How the Romans saw their world. If you turn it North up it's mostly right. The edges ar too cold or too far or in the case of the rest of Africa too hard to live in with there lifestyle. Too many diamonds would ruin their social construct and world trade anyway.
Daily life around a Roman insula. Roman apartment buildings contained vendors on the first floor and living quarters on the floors above. The apartments in the insulae lacked most basic amenities, such as kitchens and bathrooms. As a result, Romans lived a highly communal lifestyle. The lower classes used public baths and toilets, ate in restaurants, and spent leisure time in common spaces, like the forum.
