“Great temples were not the work of one architect,” Gaudí observed, but as the CCNY exhibition and catalog indicate, those in charge at the Sagrada Família today have drawn on his work to the exclusion of all other possibilities. To be sure, a highly skilled, deeply dedicated group of architectural, engineering, and decorative arts professionals has been directed since 2012 by the Barcelona architect Jordi Faulí (who spent the preceding two decades as an associate on the project). The team is hewing as faithfully as possible to the letter of Gaudí’s vision, but one wonders about the spirit.
