 A short time before he died he finished his last book, called "Armenian Mythomania".Dagmar Lorenz, professor of Germanic Studies at the University of Illinois at Chicago, in a book review of author Edgar Hilsenrath for the Simon Wiesenthal Center Annual, notes Feigl as a supporter of "Turkish cryptofascist anti-Armenian propaganda" and condemns "A Myth of Terror" as a "revisionist publication" that "abounds with misleading details".Feigl's work was also criticized by prof. Klas-Göran Karlsson for misinterpretations.
