What is Norman–Arab–Byzantine culture?

The term Norman–Arab–Byzantine culture, Norman-Sicilian culture or, less inclusively, Norman–Arab culture, refers to the interaction of the Norman, Latin, Arab and Byzantine Greek cultures following the Norman conquest of Sicily and of Norman Africa from 1061 to around 1250. The civilization resulted from numerous exchanges in the cultural and scientific fields, based on the tolerance shown by the Normans towards the Greek-speaking populations and the Muslim settlers. As a result, Sicily under the Normans became a crossroad for the interaction between the Norman and Latin Catholic, Byzantine–Orthodox and Arab–Islamic cultures.
