These two seascapes (P1581 and P1582) are traditionally considered pendants. In the Museum`s older catalogues and inventories they are attributed to Cornelis Molenaer (ca. 1540-1589) until 1933. As of 1889, however, it is recorded that Bredius considers them originals by Simon de Vlieger (1600-1653). The highly schematic architecture in the background, the clumsy depiction of the figures and the rough representation of the waves make it more likely to be the work of a follower who, in Jan Kelch`s view, may well have been a disciple of Jan Porcellis (1583/85-1632) (Posada Kubissa, T.: Pintura holandesa en el Museo Nacional del Prado. Catálogo razonado. 2009, p. 322).
