61/8 x 81/4" (155 x 210mm).
As noted by Jap Bolten, the present drawing is a copy of a Bloemaert drawing in Dresden at the Kupferstich-Kabinett, inv. # C 1980-70.1 Bolton had previously catalogued the Dresden sheet in 2007 but with a different subject designation. He no longer thinks it is a Banquet of the Gods or the Marriage Feast of Peleus and Thetis, prefering his present identification as a depiction of The Sinful Ways of Mankind before the Flood. 2
Judging by the illustrations, the original drawing is darker with richer washes than the present drawing. However, in actuality, who knows. What is clear, given that the dimensions are correct, is that despite both drawings being cut down and yet showing the same of the composition, ours is a bit larger, especially in the height. Our drawing is more schematic and less specific in the morphology of the figures.
