During volcanic eruptions, (above, Iceland's Eyjafjallajokull volcano) colliding particles of ash create immense levels of electricity, released as volcanic lightning.

The Eruption of Mt. Vesuvius

The Eruption of Mt. Vesuvius in 79 CE remains one of the deadliest natural disasters in recorded history. Not only did the volcano destroy the economically powerful city of Pompeii, but Herculaneum, Oplontis, Stabiae were also buried and thus lost to the Roman Empire. The number of victims is unknown, but given the size of the four cities, estimates have reached over 18,000 individuals.  

Today only one first-hand account of this horrific event survives in two letters from Pliny the Younger to the Roman historian Tacitus. They are preserved as letters 6.16 and 6.20 in the collected Epistles of Pliny. Among our holdings of the works of Pliny is this 3-volume set of the Epistles with William Melmoth’s 18th-century translation edited by Clifford Herschel Moore, and printed by the Harvard University Press in an edition of 405 copies for members of The Bibliophile Society, Boston, in 1925.

While the term ‘volcanic eruption’ evokes scenes of lava and fire, the reality is much more frightening. Curiously, there is no word for volcano in the Latin language. While ancient Romans were aware of the destructive power of volcanoes, there’s some debate about whether they were aware that Vesuvius was a volcano before its eruption. Signs of the eruption began back in 62CE with a great earthquake that caused much of the city to collapse. Smaller earthquakes continued over the next 15 years until one was accompanied by the rise of a column of smoke from Mt. Vesuvius in October 79 CE. 

The hot gases that made up the column of smoke began to cool, darkening the sky, and not long after a rain of pumice began to fall, and after 15 hours ceilings began to collapse. Nevertheless, many residents chose to take shelter rather than flee. At 4am the first 500C pyroclastic surge barred down the volcano, burying Herculaneum. Six more of these surges occurred before the end of the eruption, destroying Pompeii, Oplontis, and Stabiae. 

The 17-year old Pliny was in the port town of Misenum across the Bay of Naples from the volcano at the time. Pliny’s uncle, Pliny the Elder, commander of the Roman fleet at Misenum, launched a rescue mission and went himself to the rescue of a personal friend. The elder Pliny did not survive the attempt. In Pliny the Younger’s first letter to Tacitus, he relates what he could discover from witnesses of his uncle's experiences. In a second letter, he details his own observations after the departure of his uncle.

Mt. Vesuvius is still active and according to volcanologists, erupts about every 2000 years, which would be right about now. Who will be our next Pliny the Younger?

Our copy of The Epistles of Pliny is another gift from our friend and benefactor Jerry Buff.

The Ancient Greek papyri that was burned in 79 AD following the eruption of Mount Vesuvius has now been revived with the content also having been recovered.

There were more than 1,800 papyri, sometimes referred to as the Herculaneum scrolls, with texts hidden on the back.

Initially, scientists attempted to unroll the papyri and, as a result of their hasty efforts, ruined them in their already fragile state. Yet recently, a group of researchers from Italy, France, Germany, and Russia collaborated on the papyri with advanced digital technology.

They then announced that “by using the ultrasound imaging technique in the short infrared portion of the electromagnetic spectrum (1,000 to 2,500 nanometers), they were able to see “portions of Greek text hidden behind the PHerc. 1691/1021 papyrus.”
