I. What We Know
History and geology
HB: Perhaps I could ask you to start us off by providing some general historical context about the history of the excavations at Herculaneum.
AWH: Well, the real excavation of Herculaneum happens under the Spanish regime of Charles Bourbon (King of Naples and Sicily from 1734-1759). Thatâs the great period of excavation. He took a very strong personal interest in it.
And they just explored everywhere. They started at the theatre but itâs a mining principle: you go down and then you go laterally, and they riddled the site with their tunnelsâabsolutely riddled it. And every now and again they would just hit something really spectacular.
They hit the Villa of Papyri at around 1750. Suddenlyâboom!âstatues are coming out. I think itâs a wonderful historical irony that Charles Bourbon was the inheritor of the biggest collection of ancient statues in Italy: the Farnese collection.
In his mind, the obvious thing was, Letâs find statues! And he was so lucky because, well, where do you find statues? You find them in the theatre, you find them in the public buildings and you find them in very big villas with gardens. And he manages to hit all of them.
Imagine hitting a villa, if we did it today, with a hundred statues of quality. Itâs the most incredible find imaginable. And then, as if that wasnât enough, a unique collection of carbonized papyri. It was the most unbelievable bit of luck.
Given how truly amazing that find is, the odd thing is that people later lost interest in Herculaneum. And there I blame the famous German art historian and archaeologist Johan Joachim Winckelmann, who attacked the excavations.
HB: The way they were being done.
AWH: Yes.
HB: This was after Charles had gone back to Spain, right?
AWH: Yes. Charles had gone back to Spain in 1759 to become King Charles III, leaving his son Ferdinand to succeed him as King of Naples. But Ferdinand is only eight years old when he startsâitâs an incredibly delicate regime.
And Bernardo Tannucci, Ferdinandâs prime minister, is trying to hang onto things when this damn German publishes this blast against Herculaneum. And the next thing you find is that theyâve shifted their interest to Pompeii, about which Winckelmann had very little to say because there was nothing to see when he visited. So Herculaneum sort of goes off the radar in a really interesting way; and yet they had only just begun to discover these amazing things.
HB: Iâd like to talk a little bit about your background and how you became involved with Herculaneum and Pompeii, but first Iâd like to highlight a few misconceptions. Reading your book, Herculaneum: Past and Present, was a particularly stimulating experience for me because so many of my preconceived notions of what Herculaneum I thought the site to be were shown to be false.
For one thing, when I thought of Herculaneum, almost the only thing that I thought was noteworthy was the Villa of Papyri. All I could think about was, We know that so much of ancient literature was lost and this could be a place where thereâs a lot more that we can find, since it hasnât been fully explored yet.
Of course I still feel enormous excitement at the prospect of being able to find lost manuscripts, but Iâve also learned through your book that there are also so many other things there that are extremely captivating.
AWH: I think thatâs exactly what I want to say. The Villa has still a lot to offer, and all the work done recently on the Villa has come up with some really interesting results. But it isnât just papyri that you can get out of Herculaneum.
I myself am particularly interested in the documentary wooden tabletsâlegal documents, where you have the document in triplicate all tied together, inscribed inside and with an ink version on the outside. So far weâve found, I think, eight different bundles of these at Herculaneum. And itâs absolutely certain that if you do more excavation you will find more of them. Theyâre incredibly hard to read, but theyâre much easier to read than the papyri because at least they were flat, not all rolled up.
The papyri are an extraordinary challenge to read, while the level of reward you get out of reading these legal documentsâto me as a Roman historianâis much, much higher than what weâve got out of the papyri. Not that Greek philosophy is of no interestâof course itâs fascinatingâbut here youâve got genuine, deep insights into how Roman business life worked, which is so precious.
Of course from the lawyers we have lots of written comments on how the law ought to be working: they give their own little case studies. But actually to see it in action on the groundâreal people using the Roman legal systemâyou suddenly understand that the Roman legal system matters to ordinary people. They are absolutely engaged with it.
HB: Iâd like to get a deeper understanding of what we have found, how we can interpret these results and the consequent aspects of Roman society that youâve been able to penetrate in a deeper way through these finds, but first Iâd like to dwell a bit longer on some of my misconceptions because I suspect that some other people might have them as well.
As I said, one misconception that I had was that the importance of Herculaneum effectively boiled down to just the Villa of Papyri. And thatâs clearly false.
Another misconception I had concerns what actually happened during the volcanic eruption. I donât know how I picked this up, exactly, but somehow I had this sense that Herculaneum was buried in a wave of mud after Vesuvius erupted.
And at the beginning of your book, you mention that the Cambridge archaeologist Charles Waldstein specifically puts this forward as an explanation of what happens. But it turns out to be completely wrong. And then you go on to talk about the clear and detailed interplay between archaeology and geology while highlighting what we now know actually happened during the eruption.
AWH: Thatâs absolutely right. I mean, one thing that just awes me about engaging in the process of archaeological research is how you need to draw on all disciplines, particularly scientific disciplines. Itâs no good, for someone like me who is a historian by training, to try to understand how volcanic eruption works. You need a volcanologist.
And, fascinatingly, volcanologists have been very engaged with this really well-preserved evidence of a past eruption. Since the early 1980s, our understanding of how the eruption actually happened, the precise dynamics, has been transformed.
Irritatingly, the idea that Herculaneum was overwhelmed with a mud flow remains so ingrained in the literature. Nowadays, most Italians still refer to the rock that covers the site as fangoâmud.
And, I always say, âWell, at least itâs a two syllable word, fango, rather than the much more technical mouthful âconsolidated pyroclastic flowâ.
And then, even more irritatingly perhaps, more technically the rock is called tufo, which in English is frequently mispronounced as âtufaâ, which is particularly problematic because tufa is actually the technical name for another completely different type of rock.
Meanwhile, Americans call tufo âtuffâ, but thatâs difficult for the Brits of courseâwe canât go around calling something âtuffââso thatâs problematic too. All of this contributes, I think, to explain why fangoâmudâsticks in the popular imagination.
HB: But itâs completely wrong.
AWH: Itâs spectacularly wrong. Because what matters is not wetness and slowness, what matters is intense heatâthese really hot gases swirling around, dense with ash. And without the heat you donât get the carbonization of organic materials.
