Question 4
Original passage
Most of what visitors to Pompeii see today reflects only one moment in the city's history, how it looked in A. D. 79 when it was buried by volcanic ash from the eruption of Mount Vesuvius. We are now learning about the history of this block, from its beginnings more than four hundred years earlier. We can show how it was first occupied in the fourth century B. C., filled in with modest houses and workshops in the second century B. C., bombarded by a Roman army a century later, then came to be dominated by a single luxurious residence surrounded by bars and shops. Many of the questions we are asking are new ones, about the origins of the city: when its streets were laid out, how the densely packed townscape of A. D. 79 came into being, the relationships between rich and poor, and how the masses earned a living.
From Rick Jones, "Pompeii's Block of Time." Archaeology July/August 2003: 23-24.
SUMMARY: Jones recounts how archaeologists are uncovering the history of a block and its residents in Pompeii from when it was first settled in the fourth century B. C. through the eruption of Mount Vesuvius in A. D. 79. At first the block was populated by simple homes and workshops, but it later had only one lavish home with bars and shops around it (23-24).
