The document discusses several early Christian artworks from the 6th century, including mosaics from the Church of Sant'Apollinare Nuovo in Ravenna and illuminated manuscripts like the Rossano Gospels. The artworks combined Christian religious imagery with motifs from classical Roman art, using symbolism and narrative images to convey biblical stories. Materials like ivory, gold, and parchment were common supports and helped reinforce the sacred nature of the images during the rise of Christianity in the Byzantine Empire.
