Ancient Painting was the first survey-style work to treat all of ancient art, from Paleolithic cave painting to the late antique ("early Christian art"). It became a standard for the classroom and ushered in the genre writing of that subject. As the editor of the AJA, she had major influence over the development of archaeology in the United States (Medwid).
