Pompeii was a Roman city situated close to present-day Naples in Italy.
In 79 AD, the city was completely buried, following the eruption of the Mount Vesuvius volcano.
It was rediscovered in 1592, and excavation work was carried out from the mid-18th Century onwards.
The murals uncovered at the site were classified into four categories, each of which was painted at different periods in the history of the city.
The second category, for example, contains paintings of the trompe-l'oeil type (giving the impression of three dimensions), whilst the fourth category is characterised by dramatic narrative scenes and panoramic vistas.
