Clad in vivid ecclesiastical robes of gold and crimson, Saint Ambrose is depicted as a figure of conviction and ecclesiastical authority. With one hand raised in teaching or blessing, and the other holding a book, Ambrose stands as a symbol of sacred wisdom and liturgical influence. His stern yet thoughtful expression reflects his role in shaping early Church doctrine and resisting imperial interference. The panel's vertical composition and richly colored drapery reflect Renaissance influences, highlighting both the intellectual and spiritual weight of this revered bishop and Doctor of the Church.
