There are some 280 carbonized scrolls and papyrus fragments that have been recovered from a villa in Herculaneum, but up to now they have been unreadable, because they cannot be unrolled without damaging them. There is a video here by Brent Searles of the University of Kentucky on the development of the technology that will hopefully allow these scrolls to be read https://youtu.be/Z_L1oN8y7Bs?feature=shared.Only small parts of the heavily damaged text can be read right now. "It contains the names of a number of Macedonian dynasts and generals of Alexander," Janko said, noting that it also includes "several mentions of Alexander himself." After Alexander the Great died in 323 B.C., his empire fell apart. The text mentions the Macedonian generals Seleucus, who came to rule a large amount of territory in the Middle East, and Cassander, who ruled Greece after Alexander's death.
There is also a paper here by Richard Jenko of the University of Michigan, who has been involved in the decipherment of the texts produced by Searles, on the work done on some of the papyri https://www.academia.edu/78533972/How_t ... um_Papyrus.
