In 1986, she held the post professor emerita at the Claremont Colleges and told a
Los Angeles Times reporter that she had discovered a void in Arthurian scholarship: “All the books on Arthur have been on the mythology, the legend,” but not the history. (Of course, this was not true; many books had already investigated the “
historical Arthur”.) Goodrich traveled extensively in Britain and France and laid claim to having mastered several ancient and modern languages. She claimed that the 12th century pseudo-historian,
Geoffrey of Monmouth thought that Arthur had been in Scotland, not England, hiding this by naming Arthur's battles in Latin rather than Scots
Gaelic. “When I finally figured out what he was doing, I translated the Latin back into Gaelic,” Goodrich told the
Riverside Press-Enterprise in 1994. She then found that the names coincided with places in Scotland. (The conventional view has always been that Geoffrey was describing places in southwestern England or Wales.) She claimed that Guinevere was a Pictish queen and Lancelot a Scottish king.
