La risposta breve
- What it was: A royal library associated with the Mouseion, a centre of learning in Alexandria, Egypt.
- Founded: Usually dated to the early third century BC, under Ptolemy I Soter and Ptolemy II Philadelphus.
- What happened: Its decline had several stages. No single fire explains its loss, and no secure closing date survives.
- What survives: No manuscript is securely identified as a royal Library volume, but some Alexandrian scholarship survives indirectly.
The Library of Alexandria was a Ptolemaic centre of scholarship in Egypt, usually dated to the early third century BC, whose collections and eventual disappearance are only partly documented. It held papyrus rolls and supported work across literature and other fields. Its decline was not one securely documented catastrophe, and its contents cannot be reconstructed from a surviving inventory. The modern Bibliotheca Alexandrina is a separate institution, not the ancient collection preserved.
This guide moves from the Library's foundation and collections to the scholars who worked there, then through its decline and surviving traces. It closes with Alexandria today and related ancient writings represented on this website, separating documented connections from associations the evidence cannot establish.
What the Library of Alexandria was
The royal Library belonged to the Mouseion, often called the Museum, in Alexandria, Egypt. Its name came from the Muses, the Greek divine patrons of intellectual and artistic pursuits. The institution belonged to a Greek-speaking scholarly culture, although the surrounding city was multilingual. Royal patronage supported its scholars, connecting the collection with a community engaged in research rather than simply the storage of books.
Strabo describes a covered walkway, a meeting space and a shared dining hall for the Mouseion's scholars. These details provide a partial picture, not a complete plan of the Library building. Archaeology has not securely established its precise location or architectural layout. Much of its history depends on scattered literary references rather than surviving administrative records.
Who built it, and when
Alexander the Great founded Alexandria in 331 BC on Egypt's Mediterranean coast. The Library came later, under the Ptolemies, the Greek dynasty that ruled Egypt after Alexander. Its foundation is usually dated to the early third century BC and associated with Ptolemy I Soter and his son Ptolemy II Philadelphus. Alexander's foundation of the city was not the foundation of the Library.
The attribution to these two rulers reflects a history less precisely documented than a single opening ceremony or construction date. The evidence supports a Ptolemaic foundation, but not an exact date for every stage of its establishment.
What it held
Papyrus rolls were the principal book format in the Library's early centuries. Ancient writers give totals ranging from tens of thousands to several hundred thousand scrolls; historians treat every figure as uncertain. A scroll was not equivalent to a modern book. One work might occupy several rolls, while multiple copies allowed scholars to examine differences in wording. Acquisition stories cannot establish the collection's actual size.
Its scholarly scope encompassed poetry, drama, history and geography, not only religious writings. Galen reports that books arriving by ship were taken for copying, with originals retained and copies returned. He also tells of a Ptolemaic king retaining borrowed official Athenian copies of the major tragedians. The Letter of Aristeas offers a literary translation account concerning the Jewish Law, not the entire later Septuagint.
Who worked there
Zenodotus of Ephesus is traditionally identified as the first head. Callimachus of Cyrene compiled the Pinakes, arranging authors and works by literary or scholarly category. Other associated scholars include Apollonius of Rhodes, author of the Argonautica, and Eratosthenes of Cyrene, who estimated the Earth's size. Euclid, author of the Elements, is traditionally placed in Alexandria during the reign of Ptolemy I.
Aristophanes of Byzantium and Aristarchus of Samothrace worked on Homer, whose poems were central to Alexandrian textual scholarship. Editors used critical signs to mark passages needing comment or regarded as doubtful. Hypatia belongs to a much later setting: she taught philosophy and mathematics in late antique Alexandria and was killed by a mob in 415 AD, long after the Library's greatest period.
What happened to it: several events, not one fire
The decline involved several causes and stages. Many scholars were expelled around 145 BC under Ptolemy VIII. During the Alexandrian War in 48 BC, Julius Caesar's fire burned part of the harbour area. Ancient accounts disagree about whether books were destroyed and how many. Strabo visited around 25 BC and described the Mouseion without reporting that a library had been destroyed.
