Phaistos Disc
The possibility that the disc is a 1908 forgery or hoax has been raised by two scholars. According to a report in "The Times", the date of manufacture has never been established by thermoluminescence dating. In his 2008 review, Robinson does not endorse the forgery arguments, but argues that "a thermoluminescence test for the Phaistos Disc is imperative. It will either confirm that new finds are worth hunting for, or it will stop scholars from wasting their effort."
