Information:  - Megara is a historic town and a municipality in West Attica, Greece. It lies in the northern section of the Isthmus of Corinth opposite the island of Salamis, which belonged to Megara in archaic times, before being taken by Athens. Megara was one of the four districts of Attica, embodied in the four mythic sons of King Pandion II, of whom Nisos was the ruler of Megara. Megara was also a trade port, its people using their ships and wealth as a way to gain leverage on armies of neighboring poleis. Megara specialized in the exportation of wool and other animal products including livestock such as horses. It possessed two harbors, Pegae, to the west on the Corinthian Gulf and Nisaea, to the east on the Saronic Gulf of the Aegean Sea.  - Thucydides ("Thoukudíds", ; c. 460  c. 400 BC) was an Athenian historian and general. His "History of the Peloponnesian War" recounts the 5th century BC war between Sparta and Athens to the year 411 BC. Thucydides has been dubbed the father of "scientific history" because of his strict standards of evidence-gathering and analysis of cause and effect without reference to intervention by the gods, as outlined in his introduction to his work.  - Acanthus the Lacedaemonian ( Ancient Greek :  ) , was the victor in two footrace events , the diaulos (  ) and dolichos (  ) , in the Olympic Games of 720 BC. He was also , according to some accounts , the first who ran naked in these games . Other accounts ascribe this to Orsippus the Megarian . Thucydides says that the Lacedaemonians were indeed the first who contended naked in gymnastic games , although he does not mention Acanthus by name .  - Orsippus was a Greek runner from Megara who was famed as the first to run the footrace naked at the Olympic Games and "first of all Greeks to be crowned victor naked." Others argue that it was Acanthus instead who first introduced Greek athletic nudity. Orsippus won the stadion-race of the 15th Olympic Games in 720 BC.  - Sparta (Doric Greek: ; Attic Greek: ) was a prominent city-state in ancient Greece. In antiquity the city-state was known as Lacedaemon, while the name Sparta referred to its main settlement on the banks of the Eurotas River in Laconia, in south-eastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece.  - The History of the Peloponnesian War (Greek: "") is a historical account of the Peloponnesian War (431404 BC), which was fought between the Peloponnesian League (led by Sparta) and the Delian League (led by Athens). It was written by Thucydides, an Athenian historian who also happened to serve as an Athenian general during the war. His account of the conflict is widely considered to be a classic and regarded as one of the earliest scholarly works of history. The "History" is divided into eight books.  - A historian is a person who researches, studies, and writes about the past, and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. If the individual is concerned with events preceding written history, the individual is a historian of prehistory. Although "historian" can be used to describe amateur and professional historians alike, it is reserved more recently for those who have acquired graduate degrees in the discipline. Some historians, though, are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere.  - Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates 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 starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, 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 impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study.
