As fugitives, the early Christians worshipped in secret, hiding in underground catacombs. These catacombs, where the early masses were held, therefore, bore the symbols of Christian worship which included the cross, fish, lamb, doves, grapes, and the Greek letters Alpha and Omega. Subsequently, with the regular use of these underground corridors, Christian artists decorated the walls with frescoes and mosaics of subjects surrounding the life of Christ and their own including subjects that portrayed the persecution of their like and kin. Subjects like Christ, the Holy Mother, and the saints were drawn with halos around their heads.
The Roman Empire left a legacy of Classical Art even after its decline as a "pagan" civilization having adopted Christianity as its official religion in the 4th century A.D. The Medieval Period is best explained by the overwhelming power of the Church, with the Church and Catholicism influencing every major aspect of Art and its creation. Various oriental elements enriched Christian Art; however, the overpowering intolerance of the Church and the other ideologies, including Islam, which controlled artistic output, gave the art its didactic quality. This brought us the Christian Art as we know it.
