In 1917, the historian Josue Soncuya wrote about Kalantiaw in his book Historia Prehispana de Filipinas (Prehispanic History of the Philippines) where he switched the location of the story from Negros to his home province of Aklan on the island of Panay because he found two Aklanon words in the Code.
Other authors throughout the 20th century, and up to the present day, further embellished the Kalantiaw story, but in 1968 the historian William Henry Scott debunked the hoax in his book Prehispanic Source Materials for the Study of Philippine History. Kalantiaw is no longer a part of the standard history texts in the Philippines, but the story is still believed by some people, especially in the central provinces.
