1. From early July to the end of September Van Rappard and his friend L.W.R. Wenckebach went on a walking tour across the Hondsrug in Drenthe. See exhib. cat. Amsterdam 1974, p. 88.
12.Shepherd with flock of sheep (F 42 / JH 517); this measures 67 x 126 cm.
13. This painted study of a wheat harvest is not known.
14. This painted study of an oxcart in winter is not known.
15. These two works must have been made after Van Rappard’s visit – which lasted from about 17 to about 27 May (letter 447) – and we can also infer that they must have been finished for some weeks, since Van Gogh is not sure whether or not he had already written to Van Rappard about them. The painting of a woman spinning must have been the same one he referred to in letters 449 ff.
The weaver he means was probably Weaver near an open window (F 24 / JH 500) or Weaver, interior with three small windows (F 37 / JH 501), which he wrote about in letters 451 and 452.
17.Charles Blanc, Grammaire des arts du dessin, architecture, sculpture, peinture. Paris 1867. We consulted the second edition (Blanc 1870). Van Gogh refers to a note in Les artistes de mon temps, where Blanc talks of the colours in Delacroix and then refers to his Grammaire (Blanc 1876, p. 65). In April 1885 Van Gogh copied out this page, including the reference, for Theo (letter 494). The Grammaire contains wide-ranging practical and theoretical information about the arts it deals with.
