In Byzantine decoration the peacock is a common motif. In many cases, a pair of them eat grapes from a vase, often with vines growing from it. The vase shape is a kantharos, a Greek vase that was used for wine. The grapes and wine are a symbol of Christ (the wine signifying his blood), and thus the promise of salvation and the paradise that awaits the blessed. These peacocks are done in mosaic on the floor just inside the main portal of the magnificent church of San Donato on Murano in the Venetian lagoon. They date from the 12th century. All of the pavements of San Donato are done in splendid mosaics. In one scene, a fox is captured by rabbits, while in others knot designs and geometric motifs in coloured stones decorate the floor.
