Read this: High neoclassicism was an international movement. Though neoclassical architecture employed the same classical vocabulary as Late Baroque architecture, it tended to emphasize its planar qualities, rather than sculptural volumes. Projections and recessions and their effects of light and shade were more flat; sculptural bas-reliefs were flatter and tended to be enframed in friezes, tablets or panels. Its clearly articulated individual features were isolated rather than interpenetrating, autonomous and complete in themselves.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What qualities were more emphasized in neoclassical versus Baroque?
planar qualities, rather than sculptural volumes
