Located in the shadow of Mount Vesuvius, Herculaneum (Italian: Ercolano) was an ancient Roman town destroyed by volcanic pyroclastic flows in 79 AD. Its ruins are located in the comune of Ercolano, Campania, Italy.
As a UNESCO World Heritage Site, it is famous as one of the few ancient cities that can now be seen in much of its original splendour, as well as for having been lost, along with Pompeii, Stabiae, Oplontis and Boscoreale, in the eruption of Mount Vesuvius in AD 79 that buried it. Unlike Pompeii, the deep pyroclastic material which covered it preserved wooden and other organic-based objects such as roofs, beds, doors, food and even some 300 skeletons which were discovered in recent years along the seashore. It had been thought until then that the town had been evacuated by the inhabitants.
Herculaneum was a wealthier town than Pompeii, possessing an extraordinary density of fine houses with, for example, far more lavish use of coloured marble cladding.
Ancient tradition connected Herculaneum with the name of the Greek hero Herakles (Hercules in Latin and consequently Roman Mythology), an indication that the city was of Greek origin. In fact, it seems that some forefathers of the Samnite tribes of the Italian mainland founded the first civilization on the site of Herculaneum at the end of the 6th century BC. Soon after, the town came under Greek control and was used as a trading post because of its proximity to the Gulf of Naples. The Greeks named the city , Heraklion. In the 4th century BC, Herculaneum again came under the domination of the Samnites. The city remained under Samnite control until it became a Roman municipium in 89 BC, when, having participated in the Social War ("war of the allies" against Rome), it was defeated by Titus Didius, a legate of Sulla.
After the eruption of Mount Vesuvius in 79 AD, the town of Herculaneum was buried under approximately 20 metres (50-60 feet) of ash. It lay hidden and largely intact until discoveries from wells and underground tunnels became gradually more widely known, and notably following the Prince d'Elbeuf's explorations in the early 18th century. Excavations continued sporadically up to the present and today many streets and buildings are visible, although over 75% of the town remains buried. Today, the Italian towns of Ercolano and Portici lie on the approximate site of Herculaneum. Until 1969 the town of Ercolano was called Resina. It changed its name to Ercolano, the Italian modernization of the ancient name in honour of the old city.
The catastrophic eruption of Mt. Vesuvius occurred on the afternoon of 24 August AD 79. Because Vesuvius had been dormant for approximately 800 years, it was no longer even recognized as a volcano.
At around 1pm on 24 August, Vesuvius began spewing volcanic ash and stone thousands of meters into the sky. When it reached the tropopause (the boundary between the troposphere and the stratosphere), the top of the cloud flattened, prompting Pliny to describe it to Tacitus as a Stone Pine tree. The prevailing winds at the time blew toward the southeast, causing the volcanic material to fall primarily on the city of Pompeii and the surrounding area. Since Herculaneum lay to the west of Vesuvius, it was only mildly affected by the first phase of the eruption. While roofs in Pompeii collapsed under the weight of falling debris, only a few centimetres of ash fell on Herculaneum, causing little damage but nonetheless prompting most inhabitants to flee.
During the following night, the eruptive column which had risen into the stratosphere collapsed onto Vesuvius and its flanks. The first pyroclastic surge, formed by a mixture of ash and hot gases, billowed through the mostly evacuated town of Herculaneum at 160 km/h (100 mph). A succession of six flows and surges buried the city's buildings, causing little damage in some areas and preserving structures, objects and victims almost intact. However, in other areas there was significant damage, knocking down walls, tearing away columns and other large objects; a marble statue of M. Nonius Balbus near the baths was blown 15 m away and a carbonised skeleton was found lifted 2.5 m above ground level in the garden of the House of the Telephus Relief.
Recent multidisciplinary research on the lethal effects of the pyroclastic surges in the Vesuvius area showed that in the vicinity of Pompeii and Herculaneum, heat was the main cause of the death of people who had previously been thought to have died by ash suffocation. This study shows that exposure to the surges, measuring at least 250 °C (482 °F) even at a distance of 10 kilometres from the vent, was sufficient to cause the instant death of all residents, even if they were sheltered within buildings.
In 1709 the digging of a deep well revealed some exceptional statues at the lowest levels which was later found to be the site of the theatre. The Prince d'Elbeuf purchased the land and proceeded to tunnel out from the bottom of the well, collecting any statues they could find. Among the earliest statues recovered were the two superbly sculpted Herculaneum Women now in the Dresden Skulpturensammlung.
