NH lists nine states, of which the first five by Rembrandt. The 6th (two dots and cross) and 7th state are ‘new’. Most other authors list six states, Nowell-Usticke two trial prints and six states.
In the 1st state (NH, WB, R743/NU trial print A) the plate is still square and has square corners (250 x 187 mm). The picture itself is almost oval. The collar is almost white. The background is a curtain to the left only.
In the 2nd state (NH, WB, R744-745/NU trial print B) the shading on the collar is completed. Shading is also added to the cap and to the face (the eyes), hair and beard.
In the 3rd state (NH, WB, R746/1st state NU) the plate is cut to an octagon and heavily reworked. The dark background is added. The signature, date and inscription are added. A smaller book is placed on top of the first. The oval form is very weak at the right side, but this is due to cutting the print incorrectly (HD).
In the 4th state (NH, WB, R747/2nd state NU) the oval shape is strengthened. In the curtains, especially the right one, close horizontal lines are added. The right and left lower corners are irregular.
In the 5th state (NH, WB, R748/3rd state NU) the corners are corrected.
In the 6th state (NH only) an anonymous owner added a cross in the lower left corner and two dots behind the date in the upper right corner (one dot already present, JM).
In the 7th state (NH only) the plate is extensively reworked. The darker folds of the curtain, the cap of the sitter, the shadows behind him and on his arm and in many more places. Some lines now cross the oval contours, like under the signature, under the table and under the books. Many lines on the ruffed collar are redrawn, as are the signature and the date. In the 8th state (NH/6th state WB (final), R749/4th state NU, Watelet, P.Basan) the plate is lightly and expertly retouched (possibly by Watelet) with many very thin lines of shadow. Such as horizontal lines on the bust directly under the collar. There are parallel lines under and on the nose and vertical shading near the top right of the column. Later impressions still show some burr. In the 5th state (NU H.Basan, Jean) thick shading is added to the background. There is much new work on the curtains on the right.
In the 9th state (NH/6th state NU, Bernard, Beaumont) the entire plate is rebitten. The vertical shading on the nose is relatively heavy. The hat is strongly reworked, visible in the highlight on the right side of the band.
