An identical tile is illustrated by Thornton and Wilson, Italian Renaissance Ceramics, catalogue of the British Museum Collection, no. 376 (vol. II). Other examples include a set of 34 in the Museo dell'Opera del Duomo, Siena and 115 in the Museo Internazionale delle Ceramiche, Faenza. The pavement was replaced in 1839 with tiles made at Doccia. This is presumably when these tiles began to appear on the market; one tile at the Sèvres museum was presented in 1847.
