Van Gogh had no recollection of the event, suggesting that he may have suffered an acute mental breakdown. The hospital diagnosis was "acute mania with generalised delirium", and within a few days the local police ordered that he be placed in hospital care. Gauguin immediately notified Theo, who on 24 December had proposed marriage to his old friend Andries Bonger's sister Johanna. That evening Theo rushed to the station to board a night train to Arles. He arrived on Christmas Day and comforted Vincent, who seemed to be semi-lucid. That evening he left Arles for the return trip to Paris.
In preparation for Gauguin's visit, Van Gogh bought two beds on advice from the station's postal supervisor Joseph Roulin, whose portrait he painted. On 17 September he spent his first night in the still sparsely furnished Yellow House. When Gauguin consented to work and live in Arles with him, Van Gogh started to work on the Décoration for the Yellow House, probably the most ambitious effort he ever undertook. He completed two chair paintings: Van Gogh's Chair and Gauguin's Chair.
Van Gogh painted several landscapes with flowers, including roses, lilacs, irises, and sunflowers. Some reflect his interests in the language of colour, and also in Japanese ukiyo-e. There are two series of dying sunflowers. The first was painted in Paris in 1887 and shows flowers lying on the ground. The second set was completed a year later in Arles, and is of bouquets in a vase positioned in early morning light. Both are built from thickly layered paintwork, which, according to the London National Gallery, evoke the "texture of the seed-heads".
On January 27, 2013, at the age of 87, Van Dyke received the 2013 Screen Actors Guild Life Achievement Award. During his acceptance speech, Van Dyke reminisced about his work over the years as an entertainer and stated that his career has "been full of surprises and a lot of fun." He also praised actors working in the industry today, calling them "the greatest generation of actors" and telling them, "You've all lifted the art to another place now." He continued with a rhetorical question for his Hollywood colleagues: "Aren't we lucky to have found a line of work that doesn't require growing up? I love that." Van Dyke is the 49th recipient of the SAG Life Achievement Award, following 2012 honoree Mary Tyler Moore.
