Dimitrios Kokotsis was a Crete-born Greek painter, who later lived and worked in Athina. Very little is known about his studies and works. His only notable known work was his participation in creating the Greek classroom at the University of Pittsburgh’s Cathedral of Learning, where 29 classrooms were designed by the ethnic groups that helped build the city of Pittsburgh. In the Greek classroom Kokotsis used the traditional encaustic painting method, employing earth colors and beeswax applied freehand which was then overlaid with 24-carat gold leaf rubbed on by polishing bones which required two men more than seven months to complete the artwork.
