Phraya Anuman Rajadhon was the first Thai scholar to conduct a serious study of Thai folkloristics, taking notes on the nocturnal village spirits of Thai folklore. He established that since such spirits were not represented in paintings or drawings, they were purely based on popular traditional oral stories. Thus most of the contemporary iconography of ghosts such as Nang Tani, Nang Ta-khian,[2] Krasue, Krahang,[3] Phi Am, Phi Hua Kat, Phi Pop, Phi Phong, Phi Phraya, Phi Tai Hong and Mae Nak Phra Khanong[4] has its origins in Thai films that have become classics.[5]
