The palm-branch is a very early symbol of Christianity; its image often accompanied martyrs to symbolize their "victory" over earthly temptations and misery. The palm was in long use by the Romans before Christianization and carried over into Christiani. The leaves of the palm also figure in the New Testament, carried by the crowd who met Jesus upon his" triumphal entry" into Jerusalem.
The lily is a symbol of purity, chastity, and simplicity. As such, it is the emblem of the Virgin Mary, and often figures in scenes of the annunciation.

The olive is symbolic of fertility and abundance, of hope and new beginnings, and, of course, peace. The olive tree is mentioned numerous times in the old testament, as olives were a staple crop for the Hebrews.

The dove returned with an olive branch, which became a symbol of peace between God and man.
The pomegranate is an ancient symbol of wisdom. In Christian art, it often represents the Church, the seeds within individual congregations.
