Medieval technology


Medieval technology is the technology used in medieval Europe under Christian rule. After the Renaissance of the 12th century, medieval Europe saw a radical change in the rate of new inventions, innovations in the ways of managing traditional means of production, and economic growth. The period saw major technological advances, including the adoption of gunpowder, the invention of vertical windmills, spectacles, mechanical clocks, and greatly improved water mills, building techniques, and agriculture in general.
The development of water mills from their ancient origins was impressive, and extended from agriculture to sawmills both for timber and stone. By the time of the Domesday Book, most large villages had turnable mills, around 6,500 in England alone. Water power was also widely used in mining for raising ore from shafts, crushing ore, and even powering bellows.
Many European technical advancements from the 12th to 14th centuries were either built on long-established techniques in medieval Europe, originating from Roman and Byzantine antecedents, or adapted from cross-cultural exchanges through trading networks with the Islamic world, China, and India. Often, the revolutionary aspect lay not in the act of invention itself, but in its technological refinement and application to political and economic power. Though gunpowder along with other weapons had been started by Chinese, it was the Europeans who developed and perfected its military potential, precipitating European expansion and eventual imperialism in the Modern Era.
Also significant in this respect were advances in maritime technology. Advances in shipbuilding included the multi-masted ships with lateen sails, the sternpost-mounted rudder and the frame-led hull construction. Along with new navigational techniques such as the dry compass, the Jacob's staff and the astrolabe, these allowed economic and military control of the seas adjacent to Europe and enabled the global navigational achievements of the dawning Age of Exploration.
At the turn to the Renaissance, Gutenberg's invention of mechanical printing made possible a dissemination of knowledge to a wider population, that would not only lead to a gradually more egalitarian society, but one more able to dominate other cultures, drawing from a vast reserve of knowledge and experience. The technical drawings of late-medieval artist-engineers Guido da Vigevano and Villard de Honnecourt can be viewed as forerunners of later Renaissance artist-engineers such as Taccola or Leonardo da Vinci.

Civil technologies

The following is a list of some important medieval technologies. The approximate date or first mention of a technology in medieval Europe is given. Technologies were often a matter of cultural exchange and date and place of first inventions are not listed here.

Agriculture

Carruca
A type of heavy wheeled plough commonly found in Northern Europe. The device consisted of four major parts. The first part was a coulter at the bottom of the plough. This knife was used to vertically cut into the top sod to allow for the plowshare to work. The plowshare was the second pair of knives which cut the sod horizontally, detaching it from the ground below. The third part was the moldboard, which curled the sod outward. The fourth part of the device was the team of eight oxen guided by the farmer. This type of plough eliminated the need for cross-plowing by turning over the furrow instead of merely pushing it outward. This type of wheeled plough made seed placement more consistent throughout the farm as the blade could be locked in at a certain level relative to the wheels. A disadvantage to this type of plough was its poor maneuverability. Since this equipment was large and led by a small herd of oxen, turning the plough was difficult and time-consuming. This caused many farmers to turn away from traditional square fields and adopt a longer, more rectangular field to ensure maximum efficiency.
Ard
While ploughs have been used since ancient times, during the medieval period plough technology improved rapidly. The medieval plough, constructed from wooden beams, could be yoked to either humans or a team of oxen and pulled through any type of terrain. This allowed for faster clearing of forest lands for agriculture in parts of Northern Europe where the soil contained rocks and dense tree roots. With more food being produced, more people were able to live in these areas.
Horse collar
Once oxen started to be replaced by horses on farms and in fields, the yoke became obsolete due to its shape not working well with a horses' posture. The first design for a horse collar was a throat-and-girth-harness. These types of harnesses were unreliable though due to them not being sufficiently set in place. The loose straps were prone to slipping and shifting positions as the horse was working and often caused asphyxiation. Around the eighth century, the introduction of the rigid collar eliminated the problem of choking. The rigid collar was "placed over the horses head and rested on its shoulders. This permitted unobstructed breathing and placed the weight of the plow or wagon where the horse could best support it."
Horseshoes
While horses are already able to travel on all terrain without a protective covering on the hooves, horseshoes allowed horses to travel faster along the more difficult terrains. The practice of shoeing horses was initially practiced in the Roman Empire but lost popularity throughout the Middle Ages until around the 11th century. Although horses in the southern lands could easily work while on the softer soil, the rocky soil of the north proved to be damaging to the horses' hooves. Since the north was the problematic area, this is where shoeing horses first became popular. The introduction of gravel roadways was also cause for the popularity of horseshoeing. The loads a shoed horse could take on these roads were significantly higher than one that was barefoot. By the 14th century, not only did horses have shoes, but many farmers were shoeing oxen and donkeys in order to help prolong the life of their hooves. The size and weight of the horseshoe changed significantly over the course of the Middle Ages. In the 10th century, horseshoes were secured by six nails and weighed around one-quarter of a pound, but throughout the years, the shoes grew larger and by the 14th century, the shoes were being secured with eight nails and weighed nearly half a pound.
Crop rotation
Two-field system
In this simpler form of crop rotation, one field would grow a crop while the other was allowed to lie fallow. The second field would be used to feed livestock and regain lost nutrients through being fertilized by their waste. Every year, the two fields would switch in order to ensure fields did not become nutrient deficient. In the 11th century, this system was introduced into Sweden and spread to become the most popular form of farming. The system of crop rotation is still used today by many farmers, who will grow corn one year in a field and will then grow beans or other legumes in the field the next year.
Three-field system
While the two-field system was used by medieval farmers, a different system was also being developed at the same time. In a three-field system, one field holds a spring crop, such as barley or oats, another field holds a winter crop, such as wheat or rye, and the third field is an off-field that is left alone to grow and is used to help feed livestock. By rotating the three crops to a new part of the land after each year, the off-field regains some of the nutrients lost during the growing of the two crops. This system increases agricultural productivity over the two-field system by only having one-third of the land unused instead of one half. Many scholars believe it helped increase yields by up to 50%.
Wine press
During the medieval period the wine press had been constantly evolving into a more modern and efficient machine that would give wine makers more wine with less work. This device was the first practical means of pressing wine on a flat surface. The wine press was made of a giant wooden basket that was bound together by wooden or metal rings. At the top of the basket was a large disc that would depress the contents in the basket, crushing the grapes and producing the juice to be fermented.
The wine press was an expensive piece of machinery that only the wealthy could afford, and grape stomping was still often used as a less expensive alternative. While white wines required the use of a wine press in order to preserve the color of the wine by removing the juices quickly from the skin, red wine did not need to be pressed until the end of the juice removal process since the color did not matter. Many red wine winemakers used their feet to smash the grapes then used a press to remove any juice that remained in the grape skins.
Qanat
Ancient and medieval civilizations needed and used water to grow the human population as well as to partake in daily activities. One of the ways that ancient and medieval people gained access to water was through qanats, which were a water duct system that would bring water from an underground source or river source to villages or cities. A qanat is a tunnel that is just big enough that a single digger could travel through the tunnel and find the source of water as well as allow for water to travel through the duct system to farm land or villages for irrigation or drinking purposes. These tunnels had a gradual slope which used gravity to pull the water from either an aquifer or a water well. This system was originally found in middle eastern areas and is still used today in places where surface water is hard to find. Qanats were very helpful in not losing water while being transported as well. The most famous water duct system was the Roman aqueduct system, and medieval inventors used the aqueduct system as a blueprint for getting water to villages more quickly and easily than diverting rivers. After aqueducts and qanats much other water based technology was created and used in medieval periods including water mills, dams, wells and other such technology for easy access to water.
