On the right of Christ stands St. Paul (whose name is written in Greek and Latin) and St. Luke, the “biographer” of Paul who wrote the book of Acts. On Christ’s left is St. Peter and his brother St. Andrew, the first apostle called by the Lord. They stand in a field filled with flowers and little animals. In the lower register, beneath Christ is the Hetimasia, a Byzantine representation of an empty throne on which rest the instruments of the Passion. The throne is flanked by a pair of angels as well as the Apostles carrying scrolls with the text of Gloria in Excelsis in a version slightly different to that used in Mass.
