These etchings are probably related to Jacques de Gheyn II's design for a grotto fountain for the Stadholder's quarters in The Hague, completed by Jacques de Gheyn III. A related drawing by de Gheyn II or III is in the Courtauld Institute, London (I.Q. van Regteren Altena, Jacques de Gheyn: Three Generations, The Hague, 1983, II, no. 531, III, fig. 446).
