12. This postscript seems to be a reaction to a remark made by Theo, who had become acquainted – through a colleague at Goupil’s – with
Victor Horta. Horta, who later gained renown as an architect, had gone to live in Brussels in 1880. See Victor Horta,
Mémoires. Ed. C. Dulière. Brussels 1985, pp. 7-8, 316; and
Horta. Van Art Nouveau tot Modernisme. Ed. Françoise Aubry and Jos Vandenbreeden. Ghent 1997, p. 225. Horta’s memoirs do not tell us whether Vincent actually paid him a visit.
