Answer:
"Von" is used in front of adverbs, as well as to manifest starting point and point of arrival. When you want to indicate origin, referring to the place of origin, "aus" is used, except in front of adverbs, and also to express that it comes from a certain building or means of transport.
It was first practiced in Greek city-states, notably in Athens.
