1. The Roman anagram and its superstition

The number 17 exists mathematically in all cultures, but in ancient and medieval Roman Italy, the notation XVII generates a persistent ambiguity: its four letters (X, V, I, I) visually recombine into "VIXI", first person past tense of the verb "vivere" (to live), literally "I have lived". In the lingua italica, "VIXI" is the classic epitaph for Roman tombs, implicitly "I have finished living". This assimilation of 17 to epitaph is documented by Roman historians (Tacitus, Suetonius mention porters who refused seats numbered 17 at the circus games), but the historical extent of this pre-modern superstition remains uncertain.

Practical recommendations

To do

  • Accepter l'omission du 17 en Italie comme fait culturel héritée de l'épigraphie romaine. Reste sans enjeu majeur si vous demandez un siège/chambre par localisation plutôt que par numéro.

Avoid

  • Ne pas exprimer surprise ou moquerie face à l'absence du 17 sur les avions italiens. Ne pas demander un siège 17 sur Alitalia si vous travaillez avec des interlocuteurs italiens — c'est considéré comme manque de respect envers les traditions.
