Royal Road (Kraków)
The Royal Road was an ancient highway reorganized and rebuilt for trade in the 5th century BC Achaemenid Empire. The road was built to facilitate rapid communication on the western part of the large empire from Susa to Sardis and was probably perfected under Darius I. Mounted couriers of the Angarium were supposed to travel from Susa to Sardis in nine days; the journey took ninety days on foot. Course The course of the road has been reconstructed from the writings of Herodotus, archeological research, and other historical records. History Because the road did not follow the shortest nor the easiest route between the most important cities of the empire, archeologists believe the westernmost sections of the road may have originally been built by the Assyrian kings, as the road plunges through the heart of their old empire. More eastern segments of the road, identifiable in present-day northern Iran, were not noted by Herodotus, whose view of Persia was that of an Ionian Greek in ...

Achaemenid Empire At Its Greatest Extent According To Oxford Atlas Of World History 2002
The Achaemenid Empire or Achaemenian Empire, also known as the Persian Empire or First Persian Empire (; , , ), was an Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. Based in modern-day Iran, it was the largest empire by that point in history, spanning a total of . The empire spanned from the Balkans and Egypt in the west, most of West Asia, the majority of Central Asia to the northeast, and the Indus Valley of South Asia to the southeast. Around the 7th century BC, the region of Persis in the southwestern portion of the Iranian plateau was settled by the Persians. From Persis, Cyrus rose and defeated the Median Empire as well as Lydia and the Neo-Babylonian Empire, marking the establishment of a new imperial polity under the Achaemenid dynasty. In the modern era, the Achaemenid Empire has been recognised for its imposition of a successful model of centralised bureaucratic administration, its multicultural policy, building complex infrastructu ...

Gordion
Gordion (Phrygian language, Phrygian: ; ; or ; ) was the capital city of ancient Phrygia. It was located at the site of modern Yassıhüyük, Polatlı, Yassıhüyük, about southwest of Ankara (capital of Turkey), in the immediate vicinity of Polatlı district. Gordion's location at the confluence of the Sakarya River, Sakarya and Porsuk River, Porsuk rivers gave it a strategic location with control over fertile land. Gordion lies where the ancient road between Lydia and Assyria/Babylonia crossed the Sakarya River, Sangarius river. Occupation at the site is attested from the Early Bronze Age () continuously until the 4th century CE and again in the 13th and 14th centuries CE. The Citadel Mound at Gordion is approximately 13.5 hectares in size, and at its height habitation extended beyond this in an area approximately 100 hectares in size. Gordion is the type site of Phrygians, Phrygian civilization, and its well-preserved destruction level of is a chronological linchpin in the ...

Alexander The Great
Alexander III of Macedon (; 20/21 July 356 BC – 10/11 June 323 BC), most commonly known as Alexander the Great, was a king of the Ancient Greece, ancient Greek kingdom of Macedonia (ancient kingdom), Macedon. He succeeded his father Philip II of Macedon, Philip II to the throne in 336 BC at the age of 20 and spent most of his ruling years conducting Wars of Alexander the Great, a lengthy military campaign throughout West Asia, Western Asia, Central Asia, parts of South Asia, and ancient Egypt, Egypt.

