Peter Erskine’s New Light on Rome (2000) via triangulationblog.com:

“Trajan’s Markets Aula and Hemicycle, House of the Knights of Rhodes, Porta di San Sebastiano, Criptoportico of Nero – stone witnesses to a bygone culture in Rome that today needs to be preserved and protected. At the dawn of the new millenium, these two thousand year old buildings are becoming a stage and a backdrop for a Solar Specturm art installation by Peter Erskine.

Erskine uses prisms and mirrors to spread white sunlight into the colors of the solar spectrum. He floods roman arches and columns with rainbows. Changing with the hours and seasons, the art is different every day of the year. The rays of the Sun, the origin of all life, create a fascinating interplay of colors and forms. Here, solar energy and monuments to human creativity unite to form a living work of art in which visitors themselves become creators and participants. We see ancient Rome in a new light.”
