"As a feature of the common man's funeral, the open casket is a relatively recent development: around 150 years. According to Mack, it serves several purposes, aside from providing what undertakers call "the memory picture." It reassures the family that, one, their loved one is unequivocally dead and not about to be buried alive, and, two, that the body in the casket is indeed their loved one, and not the stiff from the container beside his." --
