A couple of days ago I mentioned the new Maximinus Thrax exhibtion at the Braunschweigische Landesmuseum devoted to the battle that took place around AD235 between the Romans under Maximinus Thrax and the Germans on the Harzhorn, near Kalefeld. It is called: "Roms vergessener Feldzug. Die Schlacht am Harzhorn".
No new stand out articles yet, but there is a good radio piece on Deutschlandradio Kultur. You can hear it here and there are various download options. As a recap, note too the previous radio feature on the battle in September last year. I blogged it here.
