Dimicator

I’m Roland Warzecha — professional illustrator and swordsman. The name Dimicator comes from the Latin for “sword fighter.” I share cutting-edge research into historical martial arts, focusing in particular on Viking and high medieval sword-and-shield combat. My work is carried out in collaboration with museums, fellow martial artists, and scholars around the world.
