Three Tang dynasty bottles of this form in the Royal Ontario Museum, one a sancai-glazed example similar to the present bottle, one a bronze example and one in clear-glazed stoneware, illustrate the popularity of this form during the Tang dynasty. See Royal Ontario Museum: The T.T. Tsui Galleries of Chinese Art, 1996, pl. 67. A very similar bottle from the Alan and Simone Hartman Collection was sold in these rooms, 20 March 2001, lot 119.
