A typical city in Roman times had many of the same businesses and professions that we have in modern cities. Pompeii, which was destroyed by the eruption of Mount Vesuvius in 79, offers a good example. Although it was small compared to Rome, the city had all the merchants and shops people needed to live their daily lives: barbers, surgeons, bakers, cloth makers, carpenters, goldsmiths, and grocers. Some professions in Pompeii that are not usually seen today included mule driving and mat making. Less educated or less skilled people could find short-term jobs, such as unloading ships or doing errands for the wealthy.
