The Catholic religion became divided in the Great Schism. The art period up to 1000AD is referred to as Pre-Romanesque art and after that date as Romanesque Art  

Romanesque Art History Overview
The Romanesque art style of the Dark Ages or early Medieval Religious Art was created largely for the Christian Catholic Church in the European lands which were part of the western Roman empire. Christian art and religious iconography began, about two hundred years after the death of Christ. Western Christian art and religious iconography was originally based on the classical art styles and imagery used by the Ancient Romans. In the period encompassing Medieval art iconography began to be standardised and to relate more closely to the texts found in the Bible.
