The symbol of Heaven
The dome is a symbol of Heaven, clearly telling us that Heaven has opened to Earth. The dome "speaks to us of a God who became man; that in Jesus Christ heaven and earth, God and man, have been reconciled and united through his death and resurrection, through that new creation which is Easter." The dome thus represents the vault of heaven whose center is Christ. Placing an image in a dome-shaped photoceramic thus evokes a strong connection between Christ and our deceased loved ones.
