The Trinity Icon
Stuart Munro-Hay writes in
A theme often occupying an important place un manuscripts or wallpaintings- over the sanctuary door – is the Trinity represented as three equal beings, generally three old men. This style of representation for the Trinity was forbidden in Europe after the prohibition of Benedict XIV in a Constitution of October ., 1745, but it is still current in
A square wooden picture, which had three figures all one measure of equality and age, as they are ab eterno. And in each of the corners, to wit, in the bottom right-hand one, was a lion, and above, an eagle, and in the other, an ox, and above, the figure of a man, whence he knew it was the Trinity, and the four Evangelists who affirmed it, for Ezekiel saw them in those shapes, as he says in the first chapter, and likewise Saint John in the fourth chapter of the Apocalypse.
