"Cassiopeia #2" exemplifies Joseph Cornell's signature shadowbox technique, combining found objects and materials into a densely layered composition that invites intimate contemplation. The assemblage of disparate elements such as driftwood, a cork ball, mirror fragments, and printed paper creates a poetic narrative that references both the celestial mythology of its namesake and Cornell's personal archive of curiosities. Through this mixed media construction, Cornell transforms humble, ordinary materials into a work that operates between scientific observation and romantic reverie, characteristic of his influential contribution to Surrealism and assemblage art.
