This is a great image of jugs from a well group:
The excavator dates the deposit to the "late 4th/early 5th AD." Similar pieces to the "gouged" jugs in the lower two rows are published from Agora V group M, e.g. agathe.gr:P+22011. Such "oblique gouging" continues into the 6th century, when Attic jugs of this type are available in Corinth (Slane and Sanders 2005:no. 2-16).
