Off topic, but phrases like "it is said that the books took six months to burn. We can’t know if this is true." bother me. Of course we can know if that is true. This is like saying "it is said the books, upon burning, all turned into unicorns, sang silly songs, and flew to the moon. We can't know if this is true."

The physics of combustion hasn't changed in the last 2000 years.
