Religious Tryptic

Russian wooden triptych depicting Christ the pantocrator in majesty holding The Open Book, on a stylized throne surrounded by two of the four elements of the tetramorph for the central panel.
From the Greek tetra, four and morphé, form. Representation of the four evangelists in their allegorical forms, (the man for Saint Matthew, the eagle for Saint John, the bull for Saint Luke and the lion for Saint Mark). This incarnation is inspired by the vision of Ezekiel (Ez 1, 1-14) and by the description of the four living beings of the Apocalypse according to Saint John.
The right panel represents Saint Matthew.
The left panel represents Saint John holding a parchment and a key.
It emanates a lot of softness and tranquility from their faces.
Each of the characters is draped in an antique toga and wears the halo.
