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 defensive walls linking Athens and Piraeus. A crater on the planet Mercury was named in his honor.

Ictinus
Ictinus (; , ''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 identifies Ictinus as architect of the Temple of Apollo at Bassae. That temple was Doric on the exterior, Ionic on the interior, and incorporated a 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 Final Things") at Eleusis, but his involvement was terminated when Pericles fell from power.

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.

5th-century BC Athenians
The 5th century is the time period from AD 401 (represented by the Roman numerals CDI) through AD 500 (D) in accordance with 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 a formal 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500, ending with the Early Muslim conquests, expansion of Islam in late antiquity. The three-age system periodises 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 vary 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.

Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere.

The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star".

Long Walls
Although long walls were built at several locations in ancient Greece, notably Corinth and Megara, the term ''Long Walls'' ( ) generally refers to the walls that connected classical Athens, Athens' main city to its ports at Piraeus and Phalerum, Phaleron. Built in several phases, they provided a secure connection to the sea even during times of siege. The walls were about 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.
