Technological and scientific studies using portable XRF on earthen rendered wall paintings were executed in the wide context in Eurasia, such as Iran, India, Eastern Turkistan-China mainly AD 1-9thcenturies. Wall paintings in the Kizil grottos of Eastern Turkistan showed similarities in the manufacturing techniques and usages of painting materials with Bamiyan oil paintings, however, they were identified as water-based paintings which could be some earlier stage of the emergence of oil based techniques. Wall paintings of Horezu monastery, Romania, of the late 17thcentury were identified as ‘secco’ paintings depicted with various arsenic based pigments and metal leaves, which could be rather related to Central Asian medieval techniques than Western European ones. In order to conclude possible origin of drying oil techniques in wall paintings, it is essential to widen research regions to northern India, Ladakh, which had early Buddhist monasteries with ‘lanterndech’ style ceilings.
