Animals are very common subject in mosaics, but the early Cristian mosaics of Aquileia are not merely decorative.
The significance of a mosaic showing a fight between a rooster and a tortoise has been debated at length. The prevalent opinion is that the rooster is the symbol of the light of a new day, thus representing Christ, the "light of the world”. The tortoise, whose Greek name means "dweller of the darkness" is the symbol of the Evil. #mondayinspiration at Basilica Patriarcale di Aquileia
