It is fitting that the Annunciation of Mary has been considered the most sublime subject of all of classical artistic composition because the subject matter is the highest expression of the paradox of the coincidence between immortality and mortality, between God and Man.

However, of all of the treatments of this subject known to me, Fra Angelico is the only artist to recognize that such a coincidence of opposites involves the divinization of mankind.
