"... painted in July 1889, when he was trying to recuperate at the hospital of Saint-Paulde-Mausole in the town of Saint-Rémy, not far from Arles. The painting represents the Alpilles, a low range of mountains visible from the hospital grounds. In it, he activated the terrain and sky with the heavy impasto and forceful, broad brushstrokes characteristic of his late work."
