Good Friday is one of the most sacred days of the year for Christians, when the death of Jesus by crucifixion is remembered. The exact date when this happened is not known. However, the Gospel accounts make it clear that it was on a Friday and scholars, whilst disagreeing over detail, seem to point towards the year AD33 or 34.
There are representations of the crucifixion in many churches – as paintings, sculptures or in stained glass. The photograph with this post is of the stylised representation of the crucifixion in the apse window of the former East Kirk of St Nicholas.
