This accumulation of open structures signifies a revival of seriality in LeWitt's work, inspired by the serial photographs of Eadweard Muybridge, whose work LeWitt discovered in an abandoned book a previous tenant had left in his apartment. The network of cubes allowed LeWitt to study the juxtaposition of different sizes and shapes, arranged according to certain preset rules and ideas. Looking at Serial Project #1 as a whole, it appears to be nothing so much as a city, revealing LeWitt's architectural roots. It also imposes itself as a kind of framework for a finished work or series of works, imitating the preparatory sketches that precede blueprints and completed structures. Once again, LeWitt challenges the conventional methods of artistic production; in this instance, he halts the additive process of sculpting and allows the viewer to observe what would only have existed beneath other materials.
