see PAGE NOT FOUND | Loyola University Chicago LibrariesIn this work Neapolitan Jesuit G. B. Mascolo records his observations of the eruption of Mount Vesuvio in 1631. The illustrations record the appearance of the volcano and the surrounding area before and after the eruption.On a map there is Pompeii and Herculaneum (1631 Year )Edited by elcano, : No reason given.

Welcome to the fray elcanoVesuvius erupted in both 79ad and 1631adSurprisingly the result covered much of the same area ... or is it just a coincidence of geography?Somehow the evidence that there was an eruption in 1631ad seems to be taken by some to mean that what occurred in 79ad did NOT occur?This is not the case, there are layers involved here and geologists can and do tell the difference.Likewise there are artifacts that were buried by each that show different types, manufacture, color, construction, etc. with the 79ad ones being consistent with roman work and the 1631ad ones being consistent with a medieval europe.Enjoy.Edited by RAZD, : wording clarificationEdited by RAZD, : subtitle

In addition, the 79CE eruption was recorded by Pliny the Younger and can be found in Book 1 of his Letters IIRC.

Aslan is not a Tame Lion

Any medieval subject to Pompeii it is not found. Above this city only one layer of the ground from eruption Vesuvius. (7-10 meters, either 79 year, or 1631)

Vesuvius has erupted many times. The famous eruption in 79 was preceded by numerous others in prehistory, including at least 3 significantly larger ones, the best known being the Avellino eruption around 1800 BC which engulfed several Bronze Age settlements. Since 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500.[6] The volcano erupted again in 1631, six times in the 18th century, eight times in the 19th century (notably in 1872), and in 1906, 1929, and 1944. There has been no eruption since 1944, and none of the post-79 eruptions were as large or destructive as it.

​

The eruptions vary greatly in severity but are characterized by explosive outbursts of the kind dubbed Plinian after Pliny the Younger, the Roman naturalist who observed the 79 eruption, and whose uncle Pliny the Elder possibly fell victim. On occasion, the eruptions have been so large that the whole of southern Europe has been blanketed by ashes; in 472 and 1631, Vesuvian ashes fell on Constantinople (Istanbul), over 1,200 km away. A few times since 1944, landslides in the crater raised clouds of ash dust, which caused false alarms of an eruption.

OR it really did happen several times of which 79ad and 1631ad are only two examples.Given the multiple evidence of recorded eruptions to argue there was only one such in all of history is denial of evidence at it's best.Enjoy.

Pliny the Younger in the book of 6 letters 16 and 20 describes eruption of Vesuvius. However it does not result date of eruption. Pliny the Younger in general anywhere does not mention Pompeii, it does not know such city.
See IIS 8.5 Detailed Error - 404.0 - Not Found

Eruptions of Vesuvius was much. Archeologists have found to Pompeii a volcanic layer only from one eruption which they dated 79 year. To Pompeii it has not been found any traces from other eruptions.

Ash from other eruptions has fallen on pompeii, just not as much as occurred in 79ad. The last biggish one was 1631.What is your issue with dating vesuvius? I see from your proposed new topic that you have some fantasy about carbon14 dating being invalidated by this argument, but that just is not so either: carbon14 does not rely on vesuvius for calibration or validation.See Carbon-14: A Scientifically Proven Dating Method? and Request for Carbon-14 Dating explanation for a couple (brief) discussions on carbon-14 - if you want to ask some questions or post what you think is a problem for carbon-14 there then we can discuss that as well.If this is your whole raison d'etre for the vesuvius argument you are in for some tough going.Enjoy.

The ashfall from 79 AD has also been dated by argon-argon methods, and to within +/- 94 years: Renne, et al., Science 29 August 1997: Vol. 277. no. 5330, pp. 1279 - 1280:

A Plinian eruption ejects a column of tephra high into the atmoshpere (tephra refers to any material that is ejected from a volcano into the atmosphere), creating a form similar to the mushroom cloud of a nuclear explosion. A Plinian eruption of Vesuvius began at midday on 24 August 79 AD created a Plinian column approximately 20 km (66,000 feet) high. This phase created a rain of ash and pumice over a broad area primarily to the south of Vesuvius, carried by prevailing winds. This phase lasted approximately eighteen hours, when approximately 2.5 meters (8.2 feet) of pumice stones fell on Pompeii, an initial layer of 1.3 to 1.4 meters (4.3 to 4.6 feet) of white pumice, followed by 1.1 to 1.3 meters (3.6 to 4.3 feet) of denser gray pumice. The average diameter of the pumice fallout was 1 cm (0.4 in), and posed little direct threat to human life.http://urban.arch.virginia.edu/struct/pompeii/volcanic.htmlOnly such layers and only from eruption 79 years.

P.R. Renne assumes :
“We sought to investigate the limits of the 40Ar/39Ar method by application to ejecta from the infamous eruption of Vesuvius? Which destroyed Pompeii and other Roman cities, AS DOCUMENTED IN THE WRITINGS OF PLINY THE Yanger”
http://hbar.phys.msu.ru/gorm/dating/vesuvius.pdf
The given assumption false.
Pliny Younger does not know year of eruption of Vesuvius and does not know the city of Pompeii.

The biggest during recorded history was 79ad, but not the only one.You've been given evidence that this is so. Repeating your denial or your claim that there was only one does not make it true.What else do you have? If this is the sum of your issue then I am done.

Dio Cassius (AD 150-235) Roman Poet Marcus Valerius Martialis (AD 40-104)Pliny the Younger was not the only person to have recorded the eruption in 79 AD. The End of Pompeii and Herculaneum (August 24-25, A.D. 79) Part 3 of 3

I do not speak, that there is a layer only from eruption 79 years, It archeologists speak all, that me extremely surprises. And on a monument costing in Torre del Greco it is written Pompeii and Herculaneum were lost on December, 16th, 1631. What are possible conclusions?

Yes you correctly speak. Pliny the Younger and Martialis know about eruption of Vesuvius but in what to year it has occured they to us do not inform.
They do not know the city of Pompeii and Herculaneum.
Only Dio Cassius (Xiphilinus is the author of 11 centuries) knows about destructions of Herculaneum and Pompeii.
The first edition of the book Xiphilinus was in 1551.
There are no other ancient authors knowing about destruction Pompeii and Herculaneum, only Xiphilin.
