This small and finely painted panel was likely part of a larger composition. The subject derives from the Book of Genesis 18 where three men visit Abraham and Sarah. Abraham addresses them as Lord and orders a feast to be prepared in their honor. In this moment, the messengers announce that a son will be born to the elderly, childless couple. Early Christian theologians understood this passage as a manifestation of the Holy Trinity.
The image of three angels, seated at a table, gained prominence in the late Byzantine period and would become a favored means of representing the Triune God—Father, Son, and Holy Spirit—in Orthodox iconography. Painted in a refined style with thin, delicate proportions, this icon is an elegant example of late Byzantine painting.
