Abstract

The archaeomagnetic study focuses on two kilns, unearthed in the lower city of Cumae, a the kiln in the necropolis of the Median Gate and a pottery kiln at the Cava greca. The two kilns are dated between the 5th and the 7th century AD by the stratigraphy and the typochronology. Archaeomagnetic samples, cored in the bricks of the kiln walls, were analyzed by thermal demagnetization and by the Thellier-Thellier protocol. The two kilns provide very good archaeointensity results and the directions of the thermoremanent magnetization are well grouped. The significant difference between the two mean archaeointensities indicates that the last use of the two kilns were not contemporaneous. Archaeomagnetic dating is performed with the predictions at Cumae of the European model of the geomagnetic field SCHA.DIF.3k. The kiln from the Cava greca is dated between 590 and 640 AD at 95 per cent of confidence. At the same confidence level, the kiln FR59006 from the necropolis of the "Median Gate" is dated between 540 and 645 AD. The second half of the 6th century appears the most probable dating. These two archaeomagnetic datings concur and precise the archaeological dating. Our results date the use of the workshops in the Byzantine period and document the medieval changes of the antique city.
