Did the burning of the library of Alexandria really set humanity back? I just found out about this and am very interested in it. I'm wondering though what impact this had on humanity and our advancement and knowledge. What kind of knowledge was in this library? I can't help but wonder if anything we don't know today was in the library and is now lost to us. Was it even a fire that burned the library down to begin with? It's all very interesting and now I feel as though I'm going to go down a rabbit hole.