Menaechmus
Menaechmus (, c. 380 – c. 320 BC) was an ancient Greek mathematician, list of geometers, geometer and philosopher born in Alopeconnesus or Prokonnesos in the Thracian Chersonese, who was known for his friendship with the renowned philosopher Plato and for his apparent discovery of conic sections and his solution to the then-long-standing problem of doubling the cube using the parabola and hyperbola. Life and work Menaechmus is remembered by mathematicians for his discovery of the conic sections and his solution to the problem of doubling the cube. Menaechmus likely discovered the conic sections, that is, the ellipse, the parabola, and the hyperbola, as a by-product of his search for the solution to the Delian problem. Menaechmus knew that in a parabola y2 = ''L''x, where ''L'' is a constant called the ''latus rectum'', although he was not aware of the fact that any equation in two unknowns determines a curve. He apparently derived these properties of conic sections and others ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proclus
Proclus Lycius (; 8 February 412 – 17 April 485), called Proclus the Successor (, ''Próklos ho Diádokhos''), was a Greek Neoplatonist philosopher, one of the last major classical philosophers of late antiquity. He set forth one of the most elaborate and fully developed systems of Neoplatonism and, through later interpreters and translators, exerted an influence on Byzantine philosophy, early Islamic philosophy, scholastic philosophy, and German idealism, especially G. W. F. Hegel, who called Proclus's ''Platonic Theology'' "the true turning point or transition from ancient to modern times, from ancient philosophy to Christianity." Biography The primary source for the life of Proclus is the eulogy ''Proclus'', ''or On Happiness'' that was written for him upon his death by his successor, Marinus, Marinus' biography set out to prove that Proclus reached the peak of virtue and attained eudaimonia. There are also a few details about the time in which he lived in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptolemy I
Ptolemy I Soter (; , ''Ptolemaîos Sōtḗr'', "Ptolemy the Savior"; 367 BC – January 282 BC) was a Macedonian Greek general, historian, and successor of Alexander the Great who went on to found the Ptolemaic Kingdom centered on Egypt. Ptolemy was ''basileus'' and pharaoh of Ptolemaic Egypt from 305/304 BC to his death in 282 BC, and his descendants continued to rule Egypt until 30 BC. During their rule, Egypt became a thriving bastion of Hellenistic civilization and Alexandria a great seat of Greek culture. Ptolemy I was the son of Arsinoe of Macedon by either her husband Lagus or Philip II of Macedon, the father of Alexander. However, the latter is unlikely and may be a myth fabricated to glorify the Ptolemaic Dynasty. Ptolemy was one of Alexander's most trusted companions and military officers. After the death of Alexander in 323 BC, Ptolemy retrieved his body as it was en route to be buried in Macedon, placing it in Memphis instead, where it was later moved to A ...

Euclid
Euclid (; ; BC) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the '' Elements'' treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics. Very little is known of Euclid's life, and most information comes from the scholars Proclus and Pappus of Alexandria many centuries later. Medieval Islamic mathematicians invented a fanciful biography, and medieval Byzantine and early Renaissance scholars mistook him for the earlier philo ...

United States Postal Service Creed
"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds" is a phrase long associated with the American postal worker. Though not an official creed or motto of the United States Postal Service, * * the Postal Service does acknowledge it as an informal motto along with a slightly revised version of Charles W. Eliot's poem "The Letter". The phrase's association with the U.S. Mail originated with its inscription on New York City's James A. Farley Post Office Building, which opened in 1914. The inscription was added to the building by William M. Kendall of the architectural firm of McKim, Mead & White, the building's architects. The phrase derives from a passage in George Herbert Palmer's translation of Herodotus's '' Histories'', referring to the courier service of the ancient Persian Empire: This slogan is not a formal commitment, and in fact the USPS may delay mail during bad weather. __NOTOC__ Referen ...

James Farley Post Office
The James A. Farley Building (formerly Pennsylvania Terminal and the U.S. General Post Office) is a mixed-use structure in Midtown Manhattan, New York City, which formerly served as the city's main United States Postal Service (USPS) branch. Designed by McKim, Mead & White in the Beaux-Arts style, the structure was built between 1911 and 1914, with an annex constructed between 1932 and 1935. The Farley Building, at 421 Eighth Avenue between 31st Street and 33rd Street in Midtown Manhattan, faces Pennsylvania Station and Madison Square Garden to the east. The main facade of the Farley Building (over 8th Avenue) features a Corinthian colonnade finishing at a pavilion on each end. The imposing design was meant to match that of the original Pennsylvania Station across the street. An entablature above the colonnade bears the United States Postal Service creed: "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rou ...

Ancient Greece
Ancient Greece () was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War.

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus An abacus ( abaci or abacuses), also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoptio ...
