The
British Museum's 2013 show of artefacts from the Roman cities of
Pompeii and Herculaneum, buried in ash during an explosive eruption of
Mount Vesuvius, was a sell-out. But could even greater treasures -
including lost works of classical literature - still lie underground?
For centuries scholars have been hunting for the lost works
of ancient Greek and Latin literature. In the Renaissance, books were
found in monastic libraries. In the late 19th Century papyrus scrolls
were found in the sands of Egypt. But only in Herculaneum in southern
Italy has an entire library from the ancient Mediterranean been
discovered in situ.
On the eve of the catastrophe in 79 AD, Herculaneum was a
chic resort town on the Bay of Naples, where many of Rome's top families
went to rest and recuperate during the hot Italian summers.
It was also a place where Rome's richest engaged in a bit of
cultural one-upmanship - none more so than Lucius Calpurnius Piso
Caesoninus, a politician and father-in-law of Julius Caesar.
In Herculaneum, Piso built a seaside villa on a palatial
scale - the width of its beach frontage alone exceeds 220m (721ft). When
it was excavated in the middle of the 18th Century, it was found to
hold more than 80 bronze and marble statues of the highest quality,
including one of Pan having sex with a goat.
When he came to plan his own exercise in cultural showing
off, J Paul Getty chose to copy Piso's villa for his own Getty museum in
Malibu, California.
Piso's grand villa, which has come to be known as the Villa of
the Papyri, also contains the only library to have survived from the
classical world. It is a relatively small collection, some 2,000
scrolls, which the eruption nearly destroyed and yet preserved at the
same time.
A blast of furnace-like gas from the volcano at 400C (752F)
carbonised the papyrus scrolls, before the town was buried in a fine
volcanic ash which later cooled and solidified into rock.
When excavators and treasure hunters set about exploring the
villa in the 18th Century, they mistook the scrolls for lumps of
charcoal and burnt logs. Some were used as torches or thrown on to the
fire.
But once it was realised what they were - possibly because of the
umbilicus, the stick at the centre of the scrolls - the challenge was to find a way to open them.
Some scrolls were simply hacked apart with a butcher's knife -
with predictable and lamentable results. Later a conservator from the
Vatican, Father Antonio Piaggio (1713-1796), devised a machine to
delicately open the scrolls. But it was slow work - the first one took
around four years to unroll. And the scrolls tended to go to pieces.
The fragments pulled off by Piaggio's machine were fragile
and hard to read. "They are as black as burnt newspaper," says Dirk
Obbink, a lecturer in Papyrology at Oxford University, who has been
working on the Herculaneum papyri since 1983.
Under normal light the charred paper looks "a shiny black" says Obbink, while "the ink is a dull black and sort of iridesces".
Reading it is "not very pleasant", he adds. In fact, when
Obbink first began working on them in the 1980s the difficulty of the
fragments was a shock. On some pieces, the eye can make out nothing. On
others, by working with microscopes and continually moving the fragments
to catch the light in different ways, some few letters can be made out.
Meanwhile, the fragments fall apart. "At the end of the day
there would be black dust on the table - the black dust of the scroll
powdering away. I didn't even want to breathe."
A section of On the Good King by Philodemus of Gadara, in normal light...
This all began to change 15 years ago.
In 1999, scientists from Brigham Young University in the US
examined the papyrus using infrared light. Deep in the infrared range,
at a wavelength of 700-900 nanometres, it was possible to achieve a good
contrast between the paper and the ink. Letters began to jump out of
the ancient papyrus. Instead of black ink on black paper, it was now
possible to see black lines on a pale grey background.
Scholars' ability to reassemble the texts improved massively.
"Most of our previous readings were wrong," says Obbink. "We could not
believe our eyes. We were 'blinded' by the real readings. The text
wasn't what we thought it was and now it made sense."
... And the same scroll seen in
multi-spectral infrared light. There are four columns of text, with many
gaps. The first column begins: "… hold power… think… but in both
circumstances 'one wise counsel conquers many hands', and usually
affairs succeed by this means, both without weapons and with a moderate
force. This did not escape the poet, but he himself called Nestor
'bulwark of the Achaeans' because he was most experienced among them..."
In 2008, a further advance was made through multi-spectral
imaging. Instead of taking a single ("monospectral") image of a fragment
of papyrus under infrared light (at typically 800 nanometres) the new
technology takes 16 different images of each fragment at different light
levels and then creates a composite image.
Handwriting styles can be identified
With this technique Obbink is seeking not only to clarify the
older infrared images but also to look again fragments that previously
defied all attempts to read them. The detail of the new images is so
good that the handwriting on the different fragments can be easily
compared, which should help reconstruct the lost texts out of the
various orphan fragments. "The whole thing needs to be redone," says
Obbink.
So what has been found? Lost poems by Sappho, the 100-plus
lost plays of Sophocles, the lost dialogues of Aristotle? Not quite.
Despite being found in Italy, most of the recovered material is in Greek. Perhaps the major discovery is a third of
On Nature, a previously lost work by the philosopher Epicurus.
But many of the texts that have emerged so far are written by
a follower of Epicurus, the philosopher and poet Philodemus of Gadara
(c.110-c.40/35BC). In fact, so many of his works are present, and in
duplicate copies, that David Sider, a classics professor at New York
University, believes that what has been found so far was in fact
Philodemus's own working library. Piso was Philodemus's patron.

