The collaboration of the two artists is documented by Houbraken (A. Houbraken, De groote schouburgh der Nederlantsche konstschilders en schilderessen, I, Amsterdam, 1718, p. 130) and dated landscapes by Keirincx with figures by Poelenburgh are known from 1631 (Bayerische Staatsgemäldesammlungen, Munich) and 1633 (Kunstmuseum, Bremen; see P. Sutton, catalogue of the exhibition, Masters of 17th Century Dutch Landscape Painting, Amsterdam, Boston and Philadelphia, 1987-8, p. 362). The present picture would seem on stylistic grounds to be of later date and may well have been painted in 1639-41 while both artists were living in London. There King Charles I rented in July 1639 a studio in Orchard Street, Westminster 'for the use & dwellings of Cornelius van Pollenburgh and Alexander Keyrinx two Dutchmen' (J. Harris, The Artist and the Country House, London, 1979, p. 27)
