“A new collection of Vincent van Gogh’s letters casts doubt on the popular notion that his mental illness was also the source of his artistic genius. A curator at the Van Gogh Museum in Amsterdam, Leo Jansen, and two Dutch colleagues are working on a complete annotated edition of the artist’s more than 800 extant letters. The new edition will also include around 2,000 illustrations, artwork by van Gogh himself and by other artists that he refers to in his letters.”