Major excavation was resumed in 1738 by Spanish engineer Rocque Joaquin de Alcubierre. The elaborate publication of Le Antichità di Ercolano ("The Antiquities of Herculaneum") under the patronage of the King of the Two Sicilies had an effect on incipient European Neoclassicism out of all proportion to its limited circulation; in the later 18th century, motifs from Herculaneum began to appear on stylish furnishings, from decorative wall-paintings and tripod tables to perfume burners and teacups. However, excavation ceased once the nearby town of Pompeii was discovered, which was significantly easier to excavate because of the thinner layer of debris covering the site (4 m as opposed to Herculaneum's 20 m).
Barker noted in his 1908 Buried Herculaneum, "By the orders of Francis I land was purchased, and in 1828 excavations were begun in two parts 150 feet apart, under the direction of the architect. Carlo Bonucci. In the year 1868 still further purchases of land were made, and excavations were carried on in an eastward direction till 1875. The total area now open measures 300 by 150 perches (1510 by 755 8 metres). The limits of the excavations to the north and east respectively are the modern streets of Vico di Mare and Vico Ferrara. It is here only that any portion of ancient Herculaneum may be seen in the open day."
From 1927 until 1942 a new campaign of excavations was begun by Amedeo Maiuri, which exposed about four hectares of the ancient city in the archaeological park that is visible today.
Excavation resumed briefly in the town in 1980-81 on the ancient shoreline following which the skeletons in the boathouses were found.
From 1996-99 the large area to the north-west of the site was excavated and exposed, including part of the Villa of the Papyri, the north-west baths, the House of the Dionysian Reliefs and a large collapsed monument. This area was left in a chaotic state and from 2000-7 further work on conservation of this area was done.
Many public and private buildings, including the forum complex, are yet to be excavated.
The buildings at the site are grouped in blocks (insulae), defined by the intersection of the east-west (cardi) and north-south (decumani) streets. Hence we have Insula II - Insula VII running counterclockwise from Insula II. To the east are two additional blocks: Orientalis I (oI) and Orientalis II (oII). To the south of Orientalis I (oI) lies one additional group of buildings known as the "Suburban District" (SD). Individual buildings having their own entrance number. For example, the House of the Deer is labelled (Ins IV, 3).
The first building in insula II is the House of Aristides. The entrance opens directly onto the atrium, but the remains of the house are not particularly well preserved due to damage caused by previous excavations. The lower floor was probably used for storage.
The second house in insula II got its name from a fresco of Argus and Io which once adorned a reception room off the large peristyle. The fresco is now lost, but its name lives on. This building must have been one of the finer villas in Herculaneum. The discovery of the house in the late 1820s was notable because it was the first time a second floor had been unearthed in such detail. The excavation revealed a second floor balcony overlooking Cardo III, as well as wooden shelving and cupboards; however, with the passing of time, these elements have been lost.
To the north of the House of Argus lies the House of the Genius. It has been only partially excavated but it appears to have been a spacious building. The house derives its name from the statue of a cupid that formed part of a candlestick. In the centre of the peristyle are the remains of a rectangular basin.
The house is actually two buildings joined together. As a consequence of this it is a mixture of plain and simple rooms combined with some highly decorated ones.
The atrium is covered, so lacks the usual impluvium. It retains its original flooring of opus tesselatum and opus sectile. Off the atrium is a biclinium richly decorated with frescoes in the fourth style and a large triclinium which originally had a marble floor. A number of other rooms, one of which is the apsed alcove after which the house was named, can be reached via a hall which gets its light from a small courtyard.
The Central Thermae were bath houses built around the first century AD. Bath houses were very common at that time, especially in Pompeii and Herculaneum. Per common practice, there were two different bath areas, one for men and the other for women. These houses were extremely popular, attracting many visitors daily. This cultural hub was also home to several works of art, which can be found in various areas of the Central Thermae site.
The most famous of the luxurious villas at Herculaneum is the "Villa of the Papyri." It was once identified as the magnificent seafront retreat for Lucius Calpurnius Piso Caesoninus, Julius Caesar's father-in-law; however, it has emerged that the objects thought to be associated with Lucius Calpurnius Piso Caesonius correspond more closely to a greatly standardized assemblage, and cannot indicate, with certainty, the owner of the villa. The villa stretches down towards the sea in four terraces. Piso, a literate man who patronized poets and philosophers, built a fine library there, the only one to survive intact from antiquity.
