A relatively recent new discipline within the classics is "reception studies", which developed in the 1960s at the University of Konstanz. Reception studies is concerned with how students of classical texts have understood and interpreted them. As such, reception studies is interested in a two-way interaction between reader and text, taking place within a historical context. Though the idea of an "aesthetics of reception" was first put forward by Hans Robert Jauss in 1967, the principles of reception theory go back much earlier than this. As early as 1920, T. S. Eliot wrote that "the past [is] altered by the present as much as the present is directed by the past"; Charles Martindale describes this as a "cardinal principle" for many versions of modern reception theory. Ancient Greece was the civilization belonging to the period of Greek history lasting from the Archaic period, beginning in the eighth century BC, to the Roman conquest of Greece after the Battle of Corinth in 146 BC. The Classical period, during the fifth and fourth centuries BC, has traditionally been considered the height of Greek civilisation. The Classical period of Greek history is generally considered to have begun with the first and second Persian invasions of Greece at the start of the Greco-Persian wars, and to have ended with the death of Alexander the Great. Classical Greek culture had a powerful influence on the Roman Empire, which carried a version of it to many parts of the Mediterranean region and Europe; thus Classical Greece is generally considered to be the seminal culture which provided the foundation of Western civilization. Ancient Greek is the historical stage in the development of the Greek language spanning the Archaic (c. 8th to 6th centuries BC), Classical (c. 5th to 4th centuries BC), and Hellenistic (c. 3rd century BC to 6th century AD) periods of ancient Greece and the ancient world. It is predated in the 2nd millennium BC by Mycenaean Greek. Its Hellenistic phase is known as Koine ("common") or Biblical Greek, and its late period mutates imperceptibly into Medieval Greek. Koine is regarded as a separate historical stage of its own, although in its earlier form it closely resembles Classical Greek. Prior to the Koine period, Greek of the classical and earlier periods included several regional dialects. Ancient Greek was the language of Homer and of classical Athenian historians, playwrights, and philosophers. It has contributed many words to the vocabulary of English and many other European languages, and has been a standard subject of study in Western educational institutions since the Renaissance.
