In the late 1980s American artist Peter Erskine created a new solar spectrum environmental art medium called “Secrets of the Sun)” in which he transform Interior spaces with laser-cut prism Installations. 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. He says the intent of his light installations is to use “the emotional impact of art to address the full range of nature from its most elemental expression as pure light to its most complex expression as global ecology.” You can explore more of his work with light over the last 30 years on his website.
