Diacria
Diacria (Διακρία) is an ancient name for the highlands in the north-east of Attica in Greece, surrounding the Plain of Marathon. Attica may be divided into five natural parts: * The Eleusinian Plain * The Athenian Plain * The Paralia or Sea-coasts * The Mesogaea or Midlands * The Diacria or Highlands North-east of the Athenian plain, between Parnes, Pentelicus, and the sea, is a mountain district, known by the name of Diacria (Διακρία) in antiquity. Its inhabitants, usually called Diacreis or Diacrii (Διακρεῖς, ''Diakreis'' or Διακρίοι, ''Diakrioi''), were sometimes also termed Hyperacrii (Ὑπερακρίοι. ''Hyperakrioi''), apparently from their dwelling on the other side of the mountain from the city. The only level part of this district is the small plain of Marathon, open to the sea. When the astronomer E. M. Antoniadi created his 1930 encyclopedic study of Mars, ''La Planète Mars'', he named a small greyish region in the planet's northe ...

Diacria Quadrangle
The Diacria quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the northwestern portion of Mars’ western hemisphere and covers 180° to 240° east longitude (120° to 180° west longitude) and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Diacria quadrangle is also referred to as MC-2 (Mars Chart-2). The Diacria quadrangle covers parts of Arcadia Planitia and Amazonis Planitia. The southern and northern borders of the Diacria quadrangle are approximately and wide, respectively. The north to south distance is about (slightly less than the length of Greenland). The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars’ surface area. The ''Phoenix'' lander’s landing site (68.22° N, 234.25° E) lies about 186 km north of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Quadrangles On Mars
The surface of Mars has been divided into thirty cartographic quadrangles by the United States Geological Survey. Each quadrangle is a region covering a specified range of latitudes and longitudes on the Martian surface. The quadrangles are named after classical albedo features, and they are numbered from one to thirty with the prefix "MC" (for "Mars Chart"), with the numbering running from north to south and from west to east. The quadrangles appear as rectangles on maps based on a cylindrical map projection, but their actual shapes on the curved surface of Mars are more complicated Saccheri quadrilaterals. The sixteen equatorial quadrangles are the smallest, with surface areas of each, while the twelve mid-latitude quadrangles each cover . The two polar quadrangles are the largest, with surface areas of each. History In 1972, NASA's Mariner 9 mission returned thousands of photographs collectively covering more than 80% of the Martian surface. That year and the next, NASA' ...

Attica
Attica ( el, Αττική, Ancient Greek ''Attikḗ'' or , or ), or the Attic Peninsula, is a historical region that encompasses the city of Athens, the capital of Greece and its countryside. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The southern tip of the peninsula, known as Laurion, was an important mining region. The history of Attica is tightly linked with that of Athens, and specifically the Golden Age of Athens during the classical period. Ancient Attica ( Athens city-state) was divided into demoi or municipalities from the reform of Cleisthenes in 508/7 BC, grouped into three zones: urban (''astu'') in the region of Athens main city and Piraeus (port of Athens), coastal (''paralia'') along the coastline and inland ('' mesogeia'') in the interior. The modern administrative region of Attica is more extensive than the historical region and includes Megaris as part of the regional unit West Att ...

Marathon, Greece
Marathon (Demotic Greek: Μαραθώνας, ''Marathónas''; Attic/Katharevousa: , ''Marathṓn'') is a town in Greece and the site of the Battle of Marathon in 490 BCE, in which the heavily outnumbered Athenian army defeated the Persians. Legend has it that Pheidippides, a Greek herald at the battle, was sent running from Marathon to Athens to announce the victory, which is how the marathon running race was conceived in modern times. Today it is part of East Attica regional unit, in the outskirts of Athens and a popular resort town and center of agriculture. History The name "Marathon" () comes from the herb fennel, called ''marathon'' () or ''marathos'' () in Ancient Greek,. so ''Marathon'' literally means "a place full of fennel".. It is believed that the town was originally named so because of an abundance of fennel plants in the area. In ancient times, Marathon ( grc, Μαραθών) occupied a small plain in the northeast of ancient Attica, which contained four place ...

Eleusinian Plain
The Thriasio Plain ( el, Θριάσιο Πεδίο, translit=Thriasio Pedio) is a plain in western Attica, immediately to the west of Athens, in Greece. It is bounded by Mount Egaleo to the east, Mount Parnitha to the north, Mount Pateras to the west, and the Bay of Elefsina to the south. History The Thriasio Plain owes its name to the ancient deme of Thria ( el, Θρία), one the demes of ancient Athens. The largest town in the plain was Eleusis (modern-day Elefsina), location of the famous Eleusinian Mysteries. In Greek mythology, when the goddess Athena won the contest for control of Attica over Poseidon, Poseidon flooded the plain in wrath, until called to order by Zeus. In antiquity, as today, the area was connected to central Athens by two passes: the Sacred Way ( el, Ιερά Οδός) to the west, today used by the main Athens–Corinth highway, and another pass to the northwest nowadays used by the Attiki Odos highway. During the Peloponnesian War (431–40 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athenian Plain
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In ...

Paralia (Attica)
The Paralia ( el, Παραλία, 3=the sea-side/coast) was a geographical and administrative region (''trittys'') of ancient Attica. The term designated the coasts of Attica, but was also generally used for the entire portion of Attica east of Mount Hymettus. The term acquired a technical meaning with the reforms of Cleisthenes in , when each of the ten Attic tribes was made to territory from comprise three zones (''trittyes''), urban (''asty'', the city of Athens), interior (''mesogeia'') and coastal (''paralia''). In the Classical period, the ''paralia'' comprised about 40 settlements (''demoi In Ancient Greece, a deme or ( grc, δῆμος, plural: demoi, δημοι) was a suburb or a subdivision of Athens and other city-states.

Mesogaea
The Mesogeia or Mesogaia ( el, τα Μεσόγεια, η Μεσόγαια/Μεσογαία, "Midlands") is a geographical region of Attica in Greece. History The term designates since antiquity the inland portion of the Attic peninsula. The term acquired a technical meaning with the reforms of Cleisthenes in , when each of the ten Attic tribes was in territory composed of three zones ('' trittyes''), urban ('' asty'', the main city of Athens), interior (''mesogeia'') and coastal (''paralia''). In the Classical period, the ''mesogeia'' comprised about 47 settlements ('' demoi''). In modern usage, the term refers to the central portion of East Attica, separated from the Athens basin by Mount Hymettus, and delineated to the north by Mount Penteli and to the south by the mountains of south Attica (Merenta, , Laureotic Olympus). To the east the Mesogeia reaches the Aegean Sea at the Petalioi Gulf, but is separated from the actual coastline by a line of low hills. In the late Midd ...
