The letter must date from after
letter 630 of 23 June in which Van Gogh is still complaining about the rain, and before
letter 634 of about 28 June in which he writes that he worked on the sower yesterday and today. This sower – an important subject to him – is not mentioned in the present letter. The remark ‘The wheatfields – that has been an opportunity to work’
(l. 116), and the fact that he told Bernard on 27 June (
letter 633, l. 65) ‘I have seven studies of wheatfields’ also place the letter in the last week of June. This is borne out by his statement that he bought his canvases ‘really not so long ago’
(l. 186) – and that was shortly before 15 June (
see letter 625) – and his request to Theo to double the order for zinc white
(l. 100) – this refers to
letter 629 of 21 June, in which Vincent asked for new paint from Tasset. For all these reasons we, like Merlhès, have dated the letter on or about Monday, 25 June 1888.
The letter has given rise to various datings. Pickvance put the date at about 16 June, but given that Van Gogh bought new canvas between 12 and 15 June and he says in the present letter that he has painted on all he has, this seems highly unlikely. Hulsker and
De brieven1990 dated it about 7 July, but it is clear from the letter that it has not yet been decided that Gauguin will go to Arles (see
ll. 79 ff. and
ll. 132 ff.), whereas this was known on 1 July (
letter 635). Dorn, finally, dated the
letter 27 June (see Hulsker 1993-1, p. 32; Dorn 1998, p. 25).
