Portraits made during the lifetime of a person were exceedingly rare at this time, and most "portraits" were actually produced by the imagination of the artist rather than being a true likeness of the individual. The same woodblock was often used to print the portrait of different personalities. An example is the first known printed image of spectacles, found in the Rudimentum Novitiorum by Lucas Brandis, printed in Lübeck, Germany, in 1475.4 The person depicted was variously identified as Philo, Empedocles, Seneca, or Pythagoras (Catherine Hitchens, BA, e-mail communication, December 18, 2000) (Figure 1).
