It was in the time of the Three Kingdoms that the first artists appear whose names we still know today. One of the earliest Chinese artists whose name we know is Ku K’ai-chih, who lived in the 300s AD (when Constantine was first building Constantinople in West Asia).
Ku K’ai-chih is said to have been a great portrait artist – he painted pictures of people. But nothing he painted has survived for us to look at today.
What about Sui Dynasty art?
Bibliography and further reading about Three Kingdoms Chinese art:
Art in China (Oxford History of Art Series), by Craig Clunas (1997). Not specifically , but a good introduction to the spirit of Chinese art. Warning: this one is not arranged in chronological order. Instead, it has chapters on sculpture, calligraphy, and so on.
China: Dawn Of A Golden Age (200-750 AD), by James Watt and Prudence Harper (coming soon – fall 2004). This is the catalogue from an exhibit at the Metropolitan Museum of Art in New York City – it has great pictures and also a detailed discussion of the art of this period.
