The Middle Ages, an interesting period spanning from the 5th to the 15th century, continue to arouse our curiosity and amazement. Although often perceived as a dark era, this time is full of unusual daily practices and surprising innovations that challenge our preconceived ideas. From hygiene customs to popular beliefs, including technical advances, let’s dive into the mysteries of medieval daily life that still surprise us today.
Sommaire
Hygiene customs: between myths and realities
Contrary to the common belief that people in the Middle Ages lived in filth, hygiene practices were much more elaborate than one might think. Public baths, called étuves, were common in medieval towns. These establishments, true social centers, welcomed men and women for bathing and relaxation sessions. In 1292, Paris had no fewer than 26 public bath establishments, demonstrating the importance given to bodily hygiene.
However, some practices may seem strange to us today. For example, the use of vinegar as a disinfectant and deodorant was common. People rubbed their armpits and feet with vinegar to eliminate body odors. This method, although surprising, proved effective thanks to the antibacterial properties of vinegar.
Another fascinating aspect of medieval hygiene concerns teeth. While we often imagine toothless and foul-smelling mouths, people in the Middle Ages took care of their teeth. They used chewing sticks, primitive toothbrushes made from aromatic wood twigs such as rosemary or thyme. These sticks cleaned the teeth while leaving fresh breath.
Here is a summary table of common hygiene practices in the Middle Ages:
| Practice | Description | Benefit |
|---|---|---|
| Public baths | Bathing and relaxation establishments | Body hygiene and socialization |
| Use of vinegar | Application on the skin as a disinfectant | Elimination of odors and bacteria |
| Chewing sticks | Aromatic wood twigs to clean teeth | Dental hygiene and fresh breath |
Popular beliefs and superstitions in daily life
Daily life in the Middle Ages was deeply influenced by a mix of religious beliefs, superstitions, and folklore. These beliefs, often based on a limited understanding of the natural world, guided people’s actions and decisions in ways surprising to us today.
One of the most widespread beliefs concerned auspicious and inauspicious days. People firmly believed that some days were more favorable than others for undertaking various activities. For example, Friday was considered an unlucky day to get married or start a journey. This superstition was so ingrained that even kings and nobles planned their activities according to these beliefs.
Amulets and talismans also played an essential role in daily life. They were believed to protect against diseases, the evil eye, and malevolent influences. Objects as varied as animal teeth, precious stones, or pieces of parchment bearing sacred inscriptions were worn as protection. In 1365, King Charles V of France owned a collection of more than 300 amulets and talismans, illustrating the importance given to these objects even in the highest spheres of society.
Beliefs related to food were particularly fascinating. The theory of humors, inherited from Antiquity, greatly influenced eating habits. According to this theory, each food was classified according to its qualities (hot, cold, dry, moist) and had to be consumed according to each person’s temperament to maintain the balance of bodily humors. Consequently, a person considered to have a “hot” temperament had to favor “cold” foods to stay healthy.
Here is a list of the most surprising popular beliefs in the Middle Ages:
- Wearing a belt made of wolf skin protected against bites from rabid dogs
- Eating nuts that resembled body parts could heal the corresponding organs
- Mushrooms grew where lightning had struck the ground
- Pregnant women should not look at the moon for fear of having a sleepwalking child
- Burying an egg in the garden ensured a good harvest

Medieval technical innovations: inventions that changed daily life
Contrary to the image of a stagnant period, the Middle Ages were the scene of many technical innovations that profoundly transformed daily life. These inventions, sometimes little known, laid the foundations of our modern world and continue to surprise us with their ingenuity.
One of the most remarkable innovations was the invention of the mechanical clock in the 13th century. Although rudimentary at first, these clocks revolutionized the perception of time. The first public mechanical clock was installed in Milan in 1335, marking the beginning of a new era where time was no longer dictated only by the sun and church bells. This invention had a profound impact on the organization of work and social life, allowing better planning of daily activities.
In agriculture, the introduction of the horse collar greatly improved the efficiency of field work. This seemingly simple innovation allowed horses to pull heavier loads without choking, thus increasing agricultural productivity. As a journalist passionate about unusual discoveries, I cannot help but be fascinated by the considerable impact of this invention on the daily life of medieval peasants.
The invention of eyeglasses at the end of the 13th century in Italy also marked a turning point. These corrective lenses allowed artisans, scribes, and scholars to extend their active lives, paving the way for a wider dissemination of knowledge. The first glasses were often perched on the nose or held in the hand, far from the comfortable frames we know today.
Here is a chronological list of the main technical innovations of the Middle Ages:
- 7th century: Invention of the water mill
- 9th century: Development of the heavy plow
- 11th century: Appearance of the first windmills in Europe
- 13th century: Invention of the mechanical clock
- 13th century: Creation of the first eyeglasses
- 14th century: Development of gunpowder artillery
- 15th century: Invention of movable type printing by Gutenberg
The medieval legacy in our modern daily life
Although centuries separate us from the Middle Ages, many aspects of this period continue to influence our daily life, often in unsuspected ways. By studying these connections, we understand how much this fascinating era shaped our modern world.
In the culinary field, many medieval practices persist. The use of spices to preserve and enhance the taste of food, a major innovation of the Middle Ages, remains central in our gastronomy. Dishes like gingerbread or mulled wine with spices, popular during the year-end holidays, are direct legacies of medieval recipes.
Medieval games and leisure activities have also left their mark. Chess, introduced to Europe in the 9th century, remains a popular strategy game. Modern sports tournaments, with their complex rules and competitive spirit, have their roots in the jousts and knightly tournaments of the Middle Ages.
In the field of health, some medieval practices have evolved into modern alternative therapies. The use of medicinal plants, widespread in the Middle Ages, is experiencing a resurgence in the form of phytotherapy. Bloodletting, a common medical practice at the time, has evolved into safer techniques like blood donation, which today saves millions of lives.
As a journalist always on the lookout for surprising information, I am constantly amazed by the persistence of certain medieval beliefs in our modern society. For example, the idea that stress can prematurely whiten hair originates from medieval legends about kings whose hair supposedly turned white overnight due to intense emotional shock.
Medieval architecture continues to inspire and attract. The construction techniques developed to erect the Gothic cathedrals are still studied and admired today. The Notre-Dame Cathedral in Paris, whose construction began in 1163, remains one of the most visited monuments in the world, attesting to the lasting appeal of medieval art.
Finally, our modern educational system owes much to medieval universities. The University of Bologna, founded in 1088 and considered the oldest university in the Western world, established a model of higher education that endures to this day. The concepts of university degrees, structured curricula, and academic communities have their roots in these medieval institutions.
