 When an artist paints a scene on two or more surfaces, we call it a polyptych. A "diptych" is a two-part work of art; a "triptych" is a three-part work; a tetraptych or quadriptych has four parts; pentaptych five; hexaptych six; heptaptych seven; octaptych eight parts; enneaptych nine; and decaptych has ten parts.
