I’ve seen many animations of life in ancient cities. Most of them show rather pristine, antiseptic scenes. (Here is an example of one: Ancient Corinth.) Such animations don’t show the noisy, cluttered open markets or the garbage and human waste in the streets.
The video below, however, does a fairly good job of depicting the less-seemly aspects of ancient Athens. Watch it and see Athens the way it likely was in St. Paul’s day. While the animations were developed for a video game, many scholars have been impressed by the archaeological and sociological authenticity.
