What is Pan Painter?

The Pan Painter was an ancient Greek vase-painter of the Attic red-figure style, probably active c. 480 to 450 BC. John Beazley attributed over 150 vases to his hand in 1912:

Cunning composition; rapid motion; quick deft draughtsmanship; strong and peculiar stylisation; a deliberate archaism, retaining old forms, but refining, refreshing, and galvanizing them; nothing noble or majestic, but grace, humour, vivacity, originality, and dramatic force: these are the qualities which mark the Boston krater, and which characterize the anonymous artist who, for the sake of convenience, may be called the 'master of the Boston Pan-vase', or, more briefly, 'the Pan-master'.
