This surreal interior scene depicts a richly decorated room with multiple distinct areas. The central focus is a bright red floor with flowing, abstract shapes. A tall arched window dominates the back wall, through which a crescent moon and floating objects can be seen against a blue night sky. To the left, a framed portrait hangs on a pink-tinted wall. The right side of the room features tropical plants and decorative wallpaper in green and yellow tones. A small red cabinet or chest sits beneath the window. The room's eclectic elements and dreamlike quality suggest a space where reality and imagination merge, fitting for a piece titled "knowledge of the ruby 7." The ornate gold baroque frame containing the artwork adds another layer of classical formality to the contemporary interior scene.
