The portrait of a young lady on the cusp of maturity shows her with the fashionable costume and hairstyle of a Milanese court lady in the 1490s. By process of elimination involving the inner group of young Sforza women, Kemp concluded that she is probably Bianca Sforza, the illegitimate (but later legitimized) daughter of Ludovico Sforza ("Il Moro"), duke of Milan. In 1496, when Bianca was no more than 13, she was married to Galeazzo Sanseverino, captain of the duke’s Milanese forces. Galeazzo was a patron of Leonardo. Tragically, Bianca was dead within months of her marriage, suffering from a stomach complaint (possibly an ectopic pregnancy). Milanese princesses were the dedicatees of books of poetry on vellum: such a portrait of a "beloved lady" would have made a suitable frontispiece

 or main illustration for a set of verses produced on the occasion of her marriage or death (most probably the latter).

The physical and scientific evidence from multispectral analysis and first-hand study of La Bella Principessa may be summarized as follows:
  • The technique of the portrait is black, red and white chalks (trois crayons
    Trois crayons

     drawing of A Woman in Profile, which, like other head studies by Leonardo, features comparable delicate pentimenti to the profile.
  • The members of the Sforza family were always portrayed in profile, whereas Ludovico’s mistresses were not.
  • The proportions of the head and face reflect the rules that Leonardo articulated in his notebooks.
  • The interlace

    In the visual arts, interlace is a decorative element found in medieval art.

  • The portrait was executed on vellum—unknown in the surviving work of Leonardo—though we know from his writings that he was interested in the French technique of dry colouring on parchment (vellum). He specifically noted that he should ask the French artist, Jean Perréal

  • The vellum bears a fingerprint near the upper left edge, which features a distinctive "island" ridge and closely matches a fingerprint in the unfinished St Jerome by Leonardo. It also includes a palmprint in the chalk pigment on the neck of the sitter, which is characteristic of Leonardo's technique.
  • The green of the sitter’s costume was originally obtained with a simple diffusion of black chalk applied on top of the yellowish tone of the vellum support.
  • The nuances of the flesh tints were also achieved by exploiting the tone of the vellum and allowing it to show through the transparent media.
  • There are noteworthy similarities between La Bella and the portrait of Cecilia Gallerani

    , including the handling of the eyes, the modelling of flesh tones using the palm of the hand, the intricacy of the patterns of the knotwork ornament and the treatment of the contours.
  • The now somewhat pale original hatching in pen and ink was retouched in ink in a later restoration, which is far less fluid, precise and rhythmic.
  • There have been some diplomatic re-touchings over the years, most extensively in the costume and headdress, but the restoration has not affected the expression and physiognomy of the face to a significant degree, and has not seriously affected the overall impact of the portrait.

Disagreement with attribution

A number of Leonardo experts have concurred with Kemps's conclusions, including Carlo Pedretti, Nicholas Turner, Alessandro Vezzosi, who is the director of the Museo Ideale Leonardo Da Vinci in Vinci, Italy, Dr. Christina Geddo, Dr. Claudio Strinati of the Italian Ministry of Culture, and Mina Gregori, professor emerita at the University of Florence

 prior to the 20th century – unusual given Leonardo's renown dating from his own lifetime, as well as the fame of the purported subject's family – and the fact that vellum lasts for centuries, which would facilitate a forger's acquisition of old sheets. Further, there exist around 4,000 drawings by Leonardo, none of which feature vellum as a surface. Leonardo scholar Pietro C. Marani discounts the significance of the drawing being made by a left-handed artist, noting that imitators of Leonardo's work have emulated this characteristic in the past. Marani is also troubled by the vellum surface, 'monotonous' detail, use of colored pigments in specific areas, lack of craquelure
Craquelure
In art, craquelure is the fine pattern of dense "cracking" formed on the surface of paintings, in particular due to the aging of paints. It is often used to determine the age of paintings and to detect art forgery, as craquelure is a hard-to-forge signature of authenticity.-Authentic:Authentic...
