  2. According to Jun Cheng’s “Traditional Lion Art in China (中國傳統獅子工藝),” published by Beijing Arts and Crafts Publishing House (北京工藝美術出版社, 2013, Beijing), there are six pairs of bronze lion statues in the forbidden city, which are located in front of Taihe Gate (太和門), Qianqing Gate (乾清門), Yangxin Dian (養心殿), Changchun Palace (長春宮), Ningshou Gate (寧壽門), and Yangxing Dian (養性殿), respectively. Three male lions in front of Qianqing Gate, Ningshou Gate, and Yangxing Dian step on balls decorated with fullerene-like patterns; whereas the two balls under male lions in front of Yangxin Dian and Changchun Palace have triangular tiling patterns.

  4. The Qing Dynasty inherited the Forbidden City directly from the Ming Dynasty. Without the need to build a new palace, the focus thus moved to the construction of the Imperial Gardens. In the peak of the Qing dynasty (Qianlong’s reign), more than 90 imperial gardens were built in the great Beijing area. The most famous gardens among them are Yuanmingyuan (Old Summer Palace, 圓明園) and Qingyiyuan (清漪園). Both Yuanmingyuan and Qingyiyuan were destroyed by Anglo-French armies during the Second Opium War in 1860. Between 1884 and 1895, during the reign of the Guanxu Emperor, Qingyiyuan was reconstructed and given its present-day name, “Yiheyuan” (New Summer Palace). There were at least two pairs of bronze lion statues in the Yuanmingyuan and one pair of bronze lion statues in the Qingyiyuan. The British army took one pair of bronze lion statues located in Yuanminyuan during the Second Opium War and returned them back to China more than 100 years later, in 1984. This pair is now located in the Diaoyutai State Guest House, Beijing. The other pair from Yuanmingyuan is now located in front of Paiyun Gate of Yiheyuan.

  8. Some artefacts with a fullerene-like form, and even with that of C60, dated from Antiquity (Hellenistic/Roman times). For instance, Jos Janssen found in Kunsthistorisches Museum in Vienna a Late-Roman sprinkler from the Eastern Mediterranean area, the spherical part of which is decorated by pentagons and hexagons presumably in the form of C60 (see Ref. 9).
