In the National Gallery in London we also have on offer, Carlo Crivelli's, The Annunciation, with Saint Emidius, 1486, giving us the Holy birth.
Several symbolic references suggest this occurrence, for example, the peacock on the roof whose divine foliage is complemented by the seven colours of ascension in each eye of the peacock, the fruit on the ground would be about the fall, the divine dove above the Virgin Mary would be divan inspiration reading the bible, this would be attended by the divine angel with St. Anthony's divan Lily. Saint Emidius shows the divine angel the Papal Palace, more than likely, the Vatican to nominate the Holy Roman Empire. Other important reference would be the Jewish rug under a cactus bush to nominate insemination, the kind of woman's class the Virgin Mary was situated with would be suggested with the medical instruments above her head on a shelf. All the rest of the people in the background would be significant to Papal Palace life. And the building seeming a slight wrong usage of perspective would be internal geometry from the Holy divine.
