Medieval Books: A Fascinating Journey to the Heart of Ancient Knowledge

Nowadays, having a book in your hands is an everyday act. You can find it in any bookstore, library or even the supermarket. But have you ever stopped to think about how different this common object was centuries ago, especially during the Middle Ages? At that time, a book was not simply an object, but a true work of art, incredibly difficult and expensive to produce, reserved for a privileged few. Join us on this journey to discover how books were made and what they represented in the Middle Ages. To check the current offer, you can explore the collection of medieval books.

The Papyri: The Precursor of Medieval Codices

Before the age of parchment and printing, papyrus was the primary medium for writing in the ancient world. Although its use decreased in the Middle Ages, it is essential to understand its role as a precursor. Papyri consisted of several sheets of this material, made from the papyrus plant, which were written on and then glued together along the edges, until forming a more or less long strip that was kept rolled up. These scrolls, known as volumes, were the predominant form of book in civilizations such as the Egyptian, Greek and Roman.

Consulting a papyrus scroll was a laborious process. To read, you had to unroll it with one hand and roll it up with the other, making it difficult to find specific passages or take notes. However, with the consolidation of Christianity, especially from the 4th century onwards, the use of a new form of book spread: the codex, composed of sewn sheets. The advantages of this new arrangement of the texts were evident, especially when it was necessary to constantly consult a text, such as the Bible or law codes. This innovation marked the beginning of what we recognize today as a book.

The Parchment: The Skin that Kept Knowledge

With the appearance of the codex, the use of parchment as the main material for making the sheets was imposed, progressively replacing papyrus. The scroll takes its name from the ancient Hellenistic city of Pergamum, in Asia Minor. A legend transmitted by Pliny the Elder tells us that it was there where it was invented, forced by the need for a new desktop support after Egypt, monopolizer of papyrus, had interrupted its exports to that kingdom in the 2nd century BC. Although its use became popular in the Middle Ages, the manufacture of this material was a long and meticulous process that could take weeks.

How was Parchment Made? A Laborious and Expensive Art

The making of parchment was a combination of chemical, mechanical and manual techniques, and its phases hardly changed from classical antiquity to the Renaissance. It was a laborious art that required great skill and patience. Imagine the following steps:

• Collection and Conservation: First, the skin of the animal (sheep, goats or calves) was obtained, which had to be in optimal condition, without tears or imperfections. Once skinned, it was cleaned of remains of meat and blood, and salted to prevent decomposition during storage or transportation.
• Slamming and Liming: The salted skin was soaked in alkaline lime baths for several days, a process known as “liming.” This loosened the hair and separated the dermal layers. The skin was then carefully scraped with a curved knife, called a lunellum, to remove hair and subcutaneous tissue. This step was crucial to obtain a smooth and uniform surface.
• Tightening and Drying: Once cleaned, the leather was stretched over a wooden frame, using string or hooks to apply constant tension while it dried. This stage was vital, since irregular tension could deform or tear the skin, compromising the quality of the future parchment. Slow drying and under tension contributed to the durability of the material.
• Final Scraping and Smoothing: During drying, a second finer scraping was performed to uniform thickness and improve texture, often with thin blades or pumice stone. Finally, the surface was polished with chalk and flour or a smooth stone, leaving it ready for writing. This final polish was what gave the parchment its characteristic soft feel and its ability to absorb ink without smudging.

Parchment was a living material, with a rougher and darker hair side, and a smoother and lighter flesh side, preferred by copyists. Their sensitivity to humidity and temperature meant that medieval codices needed thick covers and closures to keep the sheets in place and protect them from warping. It was such an expensive material that up to 300 skins could be needed for a single large-format manuscript, underscoring the immense value of each medieval book.

For this reason, parchment was often reused: ancient texts were scraped or washed to write on, giving rise to “palimpsests.” These invaluable sources have allowed modern scholars, thanks to technologies such as multispectral photography, to recover lost classical texts, revealing hidden layers of knowledge that would otherwise have been lost forever. The existence of palimpsests is a direct testimony to the value and scarcity of parchment in the Middle Ages.

