MAP 6.2 Natural Features and Languages of the Roman World
The environment of the Roman world included a large variety of topography, climate, and languages. The inhabitants of the Roman Empire, estimated to have numbered as many as fifty million, spoke dozens of different tongues, many of which survived well into the late empire. The two predominant languages were Latin in the western part of the empire and Greek in the eastern. Latin remained the language of law even in the eastern empire. Vineyards and olive groves were important agricultural resources because wine was regarded as an essential beverage, and olive oil was the principal source of fat for most people as well as being used to make soap, perfume, and other products for daily life. Dates and figs were popular sweets in the Roman world, which had no refined sugar.