The Villa dei Papyri scrolls
- Some 2,000 scrolls have been recovered from the villa, of which some 1,600 to 1,700 have been unrolled
- Most are philosophical works in Greek, many by Philodemus of
Gadara, identified as author of 44 scrolls and probable author of
another 120 sections of scroll
- Other works include a comedy in Latin by Caecilius Statius
called Faenerator, or The Usurer, about a young man who borrows money
at high interest to get his girlfriend out of the hands of a pimp
Not all of the villa's scrolls
have been unrolled though - and because of the damage they suffer in the
unwinding process that work has now been halted. Might it be possible
to read them by unrolling them not physically, but virtually?
In 2009 two unopened scrolls from Herculaneum belonging to
the Institut de France in Paris were placed in a Computerised Tomography
(CT) scanner, normally used for medical imaging. The machine, which can
distinguish different kinds of bodily tissue and produce a detailed
image of a human's internal organs could potentially be used to reveal
the internal surfaces of the scroll.
The task proved immensely difficult, because the scrolls were so tightly wound, and creased.
"We were able to unwrap a number of sections from the scroll
and flatten them into 2D images - and on those sections you can clearly
see the structure of the papyrus: fibers, sand," says Dr Brent Seales, a
computer science professor at the University of Kentucky, who led the
effort.
But the machine could not distinguish "the chemistry of the ink
from the chemistry of the paper," he says. It is unfortunate that
ancient ink contains no metal.
Seales is continuing to analyse the data produced by the 2009
scan. He has also begun testing a new way of reading the scrolls, using
a beam from a particle accelerator.

Lost Libraries
- During Hellenistic Period (323-31BC) there were several major
libraries in the Mediterranean world, the greatest being the Library of
Alexandria, established about 300BC - it was damaged in 48BC and
probably destroyed in the reign of the Roman Emperor Aurelian
(270-275AD)
- Alexandria's closest rival was the library at Pergamum, in what is now Turkey
- The Roman conquest of the kingdom of Macedon in 168 BC led to the seizure of its imperial library, which was taken to Rome
- During the Roman Empire,
major libraries were built in Rome, often with separate buildings to
hold Latin and Greek works - a catalogue of Rome's buildings from c.
350AD, 60 years before the city was burnt and looted by the Visigoths,
lists 29 public libraries in the city, all now lost
Others are more preoccupied with the idea that there may be more scrolls in the villa waiting to be discovered.
Richard Janko, professor of classical studies at the University of Michigan is "pretty certain that there's more there".
The villa belonged to Latin-speaking Roman aristocrats,
Lucius Calpurnius Piso and his son of the same name - so, Janko reasons,
there would have been a Latin library as well as the mostly Greek
library already discovered.
Secondly, the villa was, he says, not merely a holiday home but a
mouseion—a museum-like place to show off a collection of spectacular works of art and literature. If this
mouseion
had literature to compare to its sculptures, we should expect something
more impressive than the working collection of a minor philosopher such
as Philodemus. We might even hope for an early edition of the
Aeneid, as Virgil and Philodemus knew each other.
Thirdly, scrolls were found in various places in the villa.
Although some were on shelves and in cabinets, others were piled on the
ground and packed in the tubular boxes (
capsae) in which
scrolls were carried around. Could these boxes have been brought from
another part of the building, as yet unknown, where further scrolls
remain still?
Robert Fowler, professor of classics at Bristol University,
points out that near the room where many of the scrolls were found, and
on the same level, is a section of the villa that has never been dug up.
The Swiss engineer Karl Weber, who led the dig of the villa
in the 1750s "was defeated by the nature of the material in the site
next to where the scrolls were found," he says.

Lost works
We have perhaps only some 10% of the major works of classical
literature, according to Robert Fowler. Most works in most genres are
lost. His wish list of lost works includes:
- Aeschylus - only 7 of his 80 plays survive
- Aristophanes - 11 out of 40 plays survive
- Ennius - his epic poem Annales, is almost entirely lost
- Euripides - 18 of his 90 plays survive
- Livy - three-quarters of his History of Rome are lost
- Sappho - most of her nine books of lyric poems are lost
- Sophocles - only 7 entire plays survive of 120 he wrote
And the villa also has three
levels. Only the topmost has been substantially explored so far, but in
the 1990s two other layers were partially revealed. In the middle floor,
archaeologists have discovered a range of well-furnished rooms with
views out to sea, some of which have been opened up while others remain
closed. Could this be where the villa's owners kept their good stuff?
So far, all we have are guesses. Only digging will provide
proof. But Fowler remains hopeful that the villa could yet contain a
literary "bonanza". Someday, he is sure, we shall be able to re-read the
ancient scrolls.
The Italian authorities are reluctant to permit further
excavation, arguing that this would be disruptive for residents of the
modern town of Ercolano, built literally on top of Herculaneum. They
also point out that 300-400 of the original rolls remain unread.
In the meantime Fowler tries to keep up the pressure. He
reckons that we have perhaps 10% of the great works of classical
literature, so any chance to recover the rest is precious.
"Just imagine if there were two plays by Shakespeare which we
knew of but had never read and which we believed lay underground in a
particular place: do you think we would question the decision to dig
them up? Do you think we would be hesitating?"
And if we did need another reason for speed, there is always
the volcano. Mount Vesuvius has erupted a dozen times in the last 200
years, the last major eruption in 1944. As Richard Janko says, another
big eruption might end our chance of recovering the ancient literature
in Herculaneum for ever.
