I came across this picture today. It is a rather lovely archaeological drawing of a ‘phalera’ from Seengen in the Aargau (Switzerland) showing a horseman rather like the better known one from the Isola Rizza dish. He has a helmet and armour reaching to the knees. This sort of kit is pretty well known in burials from SW Germany. I couldn’t find out anything more about the phalera. I’ll keep you posted.
