Ancient history in the context of "Battering ram"

Recorded history or written history describes the historical events that have been recorded in a written form or other documented communication which are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BCE, and it coincides with the invention of writing.

For some geographic regions or cultures, written history is limited to a relatively recent period in human history because of the limited use of written records. Moreover, human cultures do not always record all of the information which is considered relevant by later historians, such as the full impact of natural disasters or the names of individuals. Recorded history for particular types of information is therefore limited based on the types of records kept. Because of this, recorded history in different contexts may refer to different periods of time depending on the topic.

The Thracians (/ˈθreɪʃənz/; Ancient Greek: Θρᾷκες, romanized: Thrāikes; Latin: Thrācēs) were an Indo-European speaking people who inhabited large parts of Southeast Europe in ancient history. Thracians resided mainly in Southeast Europe in modern-day Bulgaria, Romania, North Macedonia, northern Greece and European Turkey, but also in north-western Anatolia (Asia Minor) in Turkey.

The exact origin of the Thracians is uncertain, but it is believed that Thracians like other Indo-European speaking groups in Europe descended from a mixture of Proto-Indo-Europeans and Early European Farmers.

This is a list of peoples who inhabited Anatolia in antiquity. The essential purpose of the list is to identify prehistoric cultures in the region but many of the peoples continued to inhabit Anatolia into and through classical and late antiquity, so the actual scope of the list encompasses the history of Anatolia from prehistory to the Eastern Roman Empire (4th to 7th centuries AD), during which transition to the early medieval occurred.

Anatolia was inhabited by numerous peoples and its history is characterised by different waves of population movement. The earliest recorded inhabitants of Anatolia were the Hattians and Hurrians, non-Indo-European peoples who lived in Anatolia as early as c. 2300 BC. Indo-European Hittites came to Anatolia and gradually absorbed the Hattians and Hurrians c. 2000 – c. 1700 BC. Besides Hittites, Anatolian peoples included Luwians, Palaic peoples and Lydians. They spoke Anatolian languages. Other incoming people include Armenians, Greeks, Phrygians and Thracians.

Geocentrism is a superseded astronomical model description of the Universe with Earth at the center. It is also known as the geocentric model, often exemplified specifically by the Ptolemaic system. Under most geocentric models, the Sun, the Moon, stars, and planets all orbit Earth. The geocentric model was the predominant description of the cosmos in many European ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt, as well as during the Islamic Golden Age.

Two observations supported the idea that Earth was the center of the Universe. First, from anywhere on Earth, the Sun appears to revolve around Earth once per day. While the Moon and the planets have their own motions, they also appear to revolve around Earth about once per day. The stars appeared to be fixed on a celestial sphere rotating once each day about an axis through the geographical poles of Earth. Second, Earth seems to be unmoving from the perspective of an earthbound observer; it feels solid, stable, and stationary.

The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.

The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

The ancient Near East was home to many cradles of civilization, spanning Mesopotamia, the Levant,, Egypt, Iran, Anatolia and the Armenian highlands, and the Arabian Peninsula. As such, the fields of ancient Near East studies and Near Eastern archaeology are one of the most prominent with regard to research in the realm of ancient history. Historically, the Near East denoted an area roughly encompassing the centre of West Asia, having been focused on the lands between Greece and Egypt in the west and Iran in the east. It therefore largely corresponds with the modern-day geopolitical concept of the Middle East.

The history of the ancient Near East begins with the rise of Sumer in the 4th millennium BC, though the date that it ends is a subject of debate among scholars; the term covers the region's developments in the Bronze Age and the Iron Age, and is variously considered to end with either the establishment of the Achaemenid Empire in the 6th century BC, the establishment of the Macedonian Empire in the 4th century BC, or the beginning of the early Muslim conquests in the 7th century AD.

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.

Aelius Galenus or Claudius Galenus (Greek: Κλαύδιος Γαληνός; September 129 – c. 216 AD), often anglicized as Galen (/ˈɡeɪlən/) or Galen of Pergamon, was a Roman and Greek physician, surgeon, and philosopher. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic.

The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors.

Classics, also classical studies or Ancient Greek and Roman studies, is the study of classical antiquity. In the Western world, classics traditionally refers to the study of Ancient Greek and Roman literature and their original languages, Ancient Greek and Latin. Classics may also include as secondary subjects Greco-Roman philosophy, history, archaeology, anthropology, architecture, art, mythology, and society.

In Western civilization, the study of the Ancient Greek and Roman classics was considered the foundation of the humanities, and they traditionally have been the cornerstone of an elite higher education.
