Since the 1960's American artist James Turrell has been working with phenomena related to light and perception. He is well-known for his extensive work at Roden Crater in Northern Arizona. For the eclipse of the sun in August of 1999, Turrell built two temporary structures--both in England--that would serve as receptacles for the reflections of the sun's activity during the brief 2 minute period of the eclipse. Subsequently dismantled, this book is an important record of the installations, and includes an audio CD related to the installations.
