A high-resolution LiDAR survey conducted in the rugged Cuchumatanes Highlands of Guatemala has revealed a previously unknown industrial sector dedicated to the production of ceremonial mirrors. The site, sprawling over 12 hectares, features hundreds of specialized polishing platforms and clusters of dwellings for artisan families from the Late Classic Maya period.
Ground surveys following the aerial mapping identified thousands of obsidian flakes and abrasive basalt stones used for grinding the volcanic glass into reflective surfaces. This discovery suggests a highly centralized and state-controlled industry for mirrors, which were vital spiritual tools used by the Maya elite for divination and ritual communication with deities.
