In early medieval painting, traditional themes of Greek and Roman art were largely replaced by religious subjects, particularly those centered on Christianity. Artists focused on biblical narratives, saints, and symbols, using visual storytelling to convey spiritual messages. This shift reflected the growing influence of the Church and the desire to educate the largely illiterate population about Christian beliefs and values. Additionally, the style became more symbolic and less concerned with realism, emphasizing spiritual rather than physical beauty.
