Lyceum (classical) in the context of "Ancient Athens"

Classical Athens, known contemporaneously simply as Athens (Ancient Greek: Ἀθῆναι, Athênai [atʰɛ̂ːnai̯]; Modern Greek: Αθήναι, Athine [aˈθine]), was the major urban centre of the notable polis (city-state) of the same name during the classical period (480–323 BC) of ancient Greece, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions, it remained in place for 180 years, until 322 BC (amid the aftermath of the Lamian War). The peak of Athenian hegemony was achieved during the Age of Pericles in the 440s and 430s BC.

In the classical period, Athens was a centre for the arts, learning, and philosophy, and it was the home of Plato's Academy and Aristotle's Lyceum. Athens was also the birthplace of Socrates, Plato, Pericles, Aristophanes, Sophocles, and many other prominent philosophers, writers, and politicians of the ancient world. It is widely referred to as the cradle of Western civilization and as the birthplace of democracy, largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC on the rest of the then-known European continent.

Aristotle (Attic Greek: Ἀριστοτέλης, romanized: Aristotélēs; 384–322 BC) was an ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.

Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato's Academy in Athens and remained there until the age of thirty seven (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls.

The Peripatetic school (Ancient Greek: Περίπατος lit. 'walkway') was a philosophical school founded in 335 BC by Aristotle in the Lyceum in ancient Athens. It was an informal institution whose members conducted philosophical and scientific inquiries. The school fell into decline after the middle of the 3rd century BC, but had a revival in the Roman Empire.

The Apollo Lyceus (Greek: Ἀπόλλων Λύκειος, Apollōn Lukeios) type, also known as Lycean Apollo, originating with Praxiteles and known from many full-size statue and figurine copies as well as from 1st century BCE Athenian coinage, is a statue type of Apollo showing the god resting on a support (a tree trunk or tripod), his right forearm touching the top of his head and his hair fixed in braids on the top of a head in a haircut typical of childhood. It is called "Lycean" not after Lycia itself, but after its identification with a lost work described, though not attributed to a sculptor, by Lucian as being on show in the Lyceum, one of the gymnasia of Athens. According to Lucian, the god leaning on a support with his bow in his left hand and his right resting on his head is shown "as if resting after long effort." Its main exemplar is the Apollino in Florence or Apollo Medici, in the Uffizi, Florence.

The attribution, based on the type's "elongated proportions, elegant pose and somewhat effeminate anatomy", as Brunilde Sismondo Ridgway characterised it, is traditionally supported on the grounds of the type's similarity to Praxiteles's Hermes from Olympia – one replica of the Lycian Apollo even passed as a copy of the Hermes for a time. The comparison essentially rests on the Apollino, whose head has proportions similar to those of the Aphrodite of Cnidus and whose pronounced sfumato confirms the long-held idea that it is Praxitelean in style, in spite of the many differences among the extant examples.

The works of Aristotle, sometimes referred to by modern scholars with the Latin phrase Corpus Aristotelicum, is the collection of Aristotle's works that have survived from antiquity.

According to a distinction that originates with Aristotle himself, his writings are divisible into two groups: the "exoteric" and the "esoteric". Most scholars have understood this as a distinction between works Aristotle intended for the public (exoteric), and the more technical works intended for use within the Lyceum (esoteric). Modern scholars commonly assume these latter to be Aristotle's own (unpolished) lecture notes (or in some cases possible notes by his students). However, one classic scholar offers an alternative interpretation. The 5th century neoplatonist Ammonius Hermiae writes that Aristotle's writing style is deliberately obscurantist so that "good people may for that reason stretch their mind even more, whereas empty minds that are lost through carelessness will be put to flight by the obscurity when they encounter sentences like these".

The Mouseion of Alexandria (Ancient Greek: Μουσεῖον τῆς Ἀλεξανδρείας; Latin: Musaeum Alexandrinum), which arguably included the Library of Alexandria, was an institution said to have been founded by Ptolemy I Soter and his son Ptolemy II Philadelphus. Originally, the word mouseion meant any place that was dedicated to the Muses, often related to the study of music or poetry, but later associated with sites of learning such as Plato's Academy and Aristotle's Lyceum.

The Ptolemies reputedly established their Mouseion and Library with the intention of bringing together some of the best scholars of the Hellenistic world and to collect all the books known at the time. Although it did not imply a collection of works of art, the word mouseion is the root for the modern usage of the word museum.

Theophrastus (/ˌθiː.əˈfræstəs/; Ancient Greek: Θεόφραστος, romanized: Theophrastos, lit. 'godly phrased'; c. 371 – c. 287 BC) was an ancient Greek philosopher and naturalist. A native of Eresos in Lesbos, he was Aristotle's close colleague and successor as head of the Lyceum, the Peripatetic school of philosophy in Athens. Theophrastus wrote numerous treatises across all areas of philosophy, working to support, improve, expand, and develop the Aristotelian system. He made significant contributions to various fields, including ethics, metaphysics, botany, and natural history. Often considered the "father of botany" for his groundbreaking works "Enquiry into Plants" (Ancient Greek: Περὶ φυτῶν ἱστορία, romanized: Peri phytōn historia) and "On the Causes of Plants", (Ancient Greek: Περὶ αἰτιῶν φυτικῶν, romanized: Peri aitiōn phytikōn) Theophrastus established the foundations of botanical science. His given name was Tyrtamos (Ancient Greek: Τύρταμος); the nickname Theophrastus ("divine speaker") was reputedly given to him by Aristotle in recognition of his eloquent style.

He came to Athens at a young age and initially studied in Plato's school. After Plato's death, he attached himself to Aristotle who took to Theophrastus in his writings. When Aristotle fled Athens, Theophrastus took over as head of the Lyceum. Theophrastus presided over the Peripatetic school for thirty-six years, during which time the school flourished greatly. He is often considered the father of botany for his works on plants. After his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus.
