SIGNED BY PAMPHAIOS AS POTTER, CIRCA 520 B.C.

The red figure technique was invented in Athens circa 530 B.C. or slightly earlier. A small number of vases produced during the last quarter of the 6th century B.C. employ both the older black figure technique together with the new red figure. For such vases Beazley coined the term "bilingual" (see p. 18 in B. Cohen, "Bilingual Vases and Vase-Painters," in Cohen, ed., The Colors of Clay, Special Techniques in Athenian Vases).

This unusually large bilingual eye-cup, not yet assigned to a specific painter, is by the same hand as on another signed by Pamphaios as potter, now in the Akademisches Kunstmuseum, Bonn (see Beazley Archive Pottery Database no. 200236).
