Pompeii is one of the most significant proofs of Roman civilization and, like an open book, provides outstanding information on the art, customs, trades and everyday life of the past. The city has re-emerged from the darkness of centuries precisely as it would have been when it was unexpectedly buried in the thick layer of ash and lava which poured down from the devastating eruption of Vesuvius. It was the year 79 A.D. The scale of the tragedy was appalling: in what had been one of the most active and splendid Roman centers, life came to a permanent standstill. The thick layer of volcanic material which submerged it, made up to a large extent of ash and lapilli – non-hard material, unlike that which covered Herculaneum and which solidified into extremely hard stone – has meant that the city has remained intact until the present day, not only as far as its buildings are concerned, but also as regards the contents inside the houses and shops, providing an absolutely fascinating picture of “daily” life. The walls of the houses are covered with electoral propaganda messages or risqué jokes aimed at particular citizens. The signs on the shop doorways indicate the activity carried out there or the name of the owner. Alongside the elegant villas belonging to the nobility and the luxurious residences of the middle class, stand modest houses where several families lived. The peasant dwellings on the other hand are situated around vegetable gardens or small plots of land. On the edge of the city stood the brothels, squalid rooms intended as places of pleasure for sailors and travelers passing through, in the narrow lanes, the workshops and utility rooms provide further evidence of the daily routine performed by workmen and slaves as well as the women of the house. The houses still contain furniture, ornaments, gold and silverware, work tools, kitchenware, bronze and terracotta lamps, foodstuffs of all kinds, counters for serving drinks, grain mills and grindstones, workshops for manufacturing cloth, smithies and outlets selling groceries, fruit and vegetables. There is a remarkable record of Roman painting, of which, without the finds made in Pompeii, virtually nothing would be known.
