What did the merchants from the city of Greece bring to the colonies?

Merchants imported from the cities of Greece to their colonies: marble, wine, olives, weapons, dishes, horses, etc. Greece in ancient times consisted of large city-states, in each of which trade developed. The largest trading city was Athens. The trading life of all Greece was practically concentrated here. There was also a large commercial port of Piraeus, which contributed to the development of trade. Ships from different parts of Middle-earth sailed here, and the ships of the Greeks returned here.
