On first visiting Italy one is struck by the liberal display of a certain abbreviated inscription that, on inquiry, turns out to have been in common use in ancient times. The letters SPQR serve as a constant reminder of the antiquity and glory of Rome, but only to those schooled in Latin and ancient history. One also finds that the letters INRI adorn a number of Renaissance paintings, the meaning of which was undoubtedly better known to the medieval than to the modern (non-Italian) citizen. And how many nontheologians understand the meaning, or know that there are two possible meanings, of the letters IHS, which have for centuries appeared on church altars?
