In this devotional composition, the Blessed Osanna is painted standing on the left, while invoking the Virgin Mary who appears above, surrounded by clouds, carrying Baby Jesus in her arms. Next to Osanna we see Saint Dominic, who is in turn admiring the celestial vision. The peculiarity of this painting is, however, the presence of a total of fifteen tondos on the two sides and in the upper part of the painting, depicting the Mysteries of the Rosary. On the right we have the Joyful Mysteries: Annunciation, the Visitation of Mary to saint Elizabeth, the Nativity, the Presentation of Jesus at the Temple, the Finding of Jesus in the Temple. On the left the Sorrowful Mysteries: the Agony in the Garden, the Scourging at the Pillar, the Crowning with Thorns, the Carrying of the Cross and the Crucifixion. Above the Glorious Mysteries: the Resurrection, the Ascension, the Descent of the Holy Spirit, the Assumption of Mary and the Coronation of the Virgin. Finally, it must be noted that between the Blessed and Saint Dominic, we can make out the outline of the city of Mantua seen from San Giorgio. This detail allows to identify with certainty the female figure as being the Blessed Osanna.
