Strait Of Euripus
The Euripus Strait ( ) is a narrow channel of water separating the Greek island of Euboea in the Aegean Sea from Boeotia in mainland Greece. The strait's principal port is Chalcis on Euboea, located at the strait's narrowest point. The strait is subject to strong tidal currents which reverse direction approximately four times a day. Tidal flows are very weak in the Eastern Mediterranean, but the strait is a remarkable exception. Water flow peaks at about , either northwards or southwards, and lesser vessels are often incapable of sailing against it. When nearing flow reversal, sailing is even more precarious because of vortex formation. The Swiss scholar François-Alphonse Forel contributed to an understanding of the enigmatic phenomenon by his study of limnology and the discovery of seiche, where layers of water of differing temperature oscillate in thickness in a confined body of water. But the problem was solved completely only by D. Eginitis, director of the Athens Observat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euboea Island
Euboea ( ; , ), also known by its modern spelling Evia ( ; , ), is the second-largest List of islands of Greece, Greek island in area and population, after Crete, and the List of islands in the Mediterranean#By area, sixth largest island in the Mediterranean Sea. It is separated from Boeotia in mainland Greece by the narrow Euripus Strait (only at its narrowest point). In general outline it is a long and narrow island; it is about long, and varies in breadth from to . Its geographic orientation is from northwest to southeast, and it is traversed throughout its length by a mountain range, which forms part of the chain that bounds Thessaly on the east, and is continued south of Euboia in the lofty islands of Andros, Tinos and Mykonos. It forms most of the Euboea (regional unit), regional unit of Euboea, which also includes Skyros and a small area of the Greek mainland. Name Like most of the Greek islands, Euboea was known by other names in Ancient Greece, antiquity, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliotheca Historica
''Bibliotheca historica'' (, ) is a work of Universal history (genre), universal history by Diodorus Siculus. It consisted of forty books, which were divided into three sections. The first six books are geographical in theme, and describe the history and culture of Egypt (book I), of Mesopotamia, India, Scythia, and Arabia (II), of North Africa (III), and of Greece and Europe (IV–VI). In the next section (books VII–XVII), he recounts human history starting with the Trojan War, down to the death of Alexander the Great. The last section (books XVII to the end) concern the historical events from the Diadochi, successors of Alexander down to either 60 BC or the beginning of Julius Caesar, Caesar's Gallic War in 59 BC. (The end has been lost, so it is unclear whether Diodorus reached the beginning of the Gallic War, as he promised at the beginning of his work, or, as evidence suggests, old and tired from his labors he stopped short at 60 BC.) He selected the name "Bibliotheca" in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diodorus Siculus
Diodorus Siculus or Diodorus of Sicily (; 1st century BC) was an ancient Greece, ancient Greek historian from Sicily. He is known for writing the monumental Universal history (genre), universal history ''Bibliotheca historica'', in forty books, fifteen of which survive intact, between 60 and 30 BC. The history is arranged in three parts. The first covers mythic history up to the destruction of Troy, arranged geographically, describing regions around the world from Egypt, India and Arabia to Europe. The second covers the time from the Trojan War to the death of Alexander the Great. The third covers the period to about 60 BC. ''Bibliotheca'', meaning 'library', acknowledges that he was drawing on the work of many other authors. Life According to his own work, he was born in Agira, Agyrium in Sicily (now called Agira). With one exception, classical antiquity, antiquity affords no further information about his life and doings beyond his written works. Only Jerome, in his ''Ch ...

Trireme
A trireme ( ; ; cf. ) was an ancient navies and vessels, ancient vessel and a type of galley that was used by the ancient maritime civilizations of the Mediterranean Sea, especially the Phoenicians, ancient Greece, ancient Greeks and ancient Rome, Romans. The trireme derives its name from its three rows of oars, manned with one man per oar. The early trireme was a development of the penteconter (ship), penteconter, an ancient warship with a single row of 25 oars on each side (i.e., a single-banked boat), and of the bireme (, ), a warship with two banks of oars, of Phoenician origin. The word ''dieres'' does not appear until the Roman period. According to Morrison and Williams, "It must be assumed the term pentekontor covered the two-level type". As a ship, it was fast and agile and was the dominant warship in the Mediterranean from the 7th to the 4th centuries BC, after which it was largely superseded by the larger quadriremes and quinqueremes. Triremes played a vital role in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Artemisium
The Battle of Artemisium or Artemision was a series of naval engagements over three days during the second Persian invasion of Greece. The battle took place simultaneously with the land battle at Thermopylae, in August or September 480 BC, off the coast of Euboea and was fought between an alliance of Greek city-states, including Sparta, Athens, Corinth and others, and the Persian Empire of Xerxes I. The Persian invasion was a delayed response to the defeat of the first Persian invasion of Greece, which had been ended by the Athenian victory at the Battle of Marathon. King Xerxes had amassed a huge army and navy, and set out to conquer all of Greece. The Athenian general Themistocles proposed that the Allied Greeks block the advance of the Persian army at the pass of Thermopylae and simultaneously block the Persian navy at the Straits of Artemisium. An Allied naval force of 271 triremes was thus dispatched to await the arrival of the Persians. Approaching Artemisium towa ...

