Those who read my novel
Powdered Gold will recall the controversy over the Tucson lead artifacts discovered in the 1920s. Scott Wolter and other geologists have examined them and concluded that, based on the geology, the artifacts are at least many hundreds of years old, validating their 8th Century AD dating. But some Latin scholars have analyzed the inscriptions and concluded they were lifted from modern Latin textbooks by a hoaxer. Recently an expert on medieval Latin studied the artifacts and has declared them to be genuine:

In my mind, this pretty much resolves this issue, making these artifacts some of the most important pieces of evidence of early exploration of America.
