How Were Letters Written in Medieval Times?

Sending a message in the Middle Ages was never as simple as licking a stamp and dropping an envelope into a postbox. It was a physical, tactile, and deeply human process that turned animal skins, crushed wasp galls, and bird feathers into some of the most powerful communication tools of the age.

The Ink: A Chemical Reaction

Medieval ink was not something you bought in a neat plastic bottle. It was a dark, chemically reactive mixture brewed from an unlikely recipe.

The most common writing ink was iron gall ink. This was created from several key ingredients: crushed oak galls, the strange growths formed when gall wasps laid their eggs in oak tissue; iron sulphate, often known as copperas; water, wine, or vinegar; and gum arabic, the hardened sap of acacia trees, which reached Europe through long-distance trade routes.

The chemistry is straightforward: the tannic acid released by the galls reacts with the iron sulphate to produce a deep, purple-black liquid. Scribes might soak, cook, ferment, or mix the ingredients according to different recipes before the ink was ready to use. Fresh from the pot, the ink could appear dark and rich; over centuries, it often oxidised, fading to the characteristic rusty brown seen in many manuscripts today.

The Pen: A Feather’s Hidden Power

The might of the written word rested on the tip of a feather. The scribe’s pen was a quill, most often cut from the primary flight feather of a goose or swan.

Creating a quill required real skill. The feather’s barrel was naturally curved, and the scribe used a small knife to harden, trim, shape, and repeatedly sharpen the nib. The scribe would make a series of precise cuts to carve the nib, then slice a tiny slit up the middle to draw the ink down by capillary action. The quality of the cut, rather than the size of the feather alone, determined how well the pen held and released ink.

How Were Letters Delivered in Medieval Times?

Delivery was personal. A messenger handed the letter directly to the recipient or to their household. There were no letterboxes and no addresses in the modern sense.

Finding someone required local knowledge. Messengers asked along the route. Towns, monasteries, markets, and inns served as information hubs where a traveller could ask: ‘Has Lord Eustace passed through here?’

The Risks of Delivery

Letters could be stolen, lost, or intercepted. Important correspondence was sometimes written in code. At other times, the most sensitive information was memorised by the messenger and never written down.

Wax seals protected letters from casual tampering. Breaking a seal left visible evidence, although determined people could still find ways around it.

Message delivery faces the same problems today: it can be intercepted, read, or even forged. A reliable mail carrier was the solution of the time, and the VeePN service is the solution of today. A VPN offers message encryption so secure that only the recipient can decrypt it.

The Scripts: The Art of the Hand

There was no single medieval handwriting style; the script used depended on purpose, audience, region, training, and budget.

Textura was among the most formal and visually striking scripts, often used for Bibles, liturgical books, and prestigious manuscripts. Each letter was built from separate, carefully placed strokes, with the pen lifted frequently. It was painstakingly slow.

Anglicana, a cursive script developed in thirteenth-century England, was faster. The pen stayed on the page for longer, letters were often joined with flowing strokes, and documents could be produced more quickly. This was a hand associated with legal, administrative, literary, and practical writing.

Then came the Secretary, which developed in the later Middle Ages and became increasingly important in clerical and administrative writing, especially from the fifteenth century onwards. A flowing, joined hand was faster and easier for practical writing than highly formal book scripts, which required more frequent lifting of the quill from the parchment. By the fifteenth century, many forms of practical correspondence used cursive or semi-cursive scripts.

Scribes often held the pen at an angle to exploit the shading a quill nib could produce: the natural variation in stroke thickness that gave the writing its visual texture.

Getting It There: The Long Journey

Once written, the challenge was delivery. There was no public postal service for most of the medieval period.

Important letters were often folded into self-contained packets and sealed with wax, into which the sender pressed a signet ring or seal matrix as a mark of authenticity.

The letter might then be entrusted to a passing merchant, a pilgrim, a servant, or a paid messenger. Traders carried letters by boat across the sea and along overland routes. Royal courts had dedicated couriers; the English monarchy used official messengers for royal business. Wealthy nobles used their own servants as letter-bearers.

Words Only a Few Could Read

Throughout all this—the curing of skins, the brewing of ink, the cutting of quills—loomed a stark reality. Around the year 1500, literacy in much of Europe remained limited, though rates varied by region, gender, class, and by what historians mean by ‘literacy’. One common estimate suggests that perhaps around 10 per cent of men and 1 per cent of women were literate in late medieval Europe, though reading and writing ability did not always go together. Not everyone who could read could write.

Professional scribes and scriveners clustered around churches, courts, and marketplaces, hired by merchants, nobles, and others who lacked the skills to produce their own records. The written word was power, and for centuries, that power was held in the hands of a relatively select few.

The Spirit of a Letter

A medieval letter was never merely a casual text. It was a physical object with its own formal architecture. A typical formal letter could be divided into five parts: a greeting, an opening that secured goodwill, a statement of the situation, a request, and a conclusion.

When it arrived, a letter was not always read silently. It might be read aloud in a great hall, a workshop, a monastery, or a synagogue, turning a private message into a shared performance. The letter was not just a container for information. It was a presence, a voice that travelled on skin, ink, and feather, bringing distant people momentarily into the same room.