Herodotus
Herodotus (; BC) was a Greek historian and geographer from the Greek city of Halicarnassus (now Bodrum, Turkey), under Persian control in the 5th century BC, and a later citizen of Thurii in modern Calabria, Italy. He wrote the '' Histories'', a detailed account of the Greco-Persian Wars, among other subjects such as the rise of the Achaemenid dynasty of Cyrus. He has been described as " The Father of History", a title conferred on him by the ancient Roman orator Cicero, and the " Father of Lies" by others. The ''Histories'' primarily cover the lives of prominent kings and famous battles such as Marathon, Thermopylae, Artemisium, Salamis, Plataea, and Mycale. His work deviates from the main topics to provide a cultural, ethnographical, geographical, and historiographical background that forms an essential part of the narrative and provides readers with a wellspring of additional information. Herodotus was criticized in his times for his inclusion of "legends an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dike (geology)
In geology, a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reaches the surface. They are studied by geologists for the clues they ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or one-eighth turn, in order to clear the channel. Small swing bridges as found over narrow canals may be pivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retractable Bridge
A retractable bridge is a type of moveable bridge in which the deck can be rolled or slid backwards to open a gap while traffic crosses, usually a ship on a waterway. This type is sometimes referred to as a thrust bridge. Retractable bridges date back to medieval times. Due to the large dedicated area required for this type of bridge, this design is not common. A retractable design may be considered when the maximum horizontal clearance is required (for example, over a canal). Two remaining examples exist in New York City: the Carroll Street Bridge (built 1889) in Brooklyn, and the Borden Avenue Bridge in Queens. A recent example can be found at Queen Alexandra Dock in Cardiff, Wales, where the bridge is jacked upwards before being rolled on wheels. Helix Bridge at Paddington Basin in London is a more unusual example of the type, consisting of a glass shell supported in a helical steel frame, which rotates as it retracts. The Summer Street Bridge over Fort Point Channel i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avlida
Avlida (, ) or Aulis () a former municipality in Euboea regional unit, Greece. Since the 2011 local government reform it is part of the municipality Chalcis, of which it is a municipal unit. The population was 10,006 inhabitants at the 2021 census, and the land area is 122.235 km2. The seat of the municipality was in Vathy. Although part of the Euboea regional unit, it is not located on the island Euboea, but on the mainland, attached to the northeastern part of Boeotia. Traditionally, it is identified with the ancient Aulis, the port from which the Greek army set sail for the Trojan War and the setting for the Euripides play, '' Iphigenia in Aulis''. History It is unknown when exactly Avlida was founded. The region was settled in Antiquity, but the modern settlement likely dates to the early 11th century, when the local church of Saint Nicholas was built. Additional Byzantine-era remains have been found near the location of the ancient temple of Artemis. In 1350, as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euripus Bridge
Euripus Bridge (also ''Euripos Bridge'', ''Evripos Bridge''; ) is a cable-stayed bridge located in Chalcis that crosses the Euripus Strait, the central and narrowest part of the channel separating the island of Euboea Euboea ( ; , ), also known by its modern spelling Evia ( ; , ), is the second-largest Greek island in area and population, after Crete, and the sixth largest island in the Mediterranean Sea. It is separated from Boeotia in mainland Greece by ... from the Greek mainland. Built in 1992, the bridge was the first cable-stayed road bridge in Greece. A technical challenge during the design and the construction phase was the extremely slender (L/480) longitudinally and transversally pre-stressed concrete deck with only constant thickness, providing sufficient stiffness to omit longitudinal girders. The multi-strand stay-cables therefore have a closer spacing of approximately with a minimum inclination of 23 degrees (0.4 rad) and were directly used to support the fr ...
