During the years 1989 through 1992, german Peter Erskine, based in Santa Monica, California, created a new solar spectrum environmental art medium called “Secrets of the Sun, Millennial Meditations (SOS)”. Since then Erskine has exhibited this art in the site specific architectural installations in the USA, Italy, Germany, England and Northern Ireland. The artist’s work is firmly anchored in the architecture and context of each locality. In this art the Sun is not only the subject of the work but the medium and energy source as well.
