***UPDATES BELOW !!!*** Part 4: "Contradictions" looks at the strange and unedifying period from 1987 to the early 21st century, when the "probably not a fake" camp appeared to have triumphed. +++I have (April 2016) one significant update to the information in this video. The initial findings of the 1995-6 radiocarbon dating of the Map parchment were presented by Garmon Harbottle at the 7th Nordic Conference on the Application of Scientific Methods in Archaeology, held in Finland, September 1996. For some reason, only his introduction, not a summary of his presentation, was given in the published proceedings of the conference, so the rest of the world had to wait quite a while for any information about the dating.+++
+++ May 2017: Another scientific update. The "mystery chemical" spotted by British Museum scientists in 1967 (see Part 3) and confirmed to be soaked into the Vinland Map parchment during radiocarbon dating in 1995 has now been identified by anaylsis of the last remaining fragment of the piece which was cut off for the dating process. It is monostearin (glycerol monostearate), a chemical which is solid at room temperature but becomes liquid at well below the boiling point of water, and has many uses in the manufacture of foods, medicines etc. (published as "Multiple Microanalyses of a Sample from the Vinland Map" in "Archaeometry" vol. 59, no. 2, pages 287-301) +++
PS: This episode is not for those of a nervous disposition. ++++ PPS: VINLAND MAP SYMPOSIUM SPECIAL MESSAGE! I've put a few thoughts inspired by the 2018 Vinland Map Symposium on my website http://www.vinlandmap.info (labelled as part seven-and-a-half of this series!).
