Bilingual vase painting is a special form of ancient Greek vase painting. The term, derived from linguistics, is essentially a metaphorical one; it describes vases that are painted both in the black-figure and in the red-figure techniques. It also describes the transitional period when black-figure was being gradually replaced in dominance by red-figure, basically the last quarter of the 6th and the very beginning of the 5th century BC. Their appearance may be due to the initial uncertainty of the market for the new red-figure style, although that style subsequently became dominant rather fast.
