Funeral statuary evolved during this period from the rigid and impersonal kouros of the Archaic period to the highly personal family groups of the Classical period. These monuments are commonly found in the suburbs of Athens, which in ancient times were cemeteries on the outskirts of the city. Although some of them depict "ideal" types—the mourning mother, the dutiful son—they increasingly depicted real people, typically showing the departed taking his dignified leave from his family. This is a notable increase in the level of emotion relative to the Archaic and Geometrical eras.
