Jordan Lead Codices

The Jordan Lead Codices, (sometimes called simply the Jordanian Codices), are a collection of codices said to have been found in a cave in Jordan and first publicized in March 2011. Several scholars have pronounced them fakes. In November 2012, A regional BBC News investigation also pronounced the codices to be fake. In December 2016, a radioactivity test performed at the University of Surrey's Ion Beam Centre confirmed the old age of the lead used, but not the inscriptions. As of 2017, both the Israeli Antiquities Authority (IAA) and the Jordanian archaeological department regard them as forgeries.
