How did John Beazley identify individual painters of ancient Greek vases?

In the field of classical scholarship, Sir John Beazley revolutionized the study of ancient Greek pottery by applying the "Morellian method"—a technique of connoisseurship originally developed for Renaissance painting—to anonymous vase painters.

Because most ancient vases are unsigned, Beazley identified individual artists by meticulously analyzing recurring stylistic "mannerisms" in the rendering of anatomical details, such as the shape of ears, eyes, fingers, and the folds of drapery. By isolating these idiosyncratic habits, he was able to group thousands of unsigned works into distinct artistic personalities.

When a painter’s real name remained unknown, Beazley assigned them descriptive names based on their subjects, the location of their primary works, or the potters with whom they collaborated, such as the "Amasis Painter." This systematic approach allowed scholars to reconstruct the careers and workshops of individual masters, transforming our understanding of the Attic black-figure and red-figure traditions.1
