The diptych is an artists device for portraying two equally notable persons or places on two canvases in one frame because they relate so closely to each other. Diptych: Tales of Two portrays two personsDorothy St. John and Charles Thomas Milleras they developed separately in their youth. They went to Argentina together in the thirties and slept in jungle camps inside tent-cabins and cottages built by the big oil company he worked for. They merged their lives with a veritable United Nations of fellow workers and laid the foundation for lives in the civilized world that they rejoined when they went home, full of tall tales and great pictures.
