The Virgin Mary is dressed as the Queen of Heaven, wearing a crown and carrying a sceptre. She stands on a crescent moon, her left foot resting on the head of a serpent with an apple in its mouth. The infant Jesus sits on her right arm and rests his arm on her shoulder; he has a cross on his tunic. Beside the Virgin stands a bishop-saint with a mitre, holding in his left hand a pastoral staff which rests against an open book. With his right hand he points to the Virgin. They stand on a plain with distant mountains. The sky is delicately modelled with rays and clouds. Ambrose is generally shown in bishop’s robes with a mitre and crozier though his attributes, a swarm of bees or a scourge do not feature here. For commentary on the German source of this panel, see SG103. Popham noted ‘Rubens influence’.

In England there is a related pair of saints, St Peter and St Margaret, at the Church of the Holy Trinity, Berwick on Tweed, while two further related panels, St Francis and St Dominic and St Joseph and the Christ Child, are in the Chantry Chapel of Farleigh Hungerford Castle (Somerset).
