The Dutch painter Rembrandt van Rijn (1606–1669) left behind the largest collection of self-portraits in the history of art. Although about 40 of his oil paintings could be considered “self-portraits,” controversy still exists regarding 14 of them. We undertook to determine the identity of the painter or the subject. Our work was based on the generally accepted premise that these portraits represent a “realistic” rendering of the subject. Self-portraits on which there is consensus regarding the authenticity were chosen as the basis for our measurements. Using a computerized technique we measured the brow ptosis. We also subjectively analyzed Rembrandt's facial aging and the unique asymmetrical elements in his face. We could not add any useful information on 6 of the 14 portraits and suggest that 8 should be considered authentic. Facial aging analysis and the unique surface anatomy allowed us to confirm Rembrandt as the painter in four of six self-portraits. We confirmed Rembrandt as the subject and painter in three more paintings. Of the two paintings in which the subject’s identity was controversial, we determined Rembrandt as the subject in one. We were able to date Rembrandt’s age in two other works and considered another portrait to be a copy. Our methodology may serve as an additional tool for the authentication of self-portraits.
 

Background: Due to the absence of accurate tools and appropriate photographic material there is a paucity of objective studies on facial aging in the modern literature.

Objectives: To measure changes in two elements of the face: brow ptosis and cheek mass migration, using an objective tool that we developed, which we then used to evaluate facial aging in two subjects, studying serial professional photographs over a 25 year period.

Methods: We studied the photographic atlas of the "Brown Sisters," a record of the yearly group photograph of four sisters, taken by the photographer Nicolas Nixon. For technical reasons, only two of the sisters fulfilled the criteria we set for the study. We used the interpupillary distance of each photograph studied to standardize the brow height and cheek mass distance from the interpupillary line.

Results: We observed progressive medial brow descent occurring at about the age of 30, with apparent stabilization thereafter. In contrast, there was a continuous process of lateral brow descent through the years. A process of gradual cheek mass descent was noted in the second half of the third decade.

Conclusions: Our results indicate that the dynamic brow changes start in the second half of the third decade, with more significant lateral brow descent than medial brow descent. The cheek mass reflective point moves in an inferior-lateral direction. The tool we developed can be used to follow aging changes and postoperative results, thereby helping the surgeon achieve true rejuvenation surgery.
