From the studio room he could see a field of wheat, enclosed by a wall. Beyond that were the mountains from Arles. During his stay at the asylum he made about twelve paintings of the view of the enclosed wheat field and distant mountains.[1] In May Van Gogh wrote to Theo, "Through the iron-barred window I see a square field of wheat in an enclosure, a perspective like Van Goyen, above which I see the morning sun rising in all its glory."[2] The stone wall, like a picture frame, helped to display the changing colors of the wheat field.[3]
