Hero of AlexandriaHero of Alexandria (ˈhɪəroʊ; Ἥρων ὁ Ἀλεξανδρεύς, Hērōn hò Alexandreús, also known as Heron of Alexandria ˈhɛrən; 60 AD) was a Greek mathematician and engineer who was active in his native city of Alexandria in Egypt during the Roman era. He is often considered the greatest experimenter of antiquity and his work is representative of the Hellenistic scientific tradition. Hero published a well-recognized description of a steam-powered device called an aeolipile (sometimes called a "Hero engine").
AstrolabeAn astrolabe (ἀστρολάβος astrolábos; ٱلأَسْطُرلاب al-Asṭurlāb; ستارهیاب Setāreyāb) is an astronomical instrument dating back to ancient times. It serves as a star chart and physical model of visible heavenly bodies. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely.
BoeotiaBoeotia (biˈoʊʃ(i)ə ), sometimes Latinized as Boiotia or Beotia (Βοιωτία; modern: ; ancient: ) is one of the regional units of Greece. It is part of the region of Central Greece. Its capital is Livadeia, and its largest city is Thebes. Boeotia was also a region of ancient Greece, from before the 6th century BC. Boeotia lies to the north of the eastern part of the Gulf of Corinth. It also has a short coastline on the Gulf of Euboea.
KnidosKnidos or Cnidus (ˈnaɪdəs; Κνίδος, knídos, ˈkniðos, Knídos) was a Greek city in ancient Caria and part of the Dorian Hexapolis, in south-western Asia Minor, modern-day Turkey. It was situated on the Datça peninsula, which forms the southern side of the Sinus Ceramicus, now known as Gulf of Gökova. By the 4th century BC, Knidos was located at the site of modern Tekir, opposite Triopion Island. But earlier, it was probably at the site of modern Datça (at the half-way point of the peninsula).
PraxitelesPraxiteles (prækˈsɪtᵻliːz; Πραξιτέλης) of Athens, the son of Cephisodotus the Elder, was the most renowned of the Attica sculptors of the 4th century BC. He was the first to sculpt the nude female form in a life-size statue. While no indubitably attributable sculpture by Praxiteles is extant, numerous copies of his works have survived; several authors, including Pliny the Elder, wrote of his works; and coins engraved with silhouettes of his various famous statuary types from the period still exist.
DoriansThe Dorians (ˈdɔriənz; Δωριεῖς, Dōrieîs, singular Δωριεύς, Dōrieús) were one of the four major ethnic groups into which the Hellenes (or Greeks) of Classical Greece divided themselves (along with the Aeolians, Achaeans, and Ionians). They are almost always referred to as just "the Dorians", as they are called in the earliest literary mention of them in the Odyssey, where they already can be found inhabiting the island of Crete.
Battle of LeuctraThe Battle of Leuctra (Λεῦκτρα, lêu̯k.tra) was a battle fought on 6 July 371 BC between the Boeotians led by the Thebans, and the Spartans along with their allies amidst the post–Corinthian War conflict. The battle took place in the vicinity of Leuctra, a village in Boeotia in the territory of Thespiae. The Theban victory shattered Sparta's immense influence over the Greek peninsula, which Sparta had gained with its victory in the Peloponnesian War a generation earlier.
TycheTyche (ˈtaɪki; Ancient Greek: Τύχη Túkhē, 'Luck', tý.khɛː, ˈti.çi; Roman equivalent: Fortuna) was the presiding tutelary deity who governed the fortune and prosperity of a city, its destiny. In Classical Greek mythology, she is usually the daughter of the Titans Tethys and Oceanus, or sometimes Zeus, and at this time served to bring positive messages to people, relating to external events outside their control.
Antikythera mechanismThe Antikythera mechanism (ˌæntɪˈkɪθɪərə ) is an Ancient Greek hand-powered orrery, described as the oldest known example of an analogue computer used to predict astronomical positions and eclipses decades in advance. It could also be used to track the four-year cycle of athletic games which was similar to an Olympiad, the cycle of the ancient Olympic Games. This artefact was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera in 1901.
CallimachusCallimachus (Καλλίμαχος; 310 240 BC) was an ancient Greek poet, scholar and librarian who was active in Alexandria during the 3rd century BC. A representative of Ancient Greek literature of the Hellenistic period, he wrote over 800 literary works in a wide variety of genres, most of which did not survive. He espoused an aesthetic philosophy, known as Callimacheanism, which exerted a strong influence on the poets of the Roman Empire and, through them, on all subsequent Western literature.
