NH lists seven states, only the first two by Rembrandt. The 3rd state, with the two dots, is ‘new’. Most other authors list three states, Biörklund four, Nowell-Usticke six. From his 3rd state there are later impressions by Watelet, P.Basan, Basan, Jean, Bernard and Beaumont.
In the 1st state (NH, WB, R738, NU) there is an easel and a picture of a landscape in the background. Some impressions show scratches to the left of the hat, according to Benesch a state between 1 and 2.
In the 2nd state (NH, WB, R739, NU) the easel and picture are burnished out, but traces are still visible in early prints. They later wear out or are burnished on purpose.
In the 3rd state (NH only) two dots are added in the upper right corner.
In the 4th state (NH/3rd state WB final, NU) the last traces of the easel are gone and dark shadows are added with fine shading in the hat and cloak. Shading is added by use of a rocker in various places, like on the upright book on the left, and the triangle thereunder and inside the contour of the cloak in the lower right corner.
In the 5th state (NH/4th state NU Watelet, P.Basan) the face is retouched, like shading added under the right eyebrow, under the right eye and along the right cheek. It seems that the pupils are smaller (JM).
In the 6th state (NH H. Basan/5th state NU Jean) there new shading right of and over the left shoulder and crosshatching in the blank space to the left of the right cheek.
In the 7th state (NH/6th state NU Bernard, Beaumont) the plate is entirely reworked. A new highlight appears on the hat.
