The woman depicted is in the center of the canvas, her face of penetrating intensity shortened by three quarters and turned with a confident gaze to the observer. A red rose, on the side of the face, highlights the diaphanous complexion. The right hand rests on the basin of a basin of a Baroque fountain supported by a triton. The left hand, dropped to the side, holds a closed fan. The sumptuous robe that wraps the figure is part of a complex Spanish-style dress, the hair is pulled back and gathered in a chignon wrapped in a crown of diamonds and a bundle of black feathers. The woman is Caterina Balbi Durazzo painted by the twenty-five-year-old Van Dyck, capable of bringing out the essential qualities of the portrayed character, proving that she has already assimilated the lesson of Rubens, of which he was a pupil: the lady retains, together with elements of aristocratic distinction, a certain airy and youthful tenderness. The portrait entered the palace in 1689 and has never left the residence in via Balbi since.
