Late antiquity in the context of "Sasanian Empire"

Western culture, also known as Western civilization, European civilization, Occidental culture, Western society, or simply the West, is the internally diverse culture of the Western world. The term "Western" encompasses the social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies primarily rooted in European and Mediterranean histories. A broad concept, "Western culture" does not relate to a region with fixed members or geographical confines. It generally refers to the classical era cultures of Ancient Greece, Ancient Rome, and their Christian successors that expanded across the Mediterranean basin and Europe, and later circulated around the world predominantly through colonization and globalization.

Historically, scholars have closely associated the idea of Western culture with the classical era of Greco-Roman antiquity. However, scholars also acknowledge that other cultures, like Ancient Egypt, the Phoenician city-states, and several Near-Eastern cultures stimulated and influenced it. The Hellenistic period also promoted syncretism, blending Greek, Roman, and Jewish cultures. Major advances in literature, engineering, and science shaped the Hellenistic Jewish culture from which the earliest Christians and the Greek New Testament emerged. The eventual Christianization of Europe in late-antiquity would ensure that Christianity, particularly the Catholic Church, remained a dominant force in Western culture for many centuries to follow.

Ancient Greek mathematics refers to the history of mathematical ideas and texts in Ancient Greece during classical and late antiquity, mostly from the 5th century BC to the 6th century AD. Greek mathematicians lived in cities spread around the shores of the ancient Mediterranean, from Anatolia to Italy and North Africa, but were united by Greek culture and the Greek language. The development of mathematics as a theoretical discipline and the use of deductive reasoning in proofs is an important difference between Greek mathematics and those of preceding civilizations.

The early history of Greek mathematics is obscure, and traditional narratives of mathematical theorems found before the fifth century BC are regarded as later inventions. It is now generally accepted that treatises of deductive mathematics written in Greek began circulating around the mid-fifth century BC, but the earliest complete work on the subject is Euclid's Elements, written during the Hellenistic period. The works of renown mathematicians Archimedes and Apollonius, as well as of the astronomer Hipparchus, also belong to this period. In the Imperial Roman era, Ptolemy used trigonometry to determine the positions of stars in the sky, while Nicomachus and other ancient philosophers revived ancient number theory and harmonics. During late antiquity, Pappus of Alexandria wrote his Collection, summarizing the work of his predecessors, while Diophantus' Arithmetica dealt with the solution of arithmetic problems by way of pre-modern algebra. Later authors such as Theon of Alexandria, his daughter Hypatia, and Eutocius of Ascalon wrote commentaries on the authors making up the ancient Greek mathematical corpus.

The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.

During the early centuries of the Roman Empire, the western provinces were Latinised, but the eastern parts kept their Hellenistic culture. Constantine I (r. 324–337) legalised Christianity and moved the capital to Constantinople. Theodosius I (r. 379–395) made Christianity the state religion and Greek gradually replaced Latin for official use. The empire adopted a defensive strategy and, throughout its remaining history, experienced recurring cycles of decline and recovery.

Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BC – AD 500, ending with the 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 usually 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.

Alexandria is a major city in Egypt. Lying at the western edge of the Nile River Delta, it extends about 40 km (25 mi) along the country's northern coast. It is Egypt's principal seaport, the second largest city after Cairo, and the largest city on the Mediterranean coast. Founded in 331 BC by Alexander the Great, Alexandria is one of the largest and most important cities of antiquity and a leading hub for science, culture, and scholarship.

Nicknamed the "Bride of the Mediterranean" and "Pearl of the Mediterranean Coast", the city is a popular tourist destination and a major industrial centre. It is the sixth-largest city in the Arab world and in the Middle East, and the eleventh-largest city and urban area in Africa. Alexandria was established originally near an ancient Egyptian settlement named Rhacotis, which later became its Egyptian quarter. The city was made the capital of the Ptolemaic Kingdom and became the foremost commercial, intellectual, and cultural centre for much of the Hellenistic age and late antiquity; at one time, it was the most populous city in the ancient world. Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World; its Great Library, the largest in the ancient world; and the Catacombs of Kom El Shoqafa, one of the Seven Wonders of the Middle Ages.

Classical antiquity, also known as the classical era, classical period, classical age, or simply antiquity, is the period of cultural European history between the 8th century BC and the 5th century AD. It comprises the interwoven civilizations of ancient Greece and Rome, known together as the Greco-Roman world, which played a major role in shaping the culture of the Mediterranean basin. It is the period during which ancient Greece and Rome flourished and had major influence throughout much of Europe, North Africa, and West Asia. Classical antiquity was succeeded by Late antiquity.

Conventionally, it is often considered to begin with the earliest recorded Epic Greek poetry of Homer (8th–7th centuries BC) and end with the fall of the Western Roman Empire in 476 AD. Such a wide span of history and territory covers many disparate cultures and periods. Classical antiquity may also refer to an idealized vision among later people of what was, in Edgar Allan Poe's words, "the glory that was Greece, and the grandeur that was Rome".

Greece in the Roman era (Greek: Έλλάς, Latin: Graecia) describes the period of ancient Greece (roughly, the territory of the modern nation-state of Greece) as well as that of the Greek people and the areas they inhabited and ruled historically, from the Roman Republic's conquest of mainland Greece in 146 BC until the division of the Roman Empire in late antiquity. It covers the periods when Greece was dominated first by the Roman Republic and then by the Roman Empire.

In the history of Greece, the Roman era began with the Corinthian defeat in the Battle of Corinth in 146 BC. However, before the Achaean War, the Roman Republic had been steadily gaining control of mainland Greece by defeating the Kingdom of Macedon in a series of conflicts known as the Macedonian Wars. The Fourth Macedonian War ended at the Battle of Pydna in 148 BC with the defeat of the Macedonian royal pretender Andriscus.

The Early Middle Ages (or early medieval period), sometimes controversially referred to as the Dark Ages, is typically regarded by historians as lasting from the late 5th to the 10th century. They marked the start of the Middle Ages of European history, following the decline of the Western Roman Empire, and preceding the High Middle Ages (c. 11th to 14th centuries). The alternative term late antiquity, for the early part of the period, emphasizes elements of continuity with the Roman Empire, while Early Middle Ages is used to emphasize developments characteristic of the earlier medieval period.

The period saw a continuation of trends evident since late classical antiquity, including population decline, especially in urban centres, a decline of trade, a small rise in average temperatures in the North Atlantic region and increased migration. In the 19th century the Early Middle Ages were often labelled the Dark Ages, a characterization based on the relative scarcity of literary and cultural output from this time. The term is rarely used by academics today. The Eastern Roman Empire, or Byzantine Empire, survived, though in the 7th century the Rashidun Caliphate and the Umayyad Caliphate conquered the southern part of the Roman territory.
