Ornaments alone cannot make a classical garden. But such landscapes are inherently architectural and rely on structure to help give them form. Scale and placement are key, and the character of certain pieces can set a whole mood. Ancient Romans similarly mixed it up: placing the busts of philosophers in certain areas to spark serious conversation, and those of playful demigods to set the mood for pleasure and relaxation. They even had a name for their love of outdoor living: otium.
