Why did the huge size of A Burial at Ornans surprise Salon audiences?

The massive scale of Gustave Courbet’s A Burial at Ornans (1849–50) surprised Salon audiences because it defied established artistic hierarchies regarding subject matter and size.1

In 19th-century academic tradition, monumental canvases were strictly reserved for "important" subjects, such as historical, religious, or allegorical scenes. By choosing to depict a contemporary, mundane funeral of an unnamed person on such a massive scale, Courbet challenged these conventions.1

Attendees expected scenes from everyday life—known as genre paintings—to be executed as small-scale works, similar to those of 17th-century Dutch and Flemish masters. Furthermore, the audience was accustomed to idealized, glorified depictions of death. Courbet’s stark, objective portrayal of a lackluster rural event, devoid of religious transcendence or heroism, was perceived as both incongruous and crude. This deliberate choice to elevate an ordinary, contemporary subject to the scale of history painting was a foundational act of Realism, intended to ennoble the lives of his contemporaries.1
