Curzio Inghirami was an Italian nobleman from Tuscany. He gained fame at the age of 19 for fabricating and "discovering" Etruscan artifacts, which he called "scariths" in November 1634. He dedicated much of his life to this fabrications. Despite obvious inconsistencies in the language used (many scariths used Latin vocabulary but made Tuscan references) However, his big mistake was that he had his Etruscan write on rag paper rather than on linen cloth (one even had a Tuscan watermark). Despite these many questions, Inghirami defended his works, and continued to produce them for fifteen years. There are those who argue to this day that Inghirami was not the responsible party, but that he was also a victim. 
Curzio Inghirami visited Grantville and learned of his role in the Etruscan document forgeries. He then returned to his home and began the exact same project, only using linen. However, American Lewis Bartolli was in Curzio's home county and deduced his fabrication, as Curzio had used contemporary ink, which was iron-based and acidic. Curzio admitted the forgery to his uncle after Bartolli proposed to examine the "scariths" for fingerprints, as his thumb was scarred after being cut in a boating accident, and the scar would show in his fingerprints.
However, official blame for the forgeries was placed on Michel Ducos, who had been known to use forgery as a tactic; and it was officially stated that Curzio's enthusiasm for history had "misled" him into disseminating the "scariths". Grand Duke Ferdinando II de' Medici arranged for him to enter the University of Florence, so he could fill the gaps in his education which had led him to be deceived by the forgeries.
