The subject is taken from the Book of Tobit in the Old Testament Apocrypha. The blind Tobit sent his son Tobias out to collect some money; the boy was accompanied by the Archangel Raphael in disguise. Raphael helped him to catch a fish, the heart, liver & gall of which were used by Tobias to drive away a demon & cure his father's blindness. Here the boy & angel are shown travelling together, the fish being dragged between them. The flowers in the foreground are cabbage poppies, & in the middle ground is a herd of cows. The painting has been executed on a copper plate engraved with a coat of arms. The painting appears to be based on a much imitated composition by Elsheimer.
