Sicily

The heyday of mosaic making in Sicily was the age of the independent Norman kingdom in the 12th century. The Norman kings adopted the Byzantine tradition of mosaic decoration to enhance the somewhat dubious legality of their rule. Greek masters working in Sicily developed their own style, that shows the influence of Western European and Islamic artistic tendencies. Best examples of Sicilian mosaic art are the Cappella Palatina of Roger II, the Martorana church in Palermo and the cathedrals of Cefalù and Monreale.

The Cappella Palatina clearly shows evidence for blending the eastern and western styles. The dome (1142–42) and the eastern end of the church (1143–1154) were decorated with typical Byzantine mosaics i.e. Pantokrator, angels, scenes from the life of Christ. Even the inscriptions are written in Greek. The narrative scenes of the nave (Old Testament, life of Sts Peter and Paul) are resembling to the mosaics of the Old St. Peter's and St. Paul's Basilica in Rome (Latin inscriptions, 1154–66).

The Martorana church (decorated around 1143) looked originally even more Byzantine although important parts were later demolished. The dome mosaic is similar to that of the Cappella Palatina, with Christ enthroned in the middle and four bowed, elongated angels. The Greek inscriptions, decorative patterns, and evangelists in the squinches are obviously executed by the same Greek masters who worked on the Cappella Palatina. The mosaic depicting Roger II of Sicily, dressed in Byzantine imperial robes and receiving the crown by Christ, was originally in the demolished narthex together with another panel, the Theotokos with Georgios of Antiochia, the founder of the church.

In Cefalù (1148) only the high, French Gothic presbytery was covered with mosaics: the Pantokrator on the semidome of the apse and cherubim on the vault. On the walls are Latin and Greek saints, with Greek inscriptions.

The Monreale mosaics constitute the largest decoration of this kind in Italy, covering 0,75 hectares with at least 100 million glass and stone tesserae. This huge work was executed between 1176 and 1186 by the order of King William II of Sicily. The iconography of the mosaics in the presbytery is similar to Cefalu while the pictures in the nave are almost the same as the narrative scenes in the Cappella Palatina. The Martorana mosaic of Roger II blessed by Christ was repeated with the figure of King William II instead of his predecessor. Another panel shows the king offering the model of the cathedral to the Theotokos.

The Cathedral of Palermo, rebuilt by Archbishop Walter in the same time (1172–85), was also decorated with mosaics but none of these survived except the 12th-century image of Madonna del Tocco above the western portal.

The cathedral of Messina, consecrated in 1197, was also decorated with a great mosaic cycle, originally on par with Cefalù and Monreale, but heavily damaged and restored many times later. In the left apse of the same cathedral 14th-century mosaics survived, representing the Madonna and Child between Saints Agata and Lucy, the Archangels Gabriel and Michael and Queens Eleonora and Elisabetta.

Southern Italy was also part of the Norman kingdom but great mosaics did not survive in this area except the fine mosaic pavement of the Otranto Cathedral from 1166, with mosaics tied into a tree of life, mostly still preserved. The scenes depict biblical characters, warrior kings, medieval beasts, allegories of the months and working activity. Only fragments survived from the original mosaic decoration of Amalfi 's Norman Cathedral. The mosaic ambos in the churches of Ravello prove that mosaic art was widespread in Southern Italy during the 11th–13th centuries.

The palaces of the Norman kings were decorated with mosaics depicting animals and landscapes. The secular mosaics are seemingly more Eastern in character than the great religious cycles and show a strong Persian influence. The most notable examples are the Sala di Ruggero in the Palazzo dei Normanni, Palermo and the Sala della Fontana in the Zisa summer palace, both from the 12th century.
