How dark is medieval medical technology in Europe?

Around 476-1453 AD, it began with the demise of the Western Roman Empire. At that time, there was no boss in Europe who kept his word. Frank, Lumbard, Vandal, East Goth and West Goth ... Small countries are fighting according to their own conditions. If they don't agree with each other, it will be a mess.

People are living in the pain of war, and social and economic development has basically stopped. Only when one has enough to eat and wear warm clothes can one enjoy leisure and develop interest. Obviously, no one has the energy to develop art now. The famous "Crusade" took place during this period. Roman Catholicism launched an expedition against Islam in the name of recovering the holy land in Jerusalem. One word: "kill kill", two words: "bloody" and "cruel". After nearly 2 years of fighting, Jerusalem finally fell into the hands of Muslims, but Byzantium (East Rome) was wrongly destroyed.

The mysterious "knight" was also in this period. Cavalry with formal military training was called knight, which later evolved into honorary title. Three famous knights: hospital, temple and Teutonic. Hospital knights mainly take care of the wounded and pilgrims, which continues to this day. The red cross symbol comes from that era. The Sovereign Military Order of Malta is a successor or member of the United Nations. It can't be found on the map at all. The only territory is the .12 square kilometer building "Malta Palace".

The Templars are only responsible to the Pope, not to the king or local bishops. They are super-rich knights, owning more than 9, properties at the end of the 12th century. Even the king envied the popularity of this tree. One Friday, the French King's Regiment destroyed the Templars, and there was a "Black Friday". In 1939, about 625 AD, Sutton Hoo Cave was discovered, Roman art reached its peak, Gothic art sprouted, vernacular appeared, and Latin classicism, Latin poetry, architecture, sculpture, drama, law, philosophy and education all developed. From these viewpoints, the Middle Ages are actually developing.
