In early medieval painting the traditional themes of Greek and roman are were replaced by painting?

In early medieval painting, traditional themes of Greek and Roman art, which often focused on Humanism, mythology, and idealized forms, were largely replaced by Christian themes. Artists emphasized religious subjects, such as Biblical narratives and saints, reflecting the spiritual focus of the era. This shift also led to a more symbolic and abstract style, moving away from the naturalism of classical art. As a result, early medieval paintings often served as didactic tools for religious instruction rather than mere aesthetic expressions.
