Natalie is joined by Professors Islam Issa and Edith Hall to tell the story of the great library of Alexandria. It was included in Alexander the Great's original design for his city, located in the Nile Delta. Alexandria was to be a city of knowledge.

The founders of the library were ambitious: they wanted nothing less than to collect all the books in the world. They were willing to pay huge sums, but they were also ruthless and unscrupulous. The Ptolemies would write to fellow rulers and wealthy friends and ask to borrow their priceless texts. Then the library would copy the scrolls, and return the copies. Or alternatively they'd just steal them.

Handily, papyrus, the principal reading material of the era, grew in great abundance around Alexandria. So there was plenty of it for those copies. Less fortunately, it's extremely flammable. So in 48 BCE, when Julius Caesar's besieged army set fire to ships in the harbour in order to block the invading fleet, the fire spread and destroyed a significant part of the library.
