This work is related to 1595 Jonah, Ertz 1979 #13.
This is the most frequently copied of Jan's early compositions. Weak copy by a follower in Turin, Galleria Sabauda, Inv. #232. The following are in RKD but not mentioned by Ertz in either edition: weak copy (monogrammed JB) Amsterdam, Rijksmuseum (copper, 29.5 x 41); copy (monogrammed JB) formerly art market, Munich (Th. Stroefer, 1937) (copper, 28 x 37) -- page on wiki; copy formerly art market, Brussels (R. Chasles, 16.xii.29 #12) (copper, 28.5 x 36); copy that seems to me quite good, maybe autograph/studio, formerly private collection Milan (Prof. Gingarelli) (copper, 29 x 39)-- page on wiki; copy sold Stockholm (Bukowski) November 14/16 1965, #116 (copper, 25 x 35); copy private collection, Belgium (copper, 28 x 37).

A number of the above copies are attributed by Ertz to Josef van Bredael and published in his 2006 monograph on that artist (#s E130-E133)
