The earlier part of the provenance given above is suggested by Essick on the basis of the faint offset from plate 1 of Blake's The Ghost of Abel published in 1822.
The subject, from Bunyan's Pilgrim's Progress, was first identified by William Michael Rossetti ('Engravings' in A. Gilchrist, The Life of William Blake, London, 1863, vol. II, p. 258): in Bunyan's text the dust, which was first swept and 'began so abundantly to fly about' and was then settled by sprinkling water, typifies Man's sins, disturbed by the Law but settled by the Gospel. Blake shows the Law as an old man with bat-like wings and the Gospel as Bunyan's Damsel; the small figures are presumably the sins.
This is an example of the second state of the print, dateable to circa 1821-2 by the 1821 watermarks on three of the other known impressions. The work has been variously described as a 'woodcut on copper', a 'relief-etching and white-line engraving' and a 'woodcut on pewter'; Essick remains undecided (op. cit., p. 110; his account on pp. 102-110, with illustrations, is the fullest on the states, dating, technique and subject of this work).
