The most important indication of when this letter was written is the remark ‘If you can, send a Carte de visite to Ma on her birthday’
(l. 263). This implies that the letter was written at least two days before Mrs van Gogh’s birthday on 10 September, i.e. on Friday, 8 September at the latest. Vincent’s request that Theo send ‘that page from Michelet’
(l. 34) seems to be a repetition of the question posed in
letter 89 (ll. 251-253). Thus the present letter, which was most likely written around the beginning of September, is here dated to between about Saturday, 2 and Friday, 8 September 1876.
