One of the most interesting Attic vases in the “J.J. Winckelmann Antiquity Museum” in Trieste is the little red-figure
hydria inv. 1800, which early in the 20th century has been wrongly classified as a fourth-century production of a Campanian
workshop. It is in fact a late Classical Attic vase, close in style to the Beazley’s Bull Painter. This paper discusses the iconographic,
stylistic and archaeological issues of the vase. The proposed date in the last quarter of the 5th century BC is linked to the
chronology of three stratified deposits of the Athenian Agora (Q 15:2; B 13:5; A-B 21-22:1), in which fragments from the
Shuvalov Painter workshop have been found. All the concerned deposits contain a large amount of late Classical fine pottery
and are dated by the excavators around 425/420-400 BC.
