Tolong jelaskan mengenai Tympanum dari Katedral Santiago de Compostela dalam bahasa melayu

The arrangement of the tympanum is based on the description of Christ that John the Evangelist makes in Revelation (Chapter 1.1 to 18). In the center, the Pantocrator is shown, with the image of Christ in Majesty, displaying in his hands and feet the wounds of crucifixion. Surrounding Christ, the tetramorph with the figures of the four Evangelists with their attributes: left, top St. John and the eagle and below St. Luke with the ox, on the right, above St. Matthew on the hood of the tax collector and below St. Mark and the lion.

On both sides of the evangelists, behind Mark and Luke, are four angels on each side with the instruments of the Passion of Christ. Some are, without touching them directly, the cross and crown of thorns (left) and lance and four nails (right), another the column in which he was whipped and the jar with which he was washed Pontius Pilate. Above the heads of these angels, two large groups of souls of the blessed, forty in all. In the archivolt of the central tympanum are seated the elders of the Apocalypse, each holding a musical instrument, as if preparing a concert in honor of God.
