It’s a fascinating idea, and there’s a grain of truth to it. Many works were copied widely before the fire, so fragments could have slipped into monasteries, private collections, or even be part of later manuscripts that never got traced back. Archaeologists have found surprising little pieces of texts that scholars attribute to earlier Alexandrian sources, like fragments of Greek philosophy hidden in medieval manuscripts. Still, the sheer scale of the library’s loss means most of the original works didn’t survive intact. So it’s a mix of myth and possibility—there might be a few hidden relics out there, but the bulk of the treasure was likely lost. It’s one of those quiet mysteries that makes the world of books all the more intriguing.
