The Old Testament Trinity: Hospitality of Abraham (1697-1699) by Ivan Rutkovych - Public Domain Orthodox Icon

Three angels sit at a table, the three visitors who were welcomed by Abraham at Mamre (Genesis 18) and have long been read as an image of the Holy Trinity. It is part of the Zhovkva iconostasis (1697-1699) by Ivan Rutkovych, now in the Andrey Sheptytsky National Museum in Lviv, Ukraine.
