DemosthenesDemosthenes (dɪˈmɒs.θəniːz; Δημοσθένης; dɛːmosˈthenɛːs; 384 – 12 October 322 BC) was a Greek statesman and orator in ancient Athens. His orations constitute a significant expression of contemporary Athenian intellectual prowess and provide insight into the politics and culture of ancient Greece during the 4th century BC. Demosthenes learned rhetoric by studying the speeches of previous great orators. He delivered his first judicial speeches at the age of 20, in which he successfully argued that he should gain from his guardians what was left of his inheritance.
PergamonPergamon or Pergamum (ˈpɜrɡəmən or ˈpɜrɡəmɒn; Πέργαμον), also referred to by its modern Greek form Pergamos (Πέργαμος), was a rich and powerful ancient Greek city in Mysia. It is located from the modern coastline of the Aegean Sea on a promontory on the north side of the river Caicus (modern-day Bakırçay) and northwest of the modern city of Bergama, Turkey. During the Hellenistic period, it became the capital of the Kingdom of Pergamon in 281–133 BC under the Attalid dynasty, who transformed it into one of the major cultural centres of the Greek world.
Caesar's civil warCaesar's civil war (49–45 BC) was a civil war during the late Roman Republic between Gaius Julius Caesar and Gnaeus Pompeius Magnus. The main cause of the war was political tensions relating to Caesar's place in the republic on his expected return to Rome on the expiration of his governorship in Gaul. Before the war, Caesar had led an invasion of Gaul for almost ten years. A build-up of tensions starting in late 50 BC, with both Caesar and Pompey refusing to back down, led to the outbreak of civil war.
Abbasid CaliphateThe Abbasid Caliphate was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH).
Ptolemaic dynastyThe Ptolemaic dynasty (ˌtɒlɪˈmeɪ.ɪk; Πτολεμαῖοι, Ptolemaioi), also House of Ptolemy, or Lagid dynasty (Λαγίδαι, Lagidae; after Ptolemy I's father, Lagus), was a Macedonian Greek royal dynasty which ruled the Ptolemaic Kingdom in Ancient Egypt during the Hellenistic period. Their rule lasted for 275 years, from 305 to 30 BC. The Ptolemaic was the last dynasty of ancient Egypt. Ptolemy, one of the seven somatophylakes (bodyguard companions), a general and possible half-brother of Alexander the Great, was appointed satrap of Egypt after Alexander's death in 323 BC.
Battle of ActiumThe Battle of Actium was a naval battle fought between a maritime fleet of Octavian led by Marcus Agrippa and the combined fleets of both Mark Antony and Cleopatra VII Philopator. The battle took place on 2 September 31 BC in the Ionian Sea, near the former Roman colony of Actium, Greece, and was the climax of over a decade of rivalry between Octavian and Antony. In early 31 BC, the year of the battle, Antony and Cleopatra were temporarily stationed in Greece.
MouseionThe Mouseion of Alexandria (Μουσεῖον τῆς Ἀλεξανδρείας; Musaeum Alexandrium), which arguably included the Library of Alexandria, was an institution said to have been founded by Ptolemy I Soter and his son Ptolemy II Philadelphus. Originally, the word mouseion meant any place that was dedicated to the Muses, often related to the study of music or poetry, but later associated with sites of learning such as Plato's Academy and Aristotle's Lyceum.
ScrollA scroll (from the Old French escroe or escroue), also known as a roll, is a roll of papyrus, parchment, or paper containing writing. A scroll is usually partitioned into pages, which are sometimes separate sheets of papyrus or parchment glued together at the edges. Scrolls may be marked divisions of a continuous roll of writing material. The scroll is usually unrolled so that one page is exposed at a time, for writing or reading, with the remaining pages rolled and stowed to the left and right of the visible page.
ZenodotusZenodotus (Ζηνόδοτος) was a Greek grammarian, literary critic, Homeric scholar, and the first librarian of the Library of Alexandria. A native of Ephesus and a pupil of Philitas of Cos, he lived during the reigns of the first two Ptolemies, and was at the height of his reputation about 280 BC. Zenodotus was the first superintendent of the Library of Alexandria and the first critical editor (διορθωτής diorthōtes) of Homer. In 284 BC, the Ptolemaic court appointed Zenodotus as the first Director of the library and also the official tutor to the royal children.
Archimedes' screwThe Archimedes screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines. Using Archimedes screws as water pumps (Archimedes screw pump (ASP) or screw pump) dates back many centuries. As a machine used for transferring water from a low-lying body of water into irrigation ditches, water is pumped by turning a screw-shaped surface inside a pipe. In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions.
