With the rediscovery of Pompeii and Herculaneum, Vesuvius has had a craze in the 18th and 19th century.
The practice in vogue the Knight's Tour, more commonly known as the Grand Tour, distinguished by young Europeans training trip to diplomatic, military and cultural practices, will match in the Neapolitan region with the golden age of Neapolitan Gouaches.
Mostly anonymous, and of small formats for an easy transport, these crafts, "souvenirs of trip", have robbed the rich tourists.
Using gouache or watercolor is the need for make these works quickly and in large numbers. Two formats are preferred: 30/40 cm. to be framed, or by 5/10 10/15 cm. favor of album layout. Usually surrounded by a black frame, they bear the handwriting of the day or the year of the eruption portrayed.
Among them, the works of Camillo de Vito illustrate Vesuvius eruptions staggered between 1812 and 1822.
They differ from works usually quite dark ... "balanced" by a brightness in a part of the gouache, made by a reflection on the Bay of Naples, a quarter of Moon, some people with light in the foreground, or simple fumaroles.
Cone, incandescent fallout and flows, or light reflections from lava on the clouds, are all specific ... and show an application of the author.
The eruptions of Vesuvius, between 1812 and 1830, are usually effusive or effusivo-explosive, and concern both the top and the sides of the volcano.
The Neapolitan gouaches, although imperfect or made in haste, are valuable testimonies before the first photographs made during the eruption of 1872.
