Pergamum was home to a library said to house approximately 200,000 volumes, according to the writings of Plutarch. Built by Eumenes II between 220 and 159 BC and situated at the northern end of the Acropolis, it became one of the most important libraries in the ancient world. The cultured Pergamene rulers built up the library to be second only to the Great Library at Alexandria. Flavia Melitene, who was a distinguished citizen of Pergamum and wife of a town councillor, was instrumental in supplying the library. She also presented a statue of Hadrian to the library as a gift. It is known that a certain Artemon was employed in the library during the second century B.C. though his personification is obscure. No index or catalog of the holdings at Pergamum exists today, making it impossible to know the true size or scope of this collection. The library consisted of four rooms, the largest of which was the main reading room, lined with many shelves. An empty space of approximately was left between the outer walls and the shelves to allow for air circulation, intending to prevent the library from becoming overly humid in the warm climate of Anatolia, an early attempt at library preservation. A 3-meter statue of Athena, modeled after her statue in the Parthenon, stood in the main reading room. Manuscripts were written on parchment, rolled, and then stored on the shelves. In fact, the word "parchment" itself is derived from Pergamum. Pergamum was a thriving center of parchment production during the Hellenistic period. The city so dominated the trade that a legend later arose indicating that parchment had been invented in Pergamon to replace the use of papyrus, which had become monopolized by the rival city of Alexandria. This however is a myth; parchment had been in use in Anatolia and elsewhere long before the rise of Pergamon. Parchment reduced the Roman Empire's dependency on Egyptian papyrus and allowed for the increased dissemination of knowledge throughout Europe and Asia.
Competition
Although the library of Pergamum was built roughly a century after the library of Alexandria, the two had a fierce rivalry, as libraries were often used to reflect wealth and culture. The two libraries competed for parchment, books, and even literary interpretation. Pergamum also hired some Homeric scholars, who studied the Iliad and the Odyssey. This resulted in a fierce rivalry in which each library tried to obtain copies of Homer's works, striving to have the most accurate and oldest works. They also tried to attract better scholars by offering competitive pay. Ultimately, this rivalry forced both libraries to innovate and improve.
Decline
The Kingdom of Pergamon fell to the Romans in 133 BC and the library grew neglected. According to a legend relayed by Plutarch, Mark Antony seized the collection of 200,000 rolls and presented them as a gift to his new wife Cleopatra in 43 BC, presumably in an effort to restock the Library of Alexandria, which had been damaged during Julius Caesar's war in 48 BC. Emperor Augustus returned some of the rolls to Pergamum after the death of Antony, and the library remained extant well into the Christian era, though it was not mentioned much by later historians, indicating its collection was no longer significant. The ruins of the library sit on a hilltop near the Sanctuary of Athena and other buildings of the Pergamon Acropolis.
