The Library of Alexandria held nearly all the knowledge in the ancient world, but did you ever wonder how they got all of it?
The Library of Alexandria is, even to this day, one of the most well-known libraries in the world. It's most famous for having been burned down, resulting in the loss of nearly all the world's knowledge at the time.
How did they acquire so much of this knowledge? One way was through incoming ships. Any books that were found were copied onto scrolls. The original manuscript was then kept in the library, and the scroll given to the owner!
Just how much was lost during the fire? Historians say it's impossible to tell, since no documentation from the library has survived. However, some estimate that more than 500,000 scrolls were lost forever to history.