Artisan Creation: From Pens to Illuminations

Once the parchment was ready, the real magic began: the writing and the decoration. The making of a book was a unique artisanal task, requiring enormous time and effort from multiple specialists. Each medieval manuscript was written on loose sheets that were later assembled to be bound, and normally the copyist wrote resting the sheets on his knees and outdoors, in the monastery cloister, taking advantage of daylight.

Medieval Copyist's Tools and Inks

• Feathers: Ballpoint pens did not exist, so bird feathers were used, mainly goose or swan, for their robustness and flexibility. These feathers were softened in water, dried and then hardened with hot sand before being cut and sharpened for writing. The tip of the pen was bevel-cut to allow for fine and thick strokes, essential for medieval calligraphy.
• Inks: Black ink, the most common, was made by dissolving charcoal (or soot) with other ingredients such as gum arabic (to adhere to the parchment) and water. For the drawings and elaborate miniatures, colored inks were created from a vast range of vegetables and minerals, each with its own preparation process. For example, blue was obtained from lapis lazuli or indigo, red from cinnabar or cochineal, and green from malachite or verdigris.

The Writing and Illumination Process: A Detailed Art

Writing had to be clear and elegant, and making mistakes was a big problem, since there was no such thing as correction fluid. The only solution was to carefully scrape the parchment with a razor to remove the error and write over it again, a process that required great skill to avoid damaging the delicate support.

To beautify reading and make the texts more attractive, books often included colorful drawings and elaborate capital letters, known as miniatures or illuminations. This art of lighting was a discipline in itself, carried out by specialized artists, the illuminators. To do this, vibrantly colored inks and often precious metals such as gold and silver were used.

The gilding process involved first making a detailed sketch of the design. Then, an adherent substance was applied, such as a mixture of plaster and animal glue (known as bowl), on which gold leaf, an extremely thin layer of this precious metal, was placed. Once adhered, the gold was burnished to give it a deep shine. The other colors were applied starting with the softest tones and then the darkest, building layers to give depth and detail to the illustration. Each miniature was a small work of art that complemented and enriched the text.

The Binding: Protection, Aesthetics and Durability

Finally, once all the pages were written and illuminated, they had to be sewn and attached to a cover that would protect the interior from the passage of time and use. Binding was a crucial process that ensured the durability and preservation of the manuscript. The covers, often made of noble woods such as beech, elm or oak for liturgical books or books of great value, could be richly decorated with reliefs of ivory, chiseled silver, gold and inlaid with precious stones, turning the book into an object of luxury and prestige. The most common manuscripts were covered in leather, which could be embossed or chiseled with decorative motifs.

This entire process, from skin preparation to final binding, could easily take one or two years, and sometimes even longer for large works or highly detailed lighting! This investment of time and human and material resources explains the very high value of each medieval book.

Monasteries and Universities: The Centers of Medieval Knowledge

During the Early Middle Ages, many monasteries were intensely dedicated to the preservation and copying of books. The monks specialized in the different parts of the process in places known as scriptoria (desks), from the creation of the parchment to the writing of the texts and their illustration. Dozens of people could participate in the creation of a single book, working in an atmosphere of silence and dedication. These monasteries acted as true beacons of knowledge in a time of great instability.

Although monks played a crucial role in preserving religious texts and some works of classical antiquity, their primary goal was not always cultural preservation for its own sake, but rather understanding and disseminating religious texts, especially the Bible and the writings of the Church Fathers. In fact, very old works were sometimes destroyed to reuse the parchment, creating the aforementioned palimpsests, which demonstrates the primacy of necessity over conservation at certain times.

However, as far as the 12th and 13th centuries are concerned, the most relevant thing is that it is precisely between both centuries when the monastic monopoly on the production of books comes to an end. In the last three centuries of the medieval period, it was not monks, but lay professionals, who were responsible for the production of codices. The main cause of this change is the birth and rise of universities in European cities, such as Paris, Bologna or Oxford.

