Stand close to the western pediment of the Maison Carrée and you can still see the small pin-holes in the stone above the entrance. The temple's dedicatory inscription was originally spelled out in bronze letters, each fixed to the marble with two or three pins. The letters were stripped for their metal value centuries ago, but the holes remained.
The antiquarian Jean-François Séguier worked out the text in 1758 by mapping the holes to plausible letter shapes — a delicate piece of reverse-engineering that recovered a dedication to Augustus's grandsons Gaius and Lucius Caesar. A modern reconstruction now hangs in the entrance hall.
