"..he [= Vincent] often stayed talking for a while after the lesson [Greek and Latin, in Amsterdam, 1877-78], and naturally we often discussed his former profession, the art dealing business [of Goupil & Cie.] He had kept quite a number of the prints which he had collected in those days [1869-1875], little lithographs after paintings, etc. He brought them to show me repeatedly, but they were always completely spoiled; the white borders were literally covered with quotations from Thomas a Kempis and the Bible, more or less connected with the subject, which he had scrawled all over them.. ..in no way could I guess those days.. ..that in the depths of his soul lay dormant the future visionary of colour."
