Everyone interested in this story should read Stephen Greenblatt's The Swerve (https://www.pulitzer.org/winners/stephen-greenblatt).
It traces the story of a Renaissance humanist who tracked down and translated the Epicurean philosopher/poet Lucretius' De Rerem Natura, which Greenblatt describes as portraying a strikingly modern way of seeing the world.
In particular Lucretius and the Epicureans denied the existence of supernatural causes, were opposed to religious fear, and posited the ideas of atomism and biological evolution. Of course they're better known for their approach to living life, which Greenblatt shows is more sophisticated than sometimes caricatured, and which he portrays as a breath of fresh air compared to the oppressive moralism and hypocrisy of the Church at the time. (Jefferson and many of the American Founders described themselves as Epicureans.)
He goes on to imply that Epicureanism was influential and widespread in the ancient world but suppressed by the early Church, so that we now know little of it.
Anyone, one of the tantalizing parts of the book is where he describes the carbonized and unreadable Herculaneum scrolls, since they were the private library of a wealthy patron of the Epicureans. I think he thinks being able to read the scrolls will really change our understanding of the ancient world.
And remember: if they hadn't been carbonized, they would have crumbled to dust. That's why we only have the texts that managed to get copied.
