Pompeii:The Facts
August 24,in the year AD 79,began normally for the people in Pompeii,a town at the foot of Mount Vesuvius. Farmers went out to their fields,shopkeepers set out their goods for sale,crafts people opened their workshops and the rich walked to the public baths while their servants cleaned their houses and washed their clothes. Unfortunately,the end of the day was far from normal for the 20,000 citizens of Pompeii.
Early in the afternoon,when many people were resting from the heat of the day,Mount Vesuvius erupted. Millions of tons of ash ,lava and pumice poured onto the surrounding hillside and over the town of Pompeii and other towns and villages. By evening Pompeii was buried under 3 ~ 5 metres of ash and mud,and at least 2,000 men,women and children were buried with their town.
