When and why was a Greek urn made?

Greek urns, particularly amphorae and kraters, were crafted primarily during the Geometric period (circa 900-700 BC) and the subsequent Archaic period (circa 700-480 BC). They were created for various purposes, including storage of goods like oil and grain, as well as for funerary practices or as offerings to the gods. The intricate designs and illustrations on these urns often depicted mythological scenes, daily life, and athletic competitions, reflecting the cultural and artistic values of ancient Greek society.
