This devotional painting illustrates an Old Testament story (Tobias 6, 1-8) in which Tobias meets the Archangel Raphael. The story of the two Tobias, father and son, is a model of Jewish piety and the father foreshadows the suffering of Christ´s Passion. He was faithful to the Law of God in the midst of generalized abuse and was put to the test on various occasions, always successfully. This scene depicts one of those events, when he went blind and God sent the Archangel Raphael to tell his son that his father could be cured by applying fish liver to his eyes. Notable here is the use of light as the most important technical element. The Archangel´s brilliance is, in fact, the only source of light in the whole composition.
