You may not know his name, but if you’ve spent any time wandering around South Street, you’re familiar with his work. Since the 60s, mosaic mural artist Isaiah Zagar has been reimagining the city’s streets, tiling every wall he can with shards of glass and broken bits of reclaimed and handmade tiles. But his magnum opus, a mixed-media labyrinth built from a blend of dumpster-dive finds, handmade art and donated materials, proves that one man’s trash truly is another man’s treasure. Covering nearly half a city block of multilevel space, walking around the gardens feels like walking in a dream. Empty wine bottles glow emerald, miniature rainbows leap from mirrored shards and onto the pavement, and bicycle wheels remain forever encased in cement archways. Tin angels reside next to devil masks, and bits of poetry punctuate the structure, lending a window into the mind, and the madness, of the artist.
