Plate B57, twin of B55, also comes from the Monastery of Santa Maria Teodote or della Pusterla, the current Episcopal Seminary of Pavia. The slab, decorated in the style of the lutprandean renaissance (712-44), has a decorative motif in a band composed of vegetable spirals, depicting images of bunches of grapes and birds, as well as a twelve-petal rosette. In the central field two peacocks appear in heraldic position drinking from a cantharos (surmounted by a cross) with handles, on the sides of which there are a flower and a disk with concentric circles. It is significant that of the two pictorial layers brought to light by the excavations of the monastic church, the oldest is a velum with painted figures of animals, among which that of a peacock stands out. In this way it is ideally possible to reconnect the two slabs to a more complex decorative program through the use of decorative elements taken from the ornamental repertoire of the Lombard sculptural tradition of the eighth century.
