Like a magnet the scene in the apse will attract attention. It is the representation of the Anastasis, Greek for resurrection. It is not the resurrection of the dead, but refers to an event that is not in the New Testament, i.e.: Christ descends into the underworld of Hades and frees his forerunners, Old Testament prophets, from their captivity by Satan and binding him, ending his reign.
I have taken very many pictures of it over several years, hence a separate sub-gallery. As so often older pictures are not very true in colour, also I think restoration work may be the reason why, for instance, the colour of Eve’s dress (she is resurrected from a sarcophagus) is dark brown on some pictures, on 2016 pictures if was a brighter red.
