(original Dutch: citaat van Willem Roelofs, in het Nederlands:) Maak dan die studies buiten; met de grootste eenvoudigheid, tracht u van alle zogenaamde manier te ontdoen en tracht in een woord de natuur met gevoel maar zonder denken aan het werk van anderen, na te volgen.
Quote in Roelof's letter to his pupil Hendrik W. Mesdag, 1866; as cited in Zó Hollands - Het Hollandse landschap in de Nederlandse kunst sinds 1850, Antoon Erftemeijer https://www.franshalsmuseum.nl/wp-content/uploads/2017/12/zohollands_eindversie_def_1.pdf; Frans Hals museum | De Hallen, Haarlem 2011, p. 16, note 7
