Materials for strings of medieval onions: flax, hemp and silk

The bow string in the Middle Ages was made mainly from twisted flax or hemp threads, since it was these vegetable fibers that provided the necessary balance of strength and elasticity for propellent weapons of that time. Unlike modern synthetic analogues, medieval craftsmen relied on natural materials, whose properties directly affected the range of the arrow and the durability of the bow itself. The choice of specific raw materials depended on the region, climate and availability of resources, but the processing technology remained similar: the fibers were soaked, dried, scratched and twisted into strong harnesses.

The basis for creating a quality archer's They were long and strong fibers, which after special treatment acquired the ability to withstand multiple cycles of tension and relaxation. The manufacturing process began long before the assembly of the onions themselves, as the preparation of the threads required time and patience. Incorrectly selected raw materials could lead to rapid rupture of the bowstring in combat or loss of elasticity when stored in humid climates.

Medieval sources and archaeological finds indicate that torsion It was passed down from generation to generation, overgrown with secrets and nuances known only to a narrow circle of masters. The quality of the final product determined not only the effectiveness of the weapon, but also the life of the owner, so the choice of materials was approached with extreme care. Even in the face of scarcity, warriors have tried not to skimp on this critical element, knowing the consequences of using low-quality substitutes.

Linen and hemp threads: the basis of medieval strings

The most common material for the manufacture of strings in Europe during the Middle Ages was flax and hemp fibers. These crops were grown everywhere, and the technology of their processing was well known to every peasant. Linen thread It was valued for its smoothness and relative resistance to abrasion, which allowed the bowstring to maintain integrity for a long time with frequent use. Hemp, in turn, was more rough, but had outstanding tensile strength, which made it ideal for powerful battle bows.

The raw material preparation process involved soaking the stems in water to separate the fibers from the fire, after which they were dried and combed with combs. The resulting fibers were bound in bundles and twisted into threads of the necessary thickness. To increase the strength of the master often used the method of twisting several thinner threads into one composite. Hemp string It required more careful treatment to remove excessive stiffness that could damage the notches at the ends of the bow.

⚠️ Attention: Natural plant fibers are extremely sensitive to humidity. Wet linen or hemp bowstring stretches and loses elasticity, which requires mandatory drying and re-washing before use.

An important stage of production was the sculpting of ready-made harnesses. For this purpose, beeswax was used, mixed with various resins or fats. This treatment protected the fibers from moisture, dirt and mechanical damage, and also prevented the filaments from unwinding under load. Waxy surface Reduced friction on the archer's fingers and arrow pole, providing a cleaner and more accurate shot.

Silk and wool: premium materials for elite weapons

Silk was often used to make bow strings of high-class bows intended for the nobility or professional warriors. This material had exceptional strength with a minimum diameter of the thread, which allowed to create compact and powerful strings. Silk string less stretched under load compared to plant counterparts, providing a higher initial speed of the arrow.

Wool also found its application, although less often, mainly in mixed weavings or for less powerful hunting bows. The main advantage of wool fibers was their ability to maintain elasticity at low temperatures when flax became brittle. However, the wool wore out more quickly and required frequent replacement, making it less popular for military use.

The technology of working with silk required special skills, since slippery threads had to be twisted at a certain angle so that they did not move. Multilayer weaving was often used, where the inner core was made up of coarser threads, and the outer shell was the thinnest silk. Elite weapons This string was considered a matter of pride and was often inherited.

The Secrets of Silk Processing

The subtlety of processing silk was the use of special adhesives based on fish bladder or egg white, which were applied between the layers of threads. This created a monolithic structure that, after drying, became harder than the thread itself.

Use of skin and tendons in the design of strings

Although plant and silk threads dominated, some regions and cultures actively used animal skin and tendons. The raw-skin string was characteristic of some types of composite bows, especially in the steppe regions and in the East. Leather loop It had a high resistance to abrasion and was not afraid of moisture, which was critically important in the conditions of hikes and long transitions.

Tendons, especially the dorsal tendons of large animals, were used to create composite materials. They were dried, ground into fibers and glued onto a base, creating a layer that works for stretching. In the context of strings, tendons were often woven into the main structure to strengthen critical nodes. So. composite It allowed the load to be distributed more evenly.

