Corrected entry: When Langdon, Vittoria, Ollivetti and a Swiss guard driver are in the car, the driver says "My wife and I -" before being cut off by Ollivetti, but in an earlier chapter the book states that Swiss Guard must be unmarried.
Corrected entry: Robert Langdon tells Vittoria Vetra that the Panthéon was given its name because the Romans were pantheists. Nonsense. The Romans were polytheistic.
Corrected entry: According to the book the pope has to be elected from the College of Cardinals. In reality there is no such requirement.
Corrected entry: The black camerawoman defines herself as African American. Why would a British person define themselves as American?
Corrected entry: The Forum Romanum is described as having columns looking like "toppled gravestones". The columns of the Forum are standing, not toppled.
Corrected entry: Near the beginning of the book, the X-33 airplane travels at Mach 15, "hurtling through space at 11,000 miles per hour." There's a slight problem with this, however: 11,000 miles per hour at this altitude (60,000 feet) is actually over Mach 16, because the speed of sound decreases with altitude.