Later destruction in Alexandria does not supply a secure closing date for the royal Library. Whether books remained in the Serapeum when it was destroyed in 391 AD is uncertain. Alexandria continued as a centre of philosophical, medical and religious learning in late antiquity. The evidence behind who burned the Library of Alexandria concerns several events, not one documented act that explains every loss.
What survives, and what cannot be reconstructed
No complete ancient catalogue survives, and no surviving manuscript can securely be identified as a volume from the royal Library. The Pinakes is lost as a complete work, although later writers preserve fragments and references. Some Alexandrian scholarly judgments also survive indirectly in annotations transmitted with later manuscripts. Works associated with Alexandrian scholarship that survive include the Argonautica and the Elements.
There is no inventory showing exactly which works disappeared. Losing a copy in Alexandria did not necessarily destroy a work circulating elsewhere, and the loss of ancient literature cannot collectively be attributed to this Library. Papyri recovered elsewhere in Egypt preserve otherwise lost or incomplete writings, but those discoveries do not establish that the manuscripts originated in the royal collection.
The Library of Alexandria today
The Bibliotheca Alexandrina opened in 2002 near the ancient Library's site in Alexandria. Its facilities encompass museums, research spaces and library collections. It is not a surviving collection transferred from the royal Library.
Other discoveries also have separate histories. The Dead Sea Scrolls were discovered beginning in 1947 near the Dead Sea. The Nag Hammadi manuscripts are Coptic codices discovered in Upper Egypt in 1945. Neither discovery recovered holdings of the Library of Alexandria.
Where to go from here
This website takes the Library of Alexandria's name; it does not continue or descend from the ancient institution. Its guide to the lost books of the Bible addresses related writings, while guides to the Septuagint and the Books of Enoch provide more specific subjects. The works called 1 Enoch, 2 Enoch and 3 Enoch are distinct compositions, not volumes of one ancient book.
The edition on this site titled The Complete Books of Enoch brings those works together with the Book of Giants. The Complete 88-Book Ethiopian Bible presents a collection containing Enoch, Jubilees and Meqabyan. The Dead Sea Scrolls Bible gathers biblical texts preserved at Qumran; The Nag Hammadi Scriptures gathers religious writings preserved in Coptic manuscripts. These titles concern ancient textual traditions, not recovered royal Library volumes.

Questions about the Library of Alexandria
Who built the Library of Alexandria?
Its foundation is usually associated with Ptolemy I Soter and his son Ptolemy II Philadelphus in the early third century BC. It developed under the Ptolemaic dynasty as part of the Mouseion. Alexander the Great founded Alexandria itself in 331 BC, not the Library.
How many books were in the Library of Alexandria?
The total is unknown. Ancient writers report tens of thousands to several hundred thousand scrolls, but historians regard these figures as uncertain. Scroll totals also cannot be converted directly into numbers of works: a work could fill several rolls, and the collection held multiple copies.
Who burned the Library of Alexandria?
No single person can securely be credited with destroying the whole Library. Caesar's fire in 48 BC affected the harbour, but ancient accounts disagree about book losses. The institution declined through several stages, and no securely documented date establishes when the royal Library ceased functioning.
Was the Library of Alexandria real?
Yes. The Library was a real institution associated with the Ptolemaic Mouseion, although many details remain uncertain. Scattered ancient literary references provide most of the evidence. They do not supply a complete catalogue, a securely established architectural plan or an uninterrupted administrative history of the collection.
Where was the Library of Alexandria?
It was in Alexandria, on Egypt's Mediterranean coast, associated with the royal Mouseion. Its precise location and architectural layout have not been securely established by archaeology. The modern Bibliotheca Alexandrina stands near the ancient site, but it is not the ancient Library building or its surviving collection.
Is there a Library of Alexandria today?
Yes. The Bibliotheca Alexandrina opened in Alexandria in 2002 as a centre for learning and culture. It contains museums and research facilities as well as collections. It is separate from the ancient royal Library, whose manuscripts cannot securely be identified among surviving volumes today.
