This volume comprises the stratigraphy within the plot of a bronze caster’s workshop and the surrounding alleys in the period AD 790–870. Tanks to the fine classifcation in the excavation documentation it has been possible to establish a large number of sub-levels, so that the average duration of a sub-level is around four years. This dense stratigraphy therefore enables a more accurate chronology for the manufacture of the bronze objects. This should be viewed in relation to the current methods of archaeology based on the occurrence of the objects in graves and the like, in other words, their final deposition.
