Library of Alexandria
The Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts. The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the library, but the library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height.
Alexandria came to be regarded as the capital of knowledge and learning, in part because of the Great Library. Many important and influential scholars worked at the Library during the third and second centuries BC, including: Zenodotus of Ephesus, who worked towards standardizing the works of Homer; Callimachus, who wrote the Pinakes, sometimes considered the world's first library catalog; Apollonius of Rhodes, who composed the epic poem the Argonautica; Eratosthenes of Cyrene, who calculated the circumference of the earth within a few hundred kilometers of accuracy; Hero of Alexandria, who invented the first recorded steam engine; Aristophanes of Byzantium, who invented the system of Greek diacritics and was the first to divide poetic texts into lines; and Aristarchus of Samothrace, who produced the definitive texts of the Homeric poems as well as extensive commentaries on them. During the reign of Ptolemy III Euergetes, a daughter library was established in the Serapeum, a temple to the Greco-Egyptian god Serapis.
The influence of the Library declined gradually over the course of several centuries. This decline began with the purging of intellectuals from Alexandria in 145 BC during the reign of Ptolemy VIII Physcon, which resulted in Aristarchus of Samothrace, the head librarian, resigning and exiling himself to Cyprus. Many other scholars, including Dionysius Thrax and Apollodorus of Athens, fled to other cities, where they continued teaching and conducting scholarship. The Library, or part of its collection, was accidentally burned by Julius Caesar during his civil war in 48 BC, but it is unclear how much was actually destroyed and it seems to have either survived or been rebuilt shortly thereafter. The geographer Strabo mentions having visited the Mouseion in around 20 BC, and the prodigious scholarly output of Didymus Chalcenterus in Alexandria from this period indicates that he had access to at least some of the Library's resources.
The Library dwindled during the Roman period, from a lack of funding and support. Its membership appears to have ceased by the 260s AD. Between 270 and 275 AD, Alexandria saw a Palmyrene invasion and an imperial counterattack that probably destroyed whatever remained of the Library, if it still existed. The daughter library in the Serapeum may have survived after the main Library's destruction. The Serapeum, mainly used as a gathering place for Neoplatonist philosophers following the teachings of Iamblichus, was vandalized and demolished in 391 AD under a decree issued by bishop Theophilus of Alexandria.
Historical background
The Library of Alexandria was not the first library of its kind. A long tradition of libraries existed in both Greece and in the ancient Near East. The earliest recorded archive of written materials comes from the ancient Sumerian city-state of Uruk in around 3400 BC, when writing had only just begun to develop. Scholarly curation of literary texts began in around 2500 BC. The later kingdoms and empires of the ancient Near East had long traditions of book collecting. The ancient Hittites and Assyrians had massive archives containing records written in many different languages. The most famous library of the ancient Near East was the Library of Ashurbanipal in Nineveh, founded in the seventh century BC by the Assyrian king Ashurbanipal. A large library also existed in Babylon during the reign of Nebuchadnezzar II. In Greece, the Athenian tyrant Pisistratus was said to have founded the first major public library in the sixth century BC. It was out of this mixed heritage of both Greek and Near Eastern book collections that the idea for the Library of Alexandria may have been born through Alexander.Following the death of Alexander the Great in 323 BC, there was a power grab for his empire among his top-ranking officers. The empire was divided into three: the Antigonid dynasty controlled Greece; the Seleucid dynasty, who had their capitals at Antioch and Seleucia, controlled large areas of Asia Minor, Syria, and Mesopotamia; and the Ptolemaic dynasty controlled Egypt with Alexandria as its capital. The Macedonian kings who succeeded Alexander the Great as rulers of the Near East wanted to promote Hellenistic culture and learning throughout the known world. These rulers, therefore, had a vested interest in collecting and compiling information from both the Greeks and the far more ancient kingdoms of the Near East. Libraries enhanced a city's prestige, attracted scholars, and provided practical assistance in ruling and governing the kingdom. Eventually, for these reasons, every major Hellenistic urban center would have a royal library. The Library of Alexandria, however, was unprecedented because of the scope and scale of the Ptolemies' ambitions; unlike their predecessors and contemporaries, the Ptolemies wanted to produce a repository of all knowledge. To support this endeavor, they were well positioned as Egypt was the ideal habitat for the papyrus plant, which provided an abundant supply of materials needed to amass their knowledge repository.
