A remote rock-cut grotto dating to the Vishnukundina era has been discovered in the Nallamala forest of Telangana. The site contains a series of murals that utilize a zinc-based pigment, resulting in a vibrant white-and-silver color palette that has survived for over 1,300 years. The paintings depict scenes from the early Puranic texts, including the Varaha incarnation of Vishnu.
Researchers state that the use of zinc in mineral pigments at this early date is extremely rare in South Asian art. The grotto was likely a secluded retreat for ascetic monks and royal patrons. Efforts are currently underway to implement humidity controls within the cave to prevent the delicate pigments from flaking now that the chamber has been opened to the atmosphere.
