Corinthian pottery is distinct in its style, in much the same way Black-figure and red-figure wares are. Corinthian pottery was the largest group of exported wares from the 7th and 6th centuries, following the Geometric style. It continued to be made up until the 5th century, although Attic pottery had grown steadily in popularity by this point. By the 4th century Corinthian pottery had almost entirely ceased in production.
The aryballos was another type of oil flask, although the term is a modern label for the shape. In antiquity it would have been known by other names also, such as lekythos. The shape was popular in Corinth, from which it originated, but use spread throughout Ancient Greece. It was used extensively by athletes, carried at the waist to transport oil for the gymnasium.
