The Central pinnacle
This section is missing. General opinion is that it featured
the Ascension of Christ, with Christ in glory above. Using
work by different artists, I've tried to suggest some idea of what this
section may have looked like.
An alternative suggestion is that the panel would be topped
with an image of God the Father. This could apply to both back and front
of the Maesta.
