I have recently seen a number of Gospel Covers differing from those I have been accustomed to seeing and this has peaked my curiousity about the rules and traditions shaping what is found on the covers.
Would anyone be able to point me in the right direction on this - are there formal rules or canons around what is and is not depicted on the gospel covers.
What I am accustomed to seeing is:
Front Cover: Resurrection with 4 Evangelists in the corners
Back Cover: Crucifix with or without the 4 Prophets in the corners (David, Solomon, Isaiah & Jeremiah or Moses is what I have seen)
Any insights as to why prophets are depicted with the Cross, while the Evangelists are shown with the Resurrection?
And why are these prophets depicted in connection to the Gospel book beyond their simple prominence among the prophets?
Why not the four major prophets are generally identified as Isaiah, Jeremiah, Ezekiel & Daniel - or is this a foreign modern biblical scholarship idea?
Also, I have seen a number of variants - particularly with the back cover of the gospel:
Mother of God
To a lesser extent I have also some variants on the front covers:
Christ as Teacher
Ascension or some form of Christ in Glory
How do these variants fit or depart from the traditions regarding Gospel Covers?
I look forward to hearing any thoughts or insights.
