The representation of the Holy Trinity is one of those that were often painted and whose working drawings have been preserved. It is inspired by the interpretation of Psalm 109:1, so that God the Father is shown in the image of Christ the of Days, God the Son in the image of Christ Pantokrator and the Holy Spirit in the form of a dove, indicating that the Logos, incarnated on earth, sits at the same time at the “right hand” of the Father on throne in heaven and that is why it is called Synthronoi, i.e. Throne. The composition was widespread from the end of the 14th century.
The way of depicting the three faces of God in one painting has occupied theologians and iconographers since the earliest days of Christianity, in connection with the interpretation of the unity of the Trinity in the Symbol of Faith. Disagreements on these and other issues finally led to the Schism in 1054.
