Welcome to Ancient Rome! It is 55AD.
You have landed in a dusty hot street which is full of people pushing past you. There is wood smoke in the air as well as a distinct smell of rubbish. On either side of the street there are shops that seem to be selling olive oil, bread and other kinds of food. Men are walking round selling soup and bread from trays on their head. There are all kinds of people about–from beautifully dressed women in long gowns, occasional Roman soldiers, and slaves shopping for their mistresses.
Over the tops of the tall buildings you can see that the sun is getting lower in the sky. Some people come up to you “Hey, it is getting dark soon and you don’t want to be out in Rome on your own after night fall do you?” Who would you like to go with?
