At the foot of mount Vesuvius there existed, until
the fated year of 79 AD, a Roman town named Herculaneum. Legend says it
was founded by the Greek hero Ἡρακλῆς (Heracles, known
to the Romans as Hercules) himself while returning from Iberia after one of his
twelve labors, and named after him. While not as large as the nearby city of Pompeii, its position at (what was then) the seaside
made it a retreat for Roman nobility including, it is believed, Julius Caesar's
father-in-law, Lucius Calpurnius Piso Caesonius, and its four thousand
inhabitants enjoyed decent prosperity.
That, of course, changed radically with the eruption. At around 1AM heat waves
of up to 400°C reached the town, traveling at 160km/h, killing those who
remained instantly and burying the area under 20m of volcanic ash.
More than a millennium and a half would pass until the town was accidentally
rediscovered in 1709 during the excavations for the construction of a well.
Because of its position away from the wind direction in that particular day of
the eruption, its destruction was much reduced compared to other places around
the gulf such as Pompeii, making it unique in how
well-preserved its structures are, as well as the artifacts found inside them
(most of which are now on display in the museo
archeologico nazionale di Napoli).
The modern Italian city of Ercolano, renamed after the ancient Roman town it was
built (unknowingly) upon, is located 450m away from what is today the coast, and
the ancient ruins are now 4m below sea level. Around ¾ still remain buried, as
efforts have lately been focused on preserving the rapidly-deteriorating parts
which have already been excavated. This is also the reason why some of these
pictures are not at ideal and sometimes are even at awkward angles: many of the
houses, rooms, and spaces are not accessible so they can be better preserved and
renovated.
New discoveries are constantly made. A recent example was the unearthing of
more than three hundred human skeletons in 1980 inside what were then the docks,
revealing the last moments of those who remained and waited to be rescued by
brave sailors, such as (and as is famously recounted by) Pliny the Elder.
Another recent excavation area, currently closed for the public, is Villa dei Papiri, named
after the many ancient texts found in its vast library (if you ever need further
evidence of the decadence of Western society — not that there is a short supply
— think about how nobility in Roman times went to the seaside to read Greek
texts about Epicurean philosophy). Getty Villa in Los Angeles
is a reconstruction of the Herculaneum villa, illustrating how it and the other
houses looked like at its prime just before the eruption.
