* Ancient Mesopotamia: Dragon-like creatures appear in Sumerian and Babylonian mythology around 3000 BCE. They are often depicted as serpentine beings with wings and are associated with chaos and destruction.
* Ancient Greece: The earliest Greek accounts of dragons date back to the 7th century BCE. They were often associated with the gods and were known for their fierce nature and ability to breathe fire.
* Ancient China: Dragons in Chinese mythology have existed for thousands of years, with the earliest written accounts dating back to the Shang Dynasty (1600-1046 BCE). Chinese dragons are often depicted as benevolent beings associated with good luck and power.
* Medieval Europe: The idea of dragons in European folklore became popular in the Middle Ages. They were often depicted as fierce and dangerous creatures that guarded treasure and terrorized villages.
So, when did dragons "start"? It's impossible to say for sure. However, the evidence suggests that dragon mythology has been around for thousands of years and has evolved and adapted in different cultures.
Ultimately, the "beginning" of dragons is a matter of myth and folklore, rather than historical fact.