University students and professors needed books in large quantities and on various subjects (theology, law, medicine, philosophy), which generated unprecedented demand. This university demand gave rise to a flourishing book trade in the 13th century, which passed into the hands of professional urban workshops. These workshops, often organized in guilds, were capable of more massive and serial production, feeding the needs not only of universities, but also of an emerging wealthy lay class, increasingly cultured and with greater purchasing power, who desired to own books for personal study or simple pleasure.

The Book and Medieval Society: An Object of Luxury and Power

Due to their complex production and the high cost of materials, especially parchment, books were incredibly expensive. Only the richest and most powerful could aspire to own a few. If in the Middle Ages you had had more than ten books in your home, not only would you have been considered a very wise person, but you would have been incredibly envied, perceived as someone very wealthy and of great social influence. Books were symbols of status, wealth and access to knowledge.

From the 14th century onwards, with the rise of cities and the expansion of trade, paper, which reached Europe through Arab culture (which had learned it from China), began to spread. This new material was a much cheaper and faster alternative to manufacture than parchment, which contributed to greater production and dissemination of texts, although parchment continued to be reserved for luxury editions and documents of great legal or religious importance.

Each medieval manuscript was written on loose sheets that were later assembled to be bound, and normally the copyist wrote resting the sheets on his knees and outdoors, in the cloister of the monastery, taking advantage of the daylight. This image evokes the patience and dedication necessary for each copy.

The books were very different from each other, not only in content, but also in the way the text was presented or the decorative style; they fundamentally depended on the recipient of the work. A book for a king or high clergyman would be richly illuminated and bound, while a text for a student might be more austere and functional.

The cause of the change in book production is in the birth of universities; Students need books, and university demand will give rise to a book trade in the 13th century that will pass into the hands of professional urban workshops, authors of massive and serial production that will feed the needs not only of this, but also of an emerging wealthy secular class that is increasingly more cultured.

The book in the Middle Ages itself is a handmade object that requires high qualification and the help of several specialists and different materials: parchment or paper and ink to write it, pigments of different colors and gold leaf to decorate it, rope, wood, thread, leather and metal clasps to bind it. Each of these elements contributed to the uniqueness and value of each manuscript.

The Dawn of a New Age: The Impact of the Printing Press

Parchment remained in use well into the 16th century, especially for official and highly prestigious documents. However, the invention of the movable type printing press by Johannes Gutenberg around 1440-1453 in Mainz, Germany, marked the end of the medieval manuscript era and the beginning of mass book production. This technique spread quickly, reaching Italy in 1465 and then throughout Europe.

With the printing press, the book ceased to be a unique and artisanal object, reproduced on individual demand. The copying process was drastically accelerated, which reduced production costs and, in turn, noticeably increased the spread of books. By 1510, most of the books made in Europe were already printed, that is, made on a printing press.

This marked a cultural revolution, as knowledge, previously restricted and controlled primarily by the Catholic Church and monks, was able to expand to a much wider audience. Literacy received an unprecedented boost, and the printing press became a powerful tool that challenged the absolute powers (monarchies and church), which for centuries had monopolized access to knowledge. The spread of ideas, religious reform, and scientific advancement were greatly facilitated by this invention.

An Enduring Legacy: The Importance of Medieval Books

Medieval books are much more than simple texts; They are fragments of history that last. Its resistance to wear, together with the protection of the bindings and the controlled conditions of monastic scriptoria archives and archives, have allowed thousands of manuscripts to survive wars, catastrophes and the relentless passage of time. Every fold, every imperfection in the texture of the parchment, every stroke of ink, tells us about the time, the material and the dedication invested in preserving and transmitting the knowledge of an era. They are an incalculable testimony of human history, the evolution of thought and artisanal mastery.

Studying these manuscripts not only allows us to understand their textual content, which ranges from theology and philosophy to literature, history and science, but also to understand the production methods, artistic techniques and daily lives of the copyists, illuminators and binders who made them. They offer us a unique window into the mentality, beliefs and aspirations of medieval society. Its study is essential for anyone interested in the history, culture and evolution of the book as an object and as a vehicle of knowledge.
