Very little is known about the life of Matthias Grünewald, a painter (German Maler) who worked in the early decades of the 16th Century in Germany. He is renowned for the pictures he created between 1512 and 1516 for the altarpiece of the Monastery of Saint Anthony in Isenheim in southern Alsace. The face of Saint Sebastian in one of these paintings (above) is considered to be a self-portrait.
