Ancient Near East in the context of "Median kingdom"

Science in classical antiquity encompasses inquiries into the workings of the world or universe aimed at both practical goals (e.g., establishing a reliable calendar or determining how to cure a variety of illnesses) as well as more abstract investigations belonging to natural philosophy. Classical antiquity is traditionally defined as the period between the 8th century BC (beginning of Archaic Greece) and the 6th century AD (after which there was medieval science). It is typically limited geographically to the Greco-Roman West, Mediterranean basin, and Ancient Near East, thus excluding traditions of science in the ancient world in regions such as China and the Indian subcontinent.

Ideas regarding nature that were theorized during classical antiquity were not limited to science but included myths as well as religion. Those who are now considered as the first scientists may have thought of themselves as natural philosophers, as practitioners of a skilled profession (e.g., physicians), or as followers of a religious tradition (e.g., temple healers). Some of the more widely known figures active in this period include Hippocrates, Aristotle, Euclid, Archimedes, Hipparchus, Galen, and Ptolemy. Their contributions and commentaries spread throughout the Eastern, Islamic, and Latin worlds and contributed to the birth of modern science. Their works covered many different categories including mathematics, cosmology, medicine, and physics.

In classical antiquity, the Hellenistic period covers the time in Greek, Eastern Mediterranean, and West Asian (or Middle Eastern) history following Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII in 30 BC, in which these regions were under the influence of Greek leadership, culture, and language. The Hellenistic period was followed by the ascendancy of the Roman Empire, the Battle of Actium in 31 BC, and the Roman conquest of Ptolemaic Egypt the following year, which eliminated the last major Hellenistic kingdom. Its name stems from the Ancient Greek word Hellas (Ἑλλάς, Hellás), which was gradually recognized as the name for Greece, from which the modern historiographical term Hellenistic was derived. The term "Hellenistic" is to be distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all the ancient territories of the period that had come under significant Greek influence, particularly the Hellenized Ancient Near East, after the conquests of Alexander the Great.

After the Macedonian conquest of the Achaemenid Empire in 330 BC and its disintegration shortly thereafter in the Partition of Babylon and subsequent Wars of the Diadochi, Hellenistic kingdoms were established throughout West Asia (Seleucid Empire, Kingdom of Pergamon), Northeast Africa (Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo-Greek Kingdom). This resulted in an influx of Greek colonists and the export of Greek culture and language to these new realms, a breadth spanning as far as modern-day India. These new Greek kingdoms were also influenced by regional indigenous cultures, adopting local practices which were deemed beneficial, necessary, or convenient. Hellenistic culture thus represents a fusion of the ancient Greek world with that of the Western Asian, Northeastern African, and Southwestern Asian worlds. The consequence of this mixture gave rise to a common Attic-based Greek dialect, known as Koine Greek, which became the lingua franca throughout the ancient world.

The Achaemenid Empire (/əˈkiːmənɪd/ ə-KEE-mə-nid; Old Persian: 𐎧𐏁𐏂, Xšāça, lit. 'The Empire' or 'The Kingdom') was an ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. At peak, its territorial extent was roughly 5.5 million square kilometres (2.1 million square miles), making it the largest empire of its time. Based in the Iranian plateau, it stretched from the Balkans and Egypt in the west to the Indus Valley in the east, including Anatolia, Cyprus, Mesopotamia, the Levant, parts of Eastern Arabia, and large parts of Central Asia.

By the 7th century BC, the region of Persis, located in the southwestern part of the Iranian plateau, had been settled by Persians. From Persis, Cyrus rose and defeated Media, Lydia, and the Neo-Babylonian Empire, thus marking the establishment of a new imperial polity in the ancient Near East. While its conquests were largely successful in most regions, the Achaemenid Empire's attempts to expand into Greece proved extremely difficult over the course of decades of wars and multiple kings, ultimately resulting in its defeat in the Greek mainland.

The Bronze Age is an archaeological and anthropological term defining a phase in the development of material culture among ancient societies in Asia, the Near East and Europe. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere. The Bronze Age is the middle principal period of the three-age system, following the Stone Age and preceding the Iron Age. Conceived as a global era, the Bronze Age follows the Neolithic ("New Stone") period, with a transition period between the two known as the Chalcolithic ("copper-Stone") Age. These technical developments took place at different times in different places, and therefore each region's history is framed by a different chronological system.

Bronze Age cultures were the first to develop writing. According to archaeological evidence, cultures in Mesopotamia, which used cuneiform script, and Egypt, which used hieroglyphs, developed the earliest practical writing systems. In the archaeology of the Americas, a five-period system is conventionally used instead, which does not include a Bronze Age, though some cultures there did smelt copper and bronze. No evidence of metalworking has been found on the Australian continent prior to the establishment of European settlements in 1788.

Persians, or the Persian people, are an Iranian ethnic group from West Asia. They are indigenous to the Iranian plateau and comprise the majority of the population of Iran. They have a common cultural system and are native speakers of the Persian language. In the Western world, "Persian" was largely understood as a demonym for all Iranians rather than as an ethnonym for the Persian people, but this understanding shifted in the 20th century.

The Persians were originally an ancient Iranian people who had migrated to Persis (also called "Persia proper" and corresponding with Iran's Fars Province) by the 9th century BCE. Together with their compatriots, they established and ruled some of the world's most powerful empires, which are well-recognized for their massive cultural, political, and social influence in the ancient Near East and beyond. The Persian people have contributed greatly to art and science, and Persian literature is one of the world's most prominent literary traditions both inside and outside of Iran. The regional prestige of their civilization was the basis for the development of many noteworthy Persianate societies, especially among the Turkic peoples, throughout Central Asia and South Asia.

Science in the ancient world encompasses the earliest history of science from the protoscience of prehistory and ancient history to late antiquity. In ancient times, culture and knowledge were passed through oral tradition. The development of writing further enabled the preservation of knowledge and culture, allowing information to spread accurately.

The earliest scientific traditions of the ancient world developed in the Ancient Near East, with Ancient Egypt and Babylonia in Mesopotamia. Later traditions of science during classical antiquity were advanced in ancient Persia, Greece, Rome, India, China, and Mesoamerica. Aside from alchemy and astrology that waned in importance during the Age of Enlightenment, civilizations of the ancient world laid the roots of modern sciences.
