Hunnic Empire, Chorasmia, Tr ...
