这块圆形样本表面呈深色且质地粗糙，由利多学研究所（Institut Lidologie）进行了详尽记录，其上呈现出醒目的凸起方格网格图案。中央有一个略微凹陷的圆形区域，上面刻有清晰的铭文，表明了其特定的实用功能。周围的混凝土路面显露出岁月痕迹和轻微的碎裂，将这坚固的铁制结构环绕其中。

The dark, heavily textured surface of this circular specimen, meticulously documented by the Institut Lidologie, features a prominent grid pattern of raised squares. A central, slightly recessed circular area bears clear inscriptions indicating its specific utility function. The surrounding concrete pavement shows signs of age and minor fragmentation, framing the robust iron structure.
