The top-right scene shows part of the legend of Joseph. Legend tells that he brought Christianity to England. He came with the Holy Grail and established the first English church, at Glastonbury. The picture shows Joseph at Glastonbury, having left his staff in the ground while he slept. The next morning it began to sprout and grew to become the famous Glastonbury Thorn. His staff is shown with growing shoots, with a blossoming thorn tree.
