Heptadecaphobia (Greek: δεκαεπτά dekaepta, "seventeen" and φόβος, phobos, "fear") or heptadekaphobia is the fear of the number 17. It is considered to be ill-fated in Italy and other countries of Greek and Latin origins, while the date Friday the 17th is considered especially unfortunate in Italy. The number is feared due to superstition, and is similar in nature to the fear of the number 13 in Anglo-Saxon countries.
It has been suggested that the Romans found the number 17 disturbing because in Roman numerals XVII is an anagram of vixi, meaning 'I have lived' (i.e. I am dead).
Friday the 17th
In mass media, the theme is portrayed in movies, such as The Virtuous Bigamist (Italian: "Era di venerdì 17") and Shriek If You Know What I Did Last Friday the 13th (Italian: "Shriek - Hai impegni per venerdì 17? ", where in English, the title refers to the number 13.)
