Sundial with rosettes and lion's paws

In this hollow globe sundial, a hole at the zenith of the globe functions as gnomon (indicator). The work was abandoned and the hour lines corrected - either to a different latitued or in order to amend an error. Construction and execution of hollow globe sundials were particularly difficult.本中空球形日晷的球体天顶处设有孔洞，该孔洞充当晷针（gnomon）。该作品曾遭搁置，其时辰线亦经修正——或为适配不同纬度，或为修正误差。中空球形日晷的制作与施工难度尤高。
