Are history dates set in (volcanic) stone?

If the date of the Pompeii and Herculaneum destructions by a Mount Vesuvius eruption can be wrong, then what other historic dates could be?

history time lines revisionismA newly-discovered inscription at Pompeii proves the city was destroyed by Mount Vesuvius after 17 October AD79 and not on 24 August as previously thought. Archeologists recently discovered that a worker had inscribed the date of the 16th day before the calends of November, meaning 17 October, on a house at Pompeii, the head of archeology at the site, Massimo Osanna, told Italian media.

Pompeii and Herculaneum were previously thought to have been destroyed by the massive eruption of Mount Vesuvius on 24 August, based on contemporary writings and archeological finds. Nevertheless, evidence such as autumnal fruits on branches found in the ashen ruins had suggested a later date since the 19th century, Osanna said.

“Today, with much humility, perhaps we will rewrite the history books because we date the eruption to the second half of October,” said Italy’s culture minister, Alberto Bonisoli.

Revising history

Researchers into our historical time lines (chronology) have previously suggested possible small and large errors, especially where dark ages and missing strata or civilised human occupations are not found.

The discovery of the remains in May was even more startling as it appeared that the man had survived the initial phase of the eruption when the city was blanketed in volcanic ash and pumice. His torso was protruding from a large stone block but rather than being decapitated by it (the first appearance of his image online led some to call him history’s unluckiest man) archaeologist believe he was killed by the lethal gases of the eruption’s later stages.

The victim, believed to have been in his mid-30s, was also found with a small sack of 20 silver and two bronze coins, the equivalent of about €500 (£450) in today’s money.

Virtuouso said he probably took refuge in his home in the hours after the initial eruption, leaving only when he thought it was over. Experts established that he suffered from a physical defect that caused him to limp, thus hampering his escape from the doomed city.
