Pompeii has had many historians discuss it in the 19th and 20th centuries. The archaeologists provide a much clearer view of what the cities of Vesuvius were like than the writers of literary sources, such as Pliny the younger writing to Tacitus about his uncle Pliny the elder. Some other sources (mostly archaeological) suggest that Pompeii was a thriving city at the time of the 79AD eruption, such as the luxurious villas contained in the city. There are various other people who have accounts on the events that occurred in Pompeii. Pompeii was a much bigger site than Herculaneum, and would have been much harder to excavate. It currently resides under a present town, Medina, so no further excavations can take place. The evidence that has been found at Pompeii has been pretty much conclusive. Dr. Sarah Bisel was one of the most prominent archaeologists at Herculaneum. She discovered just under 150 skeletons at the site, and analysed them using scientific methods. She discovered children, men and women at the site. The only way that scientific methods can be implemented is with extreme caution and expertise. Although Dr. Giuseppe Maggi was the one who actually discovered the skeletons, he needed the expertise of Sara Bisel. Bisel used two core anthropological methods: biochemical analysis, which looks at chemical reactions performed by the body and measurement and observation of bones. The biochemical analysis found extremely high levels of lead in several skeletons. This method of archaeology could not be used without vast scientific advancements in the 20th century. Different archaeologists have different historical contexts in which to be appropriate in, and this affects their finds, and their actions after finds have been discovered. Maori, for example would have used different archaeological methods to Bisel, and would have had access to different information. Andrew Wallace-Hadrill said: “The past is shaped and re-shaped in the present. Just as musicians interpret and re-interpret musical scores, and actors endlessly re-interpret William Shakespeare’s plays, different interpretations bring out different meanings.” (The Range of sources and their reliability, pg 38) What he meant by this was that the reliability of sources at the cities of Vesuvius was incoherent, “as a result of past neglect, damage to the sites and failure to scribe carefully” (The Range of sources and their reliability, pg 37). The plaster casts of victims made by Fiorelli’s process (using plaster) show the clothes that the people were wearing and the objects they were carrying, which gives us an excellent look into the state that the people were in before the eruption, what they were doing before the eruption and how this evidence relates to the current economic current before the eruption. There are several “found out” exploitations of discoveries. One such example is the finding of “the skeletons of Hadraldar”, which were found by three sets of Royalty, obviously to influence them, and this is an indication of how evidence derived from the past can be swayed by the theory of treasure hunting. Archaeologist Wilhemina Jashemski performed an extensive investigation of the gardens and orchards using plaster casts of the cavities, which was formed around the roots and vines. She also used analysis of dead ash. Both of these techniques gave Jashemski the opportunity to identify the flora at the time of the eruption. Archaeologists have since been able to re-create some of the gardens in the finer residences and a large vineyard near the amphitheatre. This evidence has shed light onto the economical stance of Pompeii before the eruption, with the relationship between rural and urban areas seemingly used. Another example of flora identification is Henry De St Blanquet’s discovery of 31 parasitic plants, which over time can dislodge tiles and mosaics, weaken mortar which destabilizes walls. These discoveries allowed Blanquet to see that the water and drainage systems in Pompeii were extremely bad condition, which gives us a greater understanding of the possible medical problems that people from Pompeii and Herculaneum might have had. This influences our judgement of these people, changing from lack of hygiene and/or medical knowledge to invisible problems in the basic stages of Pompeii’s and Herculaneum’s infrastructure. Tourism is a “catch 22” when it comes to the preservation of sites. It brings in revenue to pay for staff, but at the same time, tourism actually destroys the sites. Amedeo Mauiri was the director of excavations at Pompeii from 1924 to 1961. He made an endeavour to progress the infrastructure of the two towns. He attempted to do this with materials of concrete and steel, which didn’t match the original materials and also damaged the structure. This mistake could have been one of many discovered at Pompeii and Herculaneum, and shows the unreliability of sources at Pompeii and Herculaneum based on the material choice. The methods used by archaeologists at Pompeii obviously reflect the time period they were in, and the level of accessibility to sources. The general consensus is that the methods get more crisp, smooth and thorough as time goes by. There is also a lack of evidence from earlier in the 19th century and early 20th century, which condemns all evidence derived from that period to be unreliable. This is partly due to the fault of the archaeologists, but a lack of experience or knowledge could also be claimed. Archaeologists have a duty to record information from a site, but this duty was relieved of the earlier archaeologists, since there is little or no documentation being recorded.
