Shape- the use of regular squares and rectangles overlapping one another in a conformed manner creates an image of a bustling NYC street. The bustling effect comes from the intense overlapping of the shapes- it also adds the effect that the buildings are being built/put together. The darker shapes give the piece depth and from a distance, dimension.
Cerberus was the offspring of Echidna, a hybrid half-woman and half-serpent, and Typhon, a fire-breathing giant whom even the Greek gods feared. Its brother is Orthrus, always depicted as a two-headed hellhound. The common depiction of Cerberus in Greek mythology and art is as having three heads. In most works the three-heads each respectively see and represent the past, the present, and the future, while other sources suggest the heads represent birth, youth, and old age.
