What did the merchants buy when they arrived in Babylon?

In ancient times, Babylon was not only a great cultural center, but also a center of trade in the east. Merchants bought here: dishes, copper, tin, purple, grain, livestock, fruits, etc. The city of Babylon itself arose as early as 3 thousand BC. It gradually expanded. Already in 2 thousand BC, it became the capital of the Babylonian kingdom. Then there was a period of decline. A new heyday of the city began in the 6th century BC, when the New Babylonian kingdom appeared.
