Very exciting. There are many ancient works which we know by name but which have never been found. It would be a great treat to find a play by Sophocles or a book by Aristotle. Or perhaps even something totally unsuspected. This is money well spent.
Any one consider possibly writings regarding Christ or His followers. Talk about shaking things up a bit.
All of Aristotle's 'popular' works (mainly the Dialogues) have been lost and are known only through references. It's an irony of history that what we have are all his unpublished treatises but none of the actual material widely read by the ancient world. I would bet money that his popular works will be found at the Villa of the Papyri, because no Roman library would've been complete without them. How exciting!
BTW, his foremost student Theophrastus was considered by the ancients to rival Aristotle and Plato in the breadth and novelty of his writings. None of his major works have survived to the present but in fragments and finding any of them would be no less exciting.
PS. Aristotle himself so admired Theophrastus' writing skill that he gave him that nickname, which means "divine speaker."
Absolutely one of the most exciting digs in recent history--and thank God it comes now, when we have the technology to decipher the charred scrolls. Any earlier and they might have been damaged or scrapped.
Now if they could just find the Alexandria library...
