James Weinberg has fully embraced the challenge of deconstructing Goya.

Somerville graphic artist James Weinberg spent nearly 20 hours examining The Parasol, a painting by the Spanish artist Francisco Goya. After a while, the details of the image started blurring together. “The dog’s paw started looking like the face,” laughs Weinberg. His task was to convert an elaborate masterpiece into a paint-by-numbers mural to be installed in Copley Square on October 18 and 19. With the help of a stepladder and an array of paints, the public will be invited to join collectively in coloring the mural over the weekend.
