This anthology brings together the few essays on Lumia that were published during Thomas Wilfred's lifetime. Wilfred, an artist who experimented with a form of visual music he called "Lumia" developed an entire aesthetic system that could either be performed live, or set-up as an automatic display. His instrument, the Clavilux, was subject of several patents, collected along with images from Opus 161. Together these essays, the patents, and selected images provide a clear description of Lumia, what Wilfred described as "the eighth art."
