Fontana's covering over the paintings has been seen both as censorship—in view of the frequent sexual content of such paintings—and as a broad-minded act of preservation for later times, as he would have known that paintings of the hedonistic kind later found in some Pompeian villas were not considered in good taste in the climate of the counter-reformation.
"Garden of the Fugitives". Plaster casts of victims still in situ; many casts are in the Archaeological Museum of Naples.
Karl Weber directed the first real excavations; he was followed in 1764 by military engineer Franscisco la Vega. Franscisco la Vega was succeeded by his brother, Pietro, in 1804. During the French occupation Pietro worked with Christophe Saliceti.
Giuseppe Fiorelli took charge of the excavations in 1863 During early excavations of the site, occasional voids in the ash layer had been found that contained human remains. It was Fiorelli who realized these were spaces left by the decomposed bodies and so devised the technique of injecting plaster into them to recreate the forms of Vesuvius's victims. This technique is still in use today, with a clear resin now used instead of plaster because it is more durable, and does not destroy the bones, allowing further analysis.
The discovery of erotic art in Pompeii and Herculaneum left the archaeologists with a dilemma – between the mores of sexuality in ancient Rome and in Counter-Reformation Europe lay a clash of cultures. An unknown number of discoveries were hidden away again. A wall fresco depicting Priapus, the ancient god of sex and fertility, with his extremely enlarged penis, was covered with plaster. An older reproduction was locked away "out of prudishness" and opened only on request—and only rediscovered in 1998 due to rainfall.
A large number of artifacts from the buried cities are preserved in the Naples National Archaeological Museum. In 1819, when King Francis visited the Pompeii exhibition there with his wife and daughter, he was so embarrassed by the erotic artwork that he decided to have it locked away in a so-called "secret cabinet" (gabinetto segreto), a gallery within the museum accessible only to "people of mature age and respected morals". Re-opened, closed, re-opened again and then closed again for nearly 100 years, the Naples "Secret Museum" was briefly made accessible again at the end of the 1960s (the time of the sexual revolution) and was finally re-opened for viewing in 2000. Minors are still allowed entry only in the presence of a guardian or with written permission.
