Reconstruction of 10th century grave bj 716 from Birka, Sweden. The pale green is easy to get, an old Icelandic dyeing recipe calls for wrapping nettles in the fabric and boiling it in a copper kettle so that the pots green patina helps deepen the green colour. The colour of the pants can be obtained with madder. Not sure about his cap. The amount of metal on his belt is to be expected since Birka was a trading settlement and a pretty wealthy one.
