In the second century BC, two cities dominated the intellectual landscape of the Hellenistic world: Alexandria in Egypt and Pergamum in Asia Minor. Their rivalry was more than political; it was a competition for cultural supremacy, measured in the number of scrolls their libraries could claim. This competition would inadvertently trigger one of the most consequential technological innovations in the history of information: the development of parchment as a writing surface. The Library of Pergamum’s legacy lies not in the texts it collected, most of which are lost, but in the material transformation it forced upon the ancient world, a change that would reshape how knowledge was recorded, preserved, and transmitted for over a millennium.
The Attalid Ambition
Pergamum, perched on a dramatic acropolis in what is now western Turkey, rose to prominence in the chaotic centuries following Alexander the Great’s death. The Attalid dynasty, which ruled the city from 282 BC, transformed it into a major Hellenistic power, wealthy from trade and agriculture, fortified against rivals, and deliberately cultivated as a centre of Greek culture and learning.
Eumenes II, who ruled from 197 to 159 BC, was particularly ambitious in this cultural project. He understood what the Ptolemies had grasped generations earlier: that a great city needed not just military might and economic power but intellectual prestige. A magnificent library would demonstrate Pergamum’s place among the leading cities of the Greek world. It would attract scholars, generate new knowledge, and establish the Attalid court as a worthy successor to the legacy of Alexander.
The library was built as part of the Sanctuary of Athena, the patron goddess of wisdom, positioned prominently on the acropolis, where it would be visible to all who approached the city. Ancient sources credit the library with holdings of 200,000 volumes—a figure that, even if exaggerated, suggests a collection rivalling or approaching Alexandria’s in scope. This wasn’t merely a royal archive serving administrative needs; it was a deliberate attempt to create a second Alexandria, a comprehensive collection that would gather and preserve Greek learning.

The Papyrus Embargo
Here, the story takes a turn that would change the history of the book. According to the ancient writer Pliny the Elder, Ptolemy V Epiphanes of Egypt became alarmed by Pergamum’s growing library, fearing it would eclipse Alexandria’s pre-eminence. In response, he imposed an embargo on papyrus exports to Pergamum. Whether this account is literally true or a later invention designed to explain what happened next, it captures a real dynamic: Alexandria and Pergamum were engaged in serious competition, and papyrus was a strategic resource controlled by Egypt.
Papyrus was made from the papyrus plant, which grew abundantly in the Nile Delta but was rare elsewhere. Egyptian control of papyrus production gave the Ptolemies leverage over the entire Mediterranean literary world. A library without access to papyrus was a library that couldn’t grow, couldn’t copy new texts, couldn’t preserve deteriorating scrolls. The embargo, if it existed, was economic warfare aimed at Pergamum’s intellectual ambitions.
Faced with this crisis, the scholars and craftsmen of Pergamum innovated. They turned to an older, less common writing material, treated animal skins, and dramatically improved the production process. The result was parchment, known in Latin as pergamena after the city that perfected it. While animal skins had been used for writing before, Pergamene craftsmen developed techniques for preparing them that produced a superior material: smoother, more durable, capable of being written on both sides, and not dependent on Egyptian exports.
The Material Revolution
Parchment was made from the skins of sheep, goats, or calves. The process was labour-intensive: skins were soaked in lime to remove hair, stretched on frames, scraped thin, and rubbed smooth with pumice. The finest parchment, made from calf skin, came to be called vellum. The result was a writing surface with properties quite different from papyrus.
Parchment was significantly more durable than papyrus. It could withstand moisture better, was less prone to cracking or crumbling with age, and could be scraped and reused, creating palimpsests, manuscripts where earlier texts were erased to make room for new ones. Many classical works survive only as traces beneath medieval religious texts on recycled parchment, recovered through modern imaging technology.
More importantly, parchment enabled a new book format: the codex. Papyrus scrolls were practical up to a point, but accessing specific passages required unrolling and rerolling. Parchment could be folded into pages and bound together, creating what we recognize as a book. This format offered enormous advantages: you could flip directly to any page, consult multiple passages quickly, compare texts side by side, and store information much more compactly. A codex containing the entire Bible would fit in the space that papyrus scrolls for the same text would require several feet of shelving to accommodate.
The codex format didn’t immediately replace scrolls, literary culture was conservative, and scrolls retained prestige for centuries. But by the fourth century CE, the codex had become dominant, particularly for Christian scriptures. Early Christians adopted the codex enthusiastically, perhaps because it allowed easier reference to specific passages for theological debate, or perhaps simply because it was more practical for carrying religious texts to clandestine meetings during periods of persecution.