The main disadvantage of animal materials was their sensitivity to temperature and humidity changes. The skin could sulphur in the cold or, conversely, too much stretched in the heat. Therefore, the care of such strings required constant monitoring and use of special fat lubricants that penetrated the structure of the material, maintaining its elasticity.

Technology of torsion and weaving of medieval strings

The process of creating a string was time-consuming and required the use of special devices. The main tool was a torsion machine, which allowed you to set the threads the necessary direction and degree of twisting. Right guy. It provided self-tightening of the structure under load, preventing entanglement at the most inopportune moment.

Masters used different weaving schemes, but the most common was the method in which several strands were twisted into one thick thread, which then formed the main working part. The ends of the string, where loops were formed for wearing onion horns, were often braided with additional threads or strengthened with leather linings. Weaving technique It affects the distribution of voltage throughout the length.

• 🧵 Fiber preparation: soaking, drying and combing raw materials to remove short and damaged areas.
• 🌀 Twisting primary threads: creating basic harnesses using a spindle or a simple machine.
• 🔗 Base formation: connection of several primary threads into one composite string with observance of the direction of the twist.
• 🛡️ Finishing: waxing, weaving ends and checking for a break with a gradual increase in load.

An important aspect was the creation of loops. They were not to be too tight to not clamping the horns of the bow, but also not too loose to prevent the bowstring from jumping off. Nodes and connections They were performed to minimize thickening that could interfere with the movement of the boom or create stress points.

Comparative characteristics of materials for strings

The choice of material for strings has always represented a compromise between strength, elasticity, accessibility and resistance to external factors. Different materials had unique characteristics that made them preferable in some conditions and unsuitable in others. Understanding these differences allowed archers to tailor their weapons to specific tasks.

Below is a table comparing the main properties of materials used in the Middle Ages. The data are based on historical reconstructions and properties of natural materials.

Materials	Threatness	Moisture resistance	Elasticity	Cost
Len	Medium	Low (requires impregnation)	Tall.	Low.
Cannabis	Tall.	Medium	Medium	Low.
Silk	Very high.	Tall.	Low (hard)	Tall.
Skin (raw)	Medium	Tall.	Low (stretched)	Medium

When analyzing the data, it can be seen that silk It won in strength characteristics, but its high cost made it inaccessible for mass use. Cannabis It was the middle ground for mass armament, combining availability and reliability. Flax was used where lightness and cheapness were required, but with mandatory processing.

Care, storage and replacement of medieval strings

The service life of the string depended on the intensity of use and operating conditions. In the field, archers always had spare threads or ready-made strings. Regular examination It allowed to detect the scuffling and thinning of the fibers before they led to rupture. Particular attention was paid to the places of attachment of hinges and areas in contact with the fingers.

Storing onions with the bowstring removed was a mandatory rule for composite bows, but for simple wooden bows it extended the life of the equipment. The string was removed to relieve stress from the fibers, preventing their premature aging. Proper storage in a dry place protected the material from decay and mold.

⚠️ Note: It is forbidden to store the bowstring in a rolled-up state or under load. This leads to the deformation of turns and loss of the material's performance.

When signs of wear were found, the bowstring was either repaired, weaving new sections, or completely replaced. The replacement technology required care so as not to damage the horns of the bow when the new string is stretched. Often special devices for tension were used to safely carry out this procedure.

Frequently Asked Questions (FAQ)

Could horse hair be used for strings in the Middle Ages?

Horse hair was sometimes used as auxiliary material or for weaving very thin strings for small bows, but its strength was insufficient for powerful battle bows. The main materials remained plant fibers and silk.

How often did you need to change the bowstring on the battle bow?

The frequency of replacement depended on the material and the conditions of use. Linen string with active use could be changed every few days or weeks, while high-quality silk or hemp with good impregnation served for months. In combat conditions, spare strings were always worn.

Why was the silk string considered better than the linen string?

Silk had a higher strength-to-weight ratio and was less stretched under load, which ensured a more stable bow fight. In addition, silk absorbed less moisture, retaining its properties in wet weather, when flax could significantly lose its effectiveness.

Did metal elements be used in the design of the string?

In its pure form, metal strings were not used in the Middle Ages due to the lack of technologies for the production of thin and durable wire, as well as due to the large weight. Metal parts could only be used as fittings or decorations at the ends of the string, but not as a working element.
