From around the Roman empire, vessels of oil (and fish paste?) arrived here as taxes. The vessels were unsealed, emptied, smashed and stacked. The mountain (well, hill) still remains, from the ancient dump. A german archaeologist (Dressel) classified the various types of pots by their shapes and sizes; those on this mountain are all Dressel 22's. In engravings, restaurants are often shown with this pot leaning in the back, storing oil.