The Library Itself
What was it like to enter the Library of Pergamum? Ancient sources provide tantalizing glimpses. The library occupied rooms on multiple floors within the Sanctuary of Athena. A large reading room held both the scrolls and statue of Athena herself, emphasizing the sacred nature of learning. Additional storage rooms housed the collection, with parchment rolls stored in wooden cabinets or on shelves lining the walls.
The library employed librarians and scholars, though probably not on the scale of Alexandria’s Mouseion. These professionals catalogued holdings, assisted scholars in locating texts, supervised the scriptorium where manuscripts were copied, and likely engaged in the textual criticism that characterised Hellenistic scholarship. The library collected works across the spectrum of Greek learning: literature, philosophy, history, science, medicine, and mathematics.
One scholar we know worked at Pergamum was Crates of Mallos, a grammarian and literary critic who served as head librarian around 160 BC. Crates represented a scholarly tradition that rivalled Alexandria’s; he defended Homer against Alexandrian critics and developed alternative interpretive methods. When he visited Rome on a diplomatic mission and broke his leg, he gave lectures during his convalescence, introducing Roman aristocrats to Greek literary scholarship. This cultural transmission would prove influential for the development of Latin literature.
The library also served as a political tool. The Attalid kings used it to host visiting scholars, to demonstrate their patronage of learning, and to establish Pergamum’s credentials as a proper Greek city despite its location on the margins of the Greek world. Magnificence in intellectual matters conferred legitimacy, a lesson understood by ambitious rulers throughout history.
Rivalry and Integration
The competition between Alexandria and Pergamum drove both libraries to greater ambition. Each sought texts the other lacked, pushed their scholars to produce better editions and commentaries, and vied for the services of renowned intellectuals. This rivalry benefited scholarship; it created redundancy in collection development, so that texts held by one library might survive even if the other’s copy was lost, and it fostered competitive excellence in scholarly standards.
Yet there were limits to the rivalry. Scholars moved between the two cities, carrying knowledge with them. Texts were copied and spread beyond their libraries of origin. The intellectual networks of the Hellenistic world connected rather than isolated these centres. The libraries competed, but they also participated in a larger project of preserving and advancing Greek learning.
The rivalry ended not through one library’s triumph but through political absorption. In 133 BC, Attalus III, the last Attalid king, died without an heir and bequeathed his kingdom to Rome. Pergamum became part of the Roman Empire, and its library’s fate became entangled with Roman politics and culture.
Mark Antony and the Gift
One of the most dramatic episodes in the library’s history came a century after it became Roman property. In 41 BC, Mark Antony was in Alexandria, besotted with Cleopatra VII and entangled in Egyptian politics. According to later accounts, possibly propaganda from Antony’s enemies, he gave Cleopatra 200,000 scrolls from the Library of Pergamum as a gift, allegedly to compensate for whatever had been lost from Alexandria during Caesar’s fire.
Whether this story is true remains disputed. Moving 200,000 scrolls across the Mediterranean would have been an enormous logistical undertaking. The figure might be exaggerated, or the gift might have been partial, or the story might be entirely invented by Octavian’s propagandists to portray Antony as squandering Roman resources on his foreign mistress.
Yet the story, true or not, reveals something important: by the first century BC, great libraries were recognized as treasures worth giving as gifts to monarchs. They were also becoming pawns in power struggles, their fates determined by political rather than intellectual considerations. The era of libraries as independent centres of learning was giving way to an age where they served imperial agendas.
Loss and Legacy
The Library of Pergamum, like Alexandria, ultimately vanished. No certain record survives of its final destruction. It may have declined gradually as Roman priorities shifted, suffered in one of the periodic conflicts that swept through Asia Minor, or been destroyed in the Arab conquests of the seventh century. By the Byzantine period, it was gone.
We’ve lost almost everything that made the library specifically important to its own tim, the specific texts it collected, the scholarly works produced there, the organizational systems it employed. Of the 200,000 volumes ancient sources credited to it, virtually nothing survives directly. We know far more about Alexandria, both because it operated longer and because ancient writers discussed it more extensively.
Yet the Library of Pergamum’s legacy is, paradoxically, more tangible than Alexandria’s. Every book on parchment or vellum produced over the following fifteen centuries, every illuminated medieval manuscript, every monastic codex, every luxury book of hours, was made possible by the innovations Pergamene craftsmen developed when cut off from papyrus supplies. The codex format that became universal for books descended from technologies perfected in Pergamum.
Consider what this means: when medieval monks preserved classical texts by copying them onto parchment, they were using Pergamene technology. When the Book of Kells was created, when Beowulf was written down, when Carolingian scholars copied works of Roman literature, all employed materials and formats whose development was forced by Pergamum’s rivalry with Alexandria.
