The study aims to identify the origin of mosaic stone tesserae mirrors discovered in El Caño, an archaeological site located in the Isthmus of Panamá within the archaeological tradition of Gran Coclé (750–1100 c.e.). The research objectives include (i) typological classification of the mirrors from El Caño by measuring the degree of similarity using the Jaccard coefficient, (ii) characterization of the materials used to make their stone bases, involving analyses such as optical microscopy, thin sections (petrography), Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD); and (iii) identification of the tools used in their manufacture, through observations of marks using optical microscope and electron microscopy (SEM and Back Scattered Electron Detector [BSE]). The results indicate that (i) the mirrors found in El Caño are typologically similar to Maya mirrors from the Late Classic and Postclassic periods, (ii) the rocks used to manufacture the mirror bases are quartzose sandstone not observed in the geological formations in the Isthmus, and (iii) the tools used for shaping were limestone abrasives, consistent with the abrasives used by the Maya for shaping the stone bases of their mirrors. Considering these results, it is inferred that the artisans who manufactured the mirrors found in El Caño were Maya.

来自巴拿马 El Caño(公元 750-1100 年)的黄铁矿镶嵌物马赛克:Coclé 和 Maya 地区之间互动的证据



该研究旨在确定在 El Caño 发现的马赛克石镶嵌镜的来源,El Caño 是位于巴拿马地峡的考古遗址,属于 Gran Coclé(公元 750-1100 年)的考古传统。研究目标包括 (i) 通过使用杰卡德系数测量相似程度对 El Caño 镜子进行类型学分类,(ii) 表征用于制作石基的材料,包括光学显微镜、薄片(岩相学)、能量色散光谱 (EDS)、X 射线衍射 (XRD) 等分析;(iii) 通过使用光学显微镜和电子显微镜(SEM 和背散射电子探测器 [BSE])观察标记来识别制造中使用的工具。结果表明,(i) 在 El Caño 发现的镜子在类型上与古典晚期和后古典时期的玛雅镜子相似,(ii) 用于制造镜子底座的岩石是石英砂岩,在地峡的地质构造中未观察到,以及 (iii) 用于成型的工具是石灰石磨料,与玛雅人用于塑造镜子的石基的磨料一致。考虑到这些结果,可以推断出在 El Caño 发现的镜子的工匠是玛雅人。
