The inscription on the vase which contains lilies, roses (both symbols of the Virgin), pinks (a symbol of Christ’s passion) and pansies (a symbol of the Trinity) reads M (standing for 'Mater') Jhs ('Jesus') A ('Angelus' or 'Ave'). This was originally a portable altarpiece, containing a scene of the Nativity on the central panel and the Annunciation on the two panels forming the wings.
