The waterfall at Forestay is famous as the backdrop for Duchamp’s final work, Etant donnes. But as yet, little formal research has been done on just why the artist picked this particular bit of landscape and what it means. (As the subtitle indicates, the two "given" premises of the work are "the waterfall" and "the illuminating gas.")

An upcoming symposium at Forestay aims to fill the gap with lectures and an exhibition of relatively rare Duchampiania, as well as a concert of the artist’s "Musical Erratum."

(Opening May 7; events continue through June 13.)
