Kostyrko's picture is devoted to the painter whose works carry a made-up name. How come the author whose works are more powerful and expressive than Durer's opuses was forgotten? The reason for a historical misunderstanding was a wrong ascription of the works of this unknown painter by German art critic Joachim von Sandrart. He was the first to talk about Mathis GothardtNithardt's oeuvre and by mistake called him by the name of the painter that never existed, that is Matthias Grunewald.
