See that you despise not one of these little ones: for I say to you, that their angels in heaven always see the face of my Father who is in heaven. – Matthew 18:10
Traditional Christians have believed that each person has an angel commissioned to guard him or her from spiritual harm. The idea is based on the verse quoted above as well as a number of other scriptural texts. It is also found in commentaries by Jerome, Aquinas, and others.1
Artistic representations of this idea became popular in the 17th century and continue to this day. Typically, an angel directs a boy along a narrow and hazardous path, as in the first picture at right. In later examples a girl is added and the path becomes a bridge. A related image type has the guardian angel conducting his charge's soul to Heaven after death, as in the second picture at right. The perils against which the angel guards are pictured in the lower reaches of the second and third pictures at right, where souls in Purgatory beg for attention.
DISTINGUISHING THE GUARDIAN ANGEL FROM THE ARCHANGEL RAPHAEL
Images of a guardian angel with his young boy are often hard to distinguish from those of St. Raphael with Tobias. In the latter, one will likely see the fish that will be used to cure Tobit's blindness, held on a string by either Raphael or Tobias. Raphael will usually have something that identifies him as a traveler, such as a broad hat and a staff with a gourd hanging from it. Guardian-angel images usually lack these features. The angel's garb will be more like that of angels generally, and there will be no fish. The boy will be wearing ragged peasant clothes, unlike Tobias's middle-class garments, and he will look younger than Tobias usually does. The terrain is also distinctive: Tobias and Raphael walk along relatively easy paths.
That said, it is clear that some artists have knowingly or unknowingly confused the two traditions. For example, the base of a statuette in St. Mark's, Venice portrays souls in Purgatory, as in guardian-angel images, but the figures above them are clearly Raphael and Tobias. And in Piazzetta's painting of an angel greeting Anthony of Padua and Louis of Toulouse, most of the iconography belongs to guardian-angel images but a pouch or gourd hangs from the angel's neck, a feature much more likely in images of St. Raphael.
It is possible that the mixing of the two traditions is not a mistake but a nod to Tobit 5:22, where Tobit reassures his wife that "the good angel of God doth accompany" their son on his journey. Tobit does not know that the person accompanying Tobias is actually an angel, so a Christian could think of this "good angel" as his son's guardian angel.
