Callicrates
Callicrates or Kallikrates (; el, Καλλικράτης ) was an ancient Greek architect active in the middle of the fifth century BC. He and Ictinus were architects of the Parthenon (Plutarch, ''Pericles'', 13). An inscription identifies him as the architect of "the Temple of Nike" on the Acropolis of Athens (IG I3 35). The temple in question is either the amphiprostyle Temple of Athena Nike now visible on the site or a small-scale predecessor (naiskos) whose remains were found in the later temple's foundations. An inscription identifies Callicrates as one of the architects of the Classical circuit wall of the Acropolis (IG I3 45), and Plutarch further states (loc. cit.) that he was contracted to build the Middle of three amazing walls linking Athens and Piraeus. A crater on the planet Mercury was named in his honor. References Sources *Plutarch Plutarch (; grc-gre, Πλούταρχος, ''Ploútarchos''; ; – after AD 119) was a Greek Middle Platonist phil ...

Parthenon
The Parthenon (; grc, Παρθενών, , ; ell, Παρθενώνας, , ) is a former temple on the Athenian Acropolis, Greece, that was dedicated to the goddess Athena during the fifth century BC. Its decorative sculptures are considered some of the high points of Greek art, an enduring symbol of Ancient Greece, democracy and Western civilization. The Parthenon was built in thanksgiving for the Hellenic victory over Persian invaders during the Greco-Persian Wars. Like most Greek temples, the Parthenon also served as the city treasury. Construction started in 447 BC when the Delian League was at the peak of its power. It was completed in 438; work on the decoration continued until 432. For a time, it served as the treasury of the Delian League, which later became the Athenian Empire. In the final decade of the 6th century AD, the Parthenon was converted into a Christian church dedicated to the Virgin Mary. After the Ottoman conquest in the mid-fifteenth century ...

Acropolis Of Athens
The Acropolis of Athens is an ancient citadel located on a rocky outcrop above the city of Athens and contains the remains of several ancient buildings of great architectural and historical significance, the most famous being the Parthenon. The word '' acropolis'' is from the Greek words (''akron'', "highest point, extremity") and (''polis'', "city"). The term acropolis is generic and there are many other acropoleis in Greece. During ancient times the Acropolis of Athens was known also more properly as Cecropia, after the legendary serpent-man, Cecrops, the supposed first Athenian king. While there is evidence that the hill was inhabited as far back as the fourth millennium BC, it was Pericles (c. 495–429 BC) in the fifth century BC who coordinated the construction of the buildings whose present remains are the site's most important ones, including the Parthenon, the Propylaea, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were serio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ictinus
Ictinus (; el, Ἰκτῖνος, ''Iktinos'') was an architect active in the mid 5th century BC. Ancient sources identify Ictinus and Callicrates as co-architects of the Parthenon. He co-wrote a book on the project – which is now lost – in collaboration with Carpion. Pausanias (geographer), Pausanias identifies Ictinus as architect of the Temple of Apollo at Bassae. That temple was Doric order, Doric on the exterior, Ionic order, Ionic on the interior, and incorporated a Corinthian order, Corinthian column, the earliest known, at the center rear of the cella. Sources also identify Ictinus as architect of the Telesterion at Eleusis, a gigantic hall used in the Eleusinian Mysteries. Pericles also commissioned Ictinus to design the Telesterion (Hall of mystery ) at Eleusis, but his involvement was terminated when Pericles fell from power. Three other architects took over instead. It seems likely that Ictinus's reputation was harmed by his links with the fallen ruler, as he is sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, 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 G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5th-century BC Athenians
The 5th century is the time period from 401 ( CDI) through 500 ( D) ''Anno Domini'' (AD) or Common Era (CE) in the Julian calendar. The 5th century is noted for being a period of migration and political instability throughout Eurasia. It saw the collapse of the Western Roman Empire, which came to an end in 476 AD. This empire had been ruled by a succession of weak emperors, with the real political might being increasingly concentrated among military leaders. Internal instability allowed a Visigoth army to reach and ransack Rome in 410. Some recovery took place during the following decades, but the Western Empire received another serious blow when a second foreign group, the Vandals, occupied Carthage, capital of an extremely important province in Africa. Attempts to retake the province were interrupted by the invasion of the Huns under Attila. After Attila's defeat, both Eastern and Western empires joined forces for a final assault on Vandal North Africa, but this campaign was ...

Ancient Greek Architects
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages varies between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was already exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world population stood at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Walls
Although long walls were built at several locations in ancient Greece, notably Corinth and Megara, the term Long Walls ( grc, Μακρὰ Τείχη ) generally refers to the walls that connected Athens main city to its ports at Piraeus and Phaleron. Built in several phases, they provided a secure connection to the sea even during times of siege. The walls were about 6 km in length. They were initially constructed in the mid 5th century BC, and destroyed by the Spartans in 403 BC after Athens' defeat in the Peloponnesian War. They were rebuilt with Persian support during the Corinthian War in 395–391 BC. The Long Walls were a key element of Athenian military strategy, since they provided the city with a constant link to the sea and thwarted sieges conducted by land alone. History Background The ancient wall around the Acropolis was destroyed by the Persians during the occupations of Attica in 480 and 479 BC, part of the Greco-Persian Wars. After the Battle of Pla ...
