" Neckties had been required six days a week when Langdon attended Phillips Exeter Academy, and despite the headmaster’s romantic claims that the origin of the cravat went back to the silk fascalia worn by Roman orators to warm their vocal cords, Langdon knew that, etymologically, cravat actually derived from a ruthless band of “Croat” mercenaries who donned knotted neckerchiefs before they stormed into battle. To this day, this ancient battle garb was donned by modern office warriors hoping to intimidate their enemies in daily boardroom battles. "

― Dan Brown , The Lost Symbol (Robert Langdon, #3)
