Flowers in an Jug (verso), 1485. The jug of flowers on the reverse is one of the first independent still lifes known in art. However, this early flower composition has a religious significance as it contains symbols referring to Christ and to the Virgin. The maiolica jug has Christ¡¦s monogram on the front while the flowers refer to Mary: the lilies refer to her purity, the irises to her role as Queen of Heaven and to her role as mater dolorosa during the Passion, and the small aquilegias are associated with the Holy Spirit. The rug on which the jug is standing is of an eastern type.