Between 1752 and 1754 a number of blackened unreadable papyrus scrolls were serendipitously recovered from the Villa of the Papyri by workmen. These scrolls became known as the Herculaneum papyri or scrolls, the majority of which are today stored at the National Library, Naples. The scrolls are badly carbonized, but a large number have been unrolled, with varying degrees of success. Computer-enhanced multi-spectral imaging, in the infra-red range, helps make the ink legible. There is now a real prospect that it will be possible to read the unopened rolls using X-rays. The same techniques could be applied to the rolls waiting to be discovered in the as-yet unexcavated part of the villa, eliminating the need for potentially damaging the rolls by unrolling them.
A team spent a month in summer 2009, making numerous X-ray scans of two of the rolls that are stored at the French National Academy in Paris. They hoped that computer processing would convert the scans into digital images showing the interiors of the rolls and revealing the ancient writing. The main fear, however, was that the Roman writers might have used carbon-based inks, which would be essentially invisible to the scans. That fear has turned out to be fact. They had hoped that re-scanning the rolls with more powerful X-ray equipment would reveal the text. However, subsequent X-rays have still produced nothing legible. Still, the hundreds, possibly thousands of scrolls still buried at the site may yet prove to have legible text someday. As of 2016, research and experimentation has recovered more scrolls and it is suggested that new techniques will allow more to be read without unrolling them.
In 1981, under site administrator Dr. Giuseppe Maggi, excavations initially turned up more than 55 skeletons (30 adult males, 13 adult females and 12 children) on the beach and in the first six boat chambers. Because earlier excavations had revealed only a few skeletons, it was long thought that nearly all of the inhabitants had managed to escape, but this surprising discovery led to a change of view. The last inhabitants waiting for rescue from the sea were killed instantly by the intense heat, despite being sheltered from direct impact. The study of victims' postures and the effects on their skeletons indicate that the first surge caused instant death as a result of fulminant shock due to a temperature of about 500 °C (932 °F). The intense heat caused contraction of hands and feet and possibly fracture of bones and teeth.
Chemical analysis of the remains has led to greater insight into the health and nutrition of the Herculaneum population. Dr. Sara C. Bisel (1932-1996) was a physical anthropologist and classical archaeologist who played a prominent role in early scientific research at Herculaneum. Her pioneering work in the chemical and physical analysis of skeletons yielded new insights into the nutrition and health of ancient populations. This was considered ground-breaking and helped advance the field of paleodemography. Quantities of lead were found in some of the skeletons, which led some to speculation of lead poisoning. Also the presence of scarring on the pelvis, for instance, may give some indication of the number of children a woman had borne.
Casts of skeletons were also produced, to replace the original bones after taphonomic study, scientific documentation and excavation. In contrast to Pompeii, where casts resembling the body features of the victims were produced by filling the body imprints in the ash deposit with plaster, the shape of corpses at Herculaneum could not be preserved, due to the rapid vaporization and replacement of the flesh of the victims by the hot ash (ca. 500 °C). A cast of the skeletons unearthed within chamber 10 is on display at the Museum of Anthropology in Naples.
The volcanic water, ash and debris covering Herculaneum, along with the extreme heat, left it in a remarkable state of preservation for over 1600 years. However, once excavations began, exposure to the elements began the slow process of deterioration. This was not helped by the methods of archaeology used earlier in the town's excavation, which generally centered around recovering valuable artifacts rather than ensuring the survival of all artifacts. In the early 1980s and under the direction of Dr. Sara C. Bisel, preservation of the skeletal remains became a high priority. The carbonised remains of organic materials, when exposed to the air, deteriorated over a matter of days, and destroyed many of the remains until a way of preserving them was formed.
Today, tourism and vandalism have damaged many of the areas open to the public, and water damage coming from the modern Ercolano has undermined many of the foundations of the buildings. Reconstruction efforts have often proved counterproductive. However, in modern times conservation efforts have been more successful. Today excavations have been temporarily discontinued, in order to direct all funding to help save the city.
A private-public partnership, the Herculaneum Conservation Project, has taken a lead restoring Herculaneum. In 2012, UNESCO's director general praised Herculaneum as a model "whose best practices surely can be replicated in other similar vast archaeological areas across the world"
