The pose is apparently based on one of the Niobids in the famous Hellenistic group in the Uffizi Gallery, Florence. Richard Wilson (1713–1782) used the group in his famous painting of The Destruction of the Children of Niobe, exhibited at the Society of Artists in 1760 and published by John Boydell as an engraving by William Woollett in 1761; Turner seems to have borrowed a figure from this work for his own picture of The Destruction of Sodom, possibly exhibited in 1805 (Tate N00474);1 see the study in the Calais Pier sketchbook (Tate D04932; Turner Bequest LXXXI 31).
There is an offset of this drawing on Tate D00198 (Turner Bequest XVIII C).