The Accident of Innovation
There’s something deeply contingent about this legacy. Parchment’s development apparently resulted from a political embargo, from one king’s jealous attempt to undermine a rival’s library. The innovation that would enable the preservation of countless texts through the medieval period emerged not from careful planning but from necessity imposed by geopolitical competition.
This contingency reminds us that the history of information isn’t a story of smooth progress toward better systems. It’s a history of accidents, rivalries, embargoes, and unintended consequences. If Egypt hadn’t controlled papyrus production, if Ptolemy hadn’t imposed an embargo, if Pergamene craftsmen hadn’t responded with innovation, the material history of Western civilisation would look completely different.
Parchment’s durability proved essential during the centuries following Rome’s fall. Papyrus continued to be used in the Mediterranean world into the early medieval period, but as trade networks fractured and Egyptian imports became unreliable, European scribes depended increasingly on parchment. The technology developed in Pergamum allowed monastic scriptoria to operate independently of long-distance trade, to preserve and copy texts even in periods of political chaos.
The codex format, enabled by parchment, also proved crucial for Christianity’s textual culture. The ease of referencing specific passages made the codex ideal for scripture and theological works that required constant consultation and comparison. The church’s adoption of the codex accelerated its spread and ensured that when the scroll finally gave way to the book, Western literary culture was ready to embrace the new format.
Material Determinism and Cultural Choice
The Pergamum story raises fascinating questions about technological determinism. Did material constraints determine how information was stored and transmitted, or did cultural choices shape material technologies? The answer seems to be both: materials constrained what was possible, but within those constraints, choices mattered.
Parchment enabled the codex, but didn’t require it. For centuries, both formats coexisted. The eventual triumph of the codex reflected not just material advantages but cultural decisions about what made a proper book. Similarly, while parchment was more durable than papyrus, this durability had meaning only because people chose to preserve texts, to copy them before they deteriorated, to value the past enough to invest resources in maintaining continuity with it.
The materials we use to store information shape what gets preserved and what gets lost. Clay tablets survived because fire hardened them. Papyrus scrolls mostly perished because they were fragile. Parchment endured when cared for but could be scraped clean and reused when resources were scarce, leading to the loss of texts deemed less valuable. Today, digital storage promises perfect replication but faces different vulnerabilities: format obsolescence, degradation of storage media, and dependence on functioning technological infrastructure.
Forgetting Pergamum
Perhaps the strangest aspect of Pergamum’s legacy is how thoroughly its own story was forgotten. For centuries, parchment was simply the material books were made from; few remembered that its development centred on one city, arose from one library’s needs. The word parchment derives from pergamena, preserving the connection linguistically even as the history behind it faded from memory.
This forgetting teaches its own lesson about information preservation. We remember dramatic destructions; the burning of Alexandria became legendary. We forget the gradual processes of innovation, the mundane problem-solving that actually shapes how knowledge is transmitted. The spectacular disaster captures imagination; the quiet technical revolution that changes everything gets taken for granted.
Yet recovery is possible. Nineteenth-century excavations at Pergamum revealed the library’s foundations, confirming and complicating ancient accounts. Scholars can now walk through spaces where ancient librarians once shelved scrolls, where craftsmen perfected parchment production, and where Crates of Mallos organized what he hoped would be a collection to rival Alexandria’s.
The Eternal Second Place
The Library of Pergamum occupies a curious position in cultural memory: eternally second to Alexandria, remembered more for what it enabled than for what it achieved. This seems fitting. Second-place institutions often drive innovation more than dominant ones do. Leaders defend their position; challengers must innovate to compete. Alexandria’s monopoly on papyrus forced Pergamum to innovate; that innovation outlasted both libraries.
There’s consolation in this for institutions that can’t be first or largest. The Library of Pergamum never exceeded Alexandria in holdings or surpassed it in scholarly reputation. Yet its contribution to the preservation of knowledge was, in practical terms, more consequential than Alexandria’s. Not because it collected better or organized more effectively, but because it solved a material problem in a way that enabled preservation across a millennium of turbulence.
When we hold a physical book, we’re experiencing technology whose foundations were laid in Pergamum’s rivalry with Alexandria. When we flip through pages to find a specific passage, we’re using an interface that parchment codices made possible. The Library of Pergamum is gone, but every time we open a book, we’re inheriting the solution its craftsmen developed to an embargo imposed twenty-two centuries ago.
In our next article, we’ll explore what happened to classical learning and book production when the Roman Empire collapsed, examining how monastic libraries became the bridges carrying ancient knowledge across the chasm of political fragmentation—using, of course, the parchment codices that Pergamum’s innovation made possible.
