Summary: Archaeobotanical investigations of three waterlogged sites of the migration and the early Merovingian periods throw new light on agriculture and human diet of the Germanic tribe of the Alamanni in southwestern Germany from the 3rd to the 6th century A.D. … the Alamanni cultivated the oil and fibre plants Linum usitatissimum, Papaver somniferum, Cannabis sativa, Camelina and Brassica rapa, as well as the pulses Lens culinaris and Pisum sativum.
