The mosaics covering all the internal walls of the Cappella Palatina in Palermo are particularly impressive. Those in the nave contain Latin inscriptions and display themes from the Old Testament (central aisle) and New Testament (side aisles). The story begins on the south wall of the central aisle and continues in a clockwise direction, thus: South wall, top row (from left to right): The Story of the Creation up to the Birth of Eve, North wall, top row: The Fall of Man to the Building of Noah's Ark, South wall, bottom row: The Dove and the Arc to the story of Abraham and the Three Angels, North side, bottom row: Lot and the People of Sodom to Jacob's Struggle with the Angel.
In the right side-aisle are scenes showing Paul and Peter, and in the left aisle similar ones of Peter.
While the mosaics in the nave tell a continuing story, those in the dome of the sanctuary center on Christ Himself; he is shown as the focal point of the religious world, the Pantokrator (Almighty Ruler), surrounded by a Greek inscription describing Heaven as His footstool. Below Him can be seen angels and archangels, prophets and kings of old Israel, with the Apostles in the four corner niches - all in accordance with Byzantine custom and that of the Eastern Orthodox Church.
Deviating from this custom, Christ appears a second time in the hemispherical dome of the main apse, with the Virgin Mary below. These mosaics are 18th century - the difference in style and quality between these and those of the 12th century is striking indeed!
Also in the chancel will be found New Testament themes such as the Annunciation, the birth of Jesus, the Flight to Egypt, the Baptism, the Transfiguration, the Ascension and Pentecost (the Crucifixion is missing).
