Since the very early literary references, the shell of the tortoise was considered evocative of the cosmos, with the upper surface reminiscent of the vaulted heaven, and the underside analogous to the flat disc of the earth. As animals living a long life, tortoises symbolised longevity but also immutability and steadfastness. The use of the tortoise as support, such as in the present example, probably derives from the observation of the animal's habit of burying itself under the ground and re-emerge at certain times. The use of the tortoise as an ink-stone probably derived from the tortoise's further association with water. For reference see C.Michaelson, Gilded Dragons.