Under Ptolemaic patronage
Founding
The Library was one of the largest and most significant libraries of the ancient world, but details about it are a mixture of history and legend. The earliest known surviving source of information on the founding of the Library of Alexandria is the pseudepigraphic Letter of Aristeas, which was composed between 180 and 145 BC. It claims the Library was founded during the reign of Ptolemy I Soter and that it was initially organized by Demetrius of Phalerum, a student of Aristotle who had been exiled from Athens and taken refuge in Alexandria within the Ptolemaic court. Nonetheless, the Letter of Aristeas is very late and contains information that is now known to be inaccurate. According to Diogenes Laertius, Demetrius was a student of Theophrastus, a student of Aristotle. Other sources claim that the Library was instead created under the reign of Ptolemy I's son Ptolemy II Philadelphus.Modern scholars agree that, while it is possible that Ptolemy I, who was a historian and author of an account of Alexander's campaign, may have laid the groundwork for the Library, it probably did not come into being as a physical institution until the reign of Ptolemy II. By that time, Demetrius of Phalerum had fallen out of favor with the Ptolemaic court. He probably would not, therefore, have had any role in establishing the Library as an institution. Stephen V. Tracy, however, argues that it is highly probable that Demetrius played an important role in collecting at least some of the earliest texts that would later become part of the Library's collection. In around 295 BC, Demetrius may have acquired early texts of the writings of Aristotle and Theophrastus, which he would have been uniquely positioned to do since he was a distinguished member of the Peripatetic school.
The Library was built in the Brucheion as part of the Mouseion. Its main purpose was to show off the wealth of Egypt, with research as a lesser goal, but its contents were used to aid the ruler of Egypt. The exact layout of the library is not known, but ancient sources describe the Library of Alexandria as comprising a collection of scrolls, Greek columns, a walk, a room for shared dining, a reading room, meeting rooms, gardens, and lecture halls, creating a model for the modern university campus. A hall contained shelves for the collections of papyrus scrolls known as bibliothekai. According to popular description, an inscription above the shelves read: "The place of the cure of the soul."
Early expansion and organization
The Ptolemaic rulers intended the Library to be a collection of all knowledge and they worked to expand the Library's collections through an aggressive and well-funded policy of book purchasing. They dispatched royal agents with large amounts of money and ordered them to purchase and collect as many texts as they possibly could, about any subject and by any author. Older copies of texts were favored over newer ones, since it was assumed that older copies had undergone less copying and that they were therefore more likely to more closely resemble what the original author had written. This program involved trips to the book fairs of Rhodes and Athens. According to the Greek medical writer Galen, under the decree of Ptolemy II, any books found on ships that came into port were taken to the library, where they were copied by official scribes. The original texts were kept in the library, and the copies delivered to the owners. The Library particularly focused on acquiring manuscripts of the Homeric poems, which were the foundation of Greek education and revered above all other poems. The Library therefore acquired many different manuscripts of these poems, tagging each copy with a label to indicate where it had come from.In addition to collecting works from the past, the Mouseion which housed the Library also served as home to a host of international scholars, poets, philosophers, and researchers, who, according to the first-century BC Greek geographer Strabo, were provided with a large salary, free food and lodging, and exemption from taxes. They had a large, circular dining hall with a high domed ceiling in which they ate meals communally. There were also numerous classrooms, where the scholars were expected to at least occasionally teach students. Ptolemy II Philadelphus is said to have had a keen interest in zoology, so it has been speculated that the Mouseion may have even had a zoo for exotic animals. According to classical scholar Lionel Casson, the idea was that if the scholars were completely freed from all the burdens of everyday life they would be able to devote more time to research and intellectual pursuits. Strabo called the group of scholars who lived at the Mouseion a σύνοδος. As early as 283 BC, they may have numbered between thirty and fifty learned men.
