Cranach painted this pair of portraits in 1525, the year Martin Luther married Katharina von Bora, a former Cistercian nun who had escaped from her convent with Luther's help in 1523. Luther argued against the practice of celibacy within the church, asserting his belief in clerical marriage with his own union. A friend of Luther's and a witness at his wedding, Cranach thereafter became the principal portraitist of the couple.
Versions of these portraits exist in Basel and Stockholm.
Two round portraits. On the left is Martin Luther (1483-1546) and on the right his wife, Katharina Von Bora (1499-1552).
