This type of sundial is called a hemispherium. The gnomon casts a shadow and serves as a nodus. The height of the nodus-shadow within the bowl gives the times of year. When the sun is low in the sky in the winter, the nodus-shadow will be higher in the bowl and in summer the shadow will be lower. A companion piece to the present sundial, in the Baur Collection, Geneva, is illustrated in John Ayers, Chinese Ceramics in the Baur Collection, Geneva, 1999, vol. II, no. 250.  This is a variation of the more classic sundial consisting of a stone disk and a needle placed on a stone platform at an angle. Two Ming dynasty examples can be found in the ancient observatory in Beijing and outside the Hall of Supreme Harmony inside the Forbidden City.

In its technique, the sundial shows a good understanding of contemporary lacquer wares carved with a similar decorative ground, perhaps there was an original example that served as a blueprint. Noteworthily, the same moulded diaper motif can be found on a porcelain tripod incense burner, in the collection of the National Palace Museum, Taipei, included in the museum’s Special Exhibition of K’ang-his, Yung-Cheng and Ch’ien-Lung Porcelain Ware from the Ch’ing Dynasty in the National Palace Museum, Taipei, 1986, cat. no. 113; and on a bowl, from the Qing court collection and still in Beijing, illustrated in Kangxi. Yongzheng. Qianlong. Qing Porcelain from the Palace Museum Collection, Hong Kong, 1989, pl. 101.
