Michael Erard's review mentions Giuseppe Mezzofanti, "the nineteenth-century Bolognese cardinal who was reputed to speak between thirty and seventy languages, ranging from Chaldaean to Algonquin" — Babel No More: The Search for the World's Most Extraordinary Language Learners. More:
- He spoke them so well, and with such a feather-light foreign accent, according to his Irish biographer, that English visitors mistook him for their countryman Cardinal Charles Acton. (They also said he spoke as if reading from The Spectator.) His ability to learn a language in a matter of days or hours was so devilishly impressive that one suspects Mezzofanti pursued the cardinalate in part to shelter himself from accusations that he had bought the talent from Satan himself.
- Among the more impressive workhorses is Alexander Arguelles, who, at the time of his first meeting with Erard, is an unemployed academic and jogging enthusiast living in California. Arguelles reads novels in Dutch, writes and reads classical Arabic, and translates Korean for cash on the side. But he also spends twelve hours every day learning languages and obsessively cataloguing his progress. In his case, the hyperpolyglottism appears to be simply compulsive behavior.
