the first systematic classification of amphorae types was undertaken by the german scholar heinrich dressel. following the exceptional amphorae deposit uncovered in rome in castro pretorio at the end of the 1800s, he collected almost 200 inscriptions from amphorae and included them in the ". in his studies of the amphorae deposit he was the first one to elaborate a classification of types, the so-called dressel table, which is still used today for many types. subsequent studies on roman amphorae have produced more detailed classifications which are usually named after the scholar who studied them. for the neo-phoenician types see the work by maña published in 1951, and the revised classification by van der werff in 1977–1978. the gallic amphorae have been studied by laubenheimer in a study published in 1989, whereas the cretan amphorae have been analyzed by marangou-lerat. beltràn studied the spanish types in 1970. adriatic types have been studied by lamboglia in 1955. for a general analysis of the western mediterranean types see panella, and peacock and williams.
