Q:Information:  - Pythagoras of Samos ( or simply ;  in Ionian Greek) was an Ionian Greek philosopher, mathematician, and the putative founder of the movement called Pythagoreanism. Most of the information about Pythagoras was written down centuries after he lived, so very little reliable information is known about him. He was born on the island of Samos, and travelled, visiting Egypt and Greece, and maybe India. Around 530 BC, he moved to Croton, in Magna Graecia, and there established some kind of school or guild. In 520 BC, he returned to Samos.  - An academy (Attic Greek: ; Koine Greek ) is an institution of secondary education, higher learning, research, or honorary membership.  - Attic Greek is the main Greek dialect that was spoken in ancient Attica, which includes Athens. Of the ancient dialects, it is the most similar to later Greek and is the standard form of the language that is studied in ancient-Greek language courses. Attic Greek is sometimes included in the Ionic dialect. Together, Attic and Ionic are the primary influences on Modern Greek.  - The Western world or the West is a term usually referring to different nations, depending on the context, most often including at least part of Europe. There are many accepted definitions about what they all have in common. The Western world is also known as the Occident (from Latin: "occidens" "sunset, West", as contrasted with Orient).  - Alexandria (or ; Arabic: '; '; "") is the second largest city and a major economic centre in Egypt, extending about along the coast of the Mediterranean Sea in the north central part of the country. Its low elevation on the Nile delta makes it highly vulnerable to rising sea levels. Alexandria is Egypt's largest seaport, serving approximately 80% of Egypt's imports and exports. It is an important industrial center because of its natural gas and oil pipelines from Suez. Alexandria is also an important tourist destination.  - Arabic (' or ' ) is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the "lingua franca" of the Arab world. Arabic also is a liturgical language of 1.7 billion Muslims. It is one of six official languages of the United Nations. It is named after the Arabs, a term initially used to describe peoples living from Mesopotamia in the east to the Anti-Lebanon mountains in the west, and from northwestern Arabia to the Sinai in the south.  - Byzantium ("Byzántion") was an ancient Greek colony on the site that later became Constantinople, and later still Istanbul. Byzantium was colonised by the Greeks from Megara in .  - Classical Greece was a period of around 200 years (5th and 4th centuries BC) in Greek culture. This Classical period saw the annexation of much of modern-day Greece by the Persian Empire and its subsequent independence. Classical Greece had a powerful influence on the Roman Empire and on the foundations of western civilization. Much of modern Western politics, artistic thought (architecture, sculpture), scientific thought, theatre, literature, and philosophy derives from this period of Greek history. In the context of the art, architecture, and culture of Ancient Greece, the Classical period, sometimes called the Hellenic period, corresponds to most of the 5th and 4th centuries BC (the most common dates being the fall of the last Athenian tyrant in 510 BC and the death of Alexander the Great in 323 BC). The Classical period in this sense follows the Archaic period and is in turn succeeded by the Hellenistic period.  - Not to be confused with Olympiodorus the Elder Olympiodorus the Younger ( Greek :    ; c. 495 -- 570 ) was a Neoplatonist philosopher , astrologer and teacher who lived in the early years of the Byzantine Empire , after Justinian 's Decree of 529 AD which closed Plato 's Academy in Athens and other pagan schools . Olympiodorus was the last pagan to maintain the Platonist tradition in Alexandria ( see Alexandrian School ) ; after his death the School passed into the hands of Christian Aristotelians , and was eventually moved to Constantinople .  - The Roman Empire (Koine and Medieval Greek:   , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic.  - Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek.  - Constantinople  was the capital city of the Roman/Byzantine Empire (3301204 and 12611453), and also of the brief Latin (12041261), and the later Ottoman (14531923) empires. It was reinaugurated in 324 AD from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330 AD.  - Plato (Greek: "Plátn", in Classical Attic; 428/427 or 424/423  348/347 BCE) was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, especially the Western tradition. Unlike nearly all of his philosophical contemporaries, Plato's entire "œuvre" is believed to have survived intact for over 2,400 years.  - The Nile ( "en-Nl",  "an-Nl" "P(h)iaro"; Ancient Egyptian: "'p" and "Iteru"; Biblical Hebrew: , "Ha-Ye'or") is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, however other conflicting sources cite a 2007 study that gave the title to the Amazon River in South America. The Nile, which is 6,853 km (4,258 miles) long, is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the "Roman Empire" (tr. ), or "Romania", and to themselves as "Romans".  - An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Brazilian Empire, Russian Empire, Ottoman Empire, Byzantine Empire or Roman Empire." An empire can be made solely of contiguous territories such as the Austro-Hungarian Empire, or of territories far remote from the homeland, such as a colonial empire.  - Biblical Hebrew ("Ivrit Miqra'it" or "Leshon ha-Miqra"), also called Classical Hebrew, is an archaic form of Hebrew, a Canaanite Semitic language spoken by the Israelites in the area known as Israel, roughly west of the Jordan River and east of the Mediterranean Sea. The term "Hebrew" was not used for the language in the Bible, which was referred to as Canaanite or Judahite, but the name was used in Greek and Mishnaic Hebrew texts. Biblical Hebrew is attested from about the 10th century BCE, and persisted through and beyond the Second Temple period, which ended in the siege of Jerusalem (AD 70).  - A philosopher is someone who practices philosophy, which involves rational inquiry into areas that are outside of either theology or science. The term "philosopher" comes from the Ancient Greek ("philosophos") meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BC).  - A Christian (or ) is a person who follows or adheres to Christianity, an Abrahamic, monotheistic religion based on the life and teachings of Jesus Christ. "Christian" derives from the Koine Greek word "Christós" (), a translation of the Biblical Hebrew term "mashiach".  - Philosophy (from Greek , "philosophia", literally "love of wisdom") is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The term was probably coined by Pythagoras (c. 570  c. 495 BC). Philosophical methods include questioning, critical discussion, rational argument and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? However, philosophers might also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if one can get away with it)? Do humans have free will?    What is the relationship between 'olympiodorus the younger' and 'medieval greek'?
