Incised with artist's signature in English, numbered, credited and dated on the underside. In this autumn auction, we are honoured to present Hsiung Ping-Ming's most representative masterpiece of the Buffalo series, Kneeling Cow. This work occupies a central position in many of the artist's publications and exhibitions, and another edition of it is in the collection of the National Art Museum of China. Moreover, it is of great significance in the artist's career: in the 1960s, when the famous physicist Yang Chen-Ning visited his close friend Hsiung Ping-Ming in France, he was fascinated by the Kneeling Cow. Both of them were faithful readers of Lu Xun. Yang Chen-Ning blurted, "this shall be the 'A Willing Ox' (ruziniu)". From 2000 to 2002, Nanjing University invited Hsiung Ping-Ming to make a large-scale sculpture for the centennial celebration of the university. The artist chose this sculpture, Kneeling Cow, as a prototype for enlargement, and renamed it Ruzi Niu in homage to the spirit of Lu Xun. When he completed the sculpture, Wu Guanzhong, and Yang Chen-Ning gave it inscriptions. Today, "Ruzi Niu" still serves as an important symbol of the spirit of Nanjing University, inspiring countless students.
