Massimiliano Natalucci's family told Italian newspaper Corriere Adriatico that the 45-year-old had escaped with only scratches on one leg in the Bataclan attack, which left 89 people dead.
A friend who attended the concert by the California rock band Eagles of Death Metal with him was not so lucky, and had to undergo an operation on Saturday after being hit in the shoulder.
"The terrorists were just three metres from them the whole time," Natalucci's father told the paper.
Almost exactly 30 years ago, on May 29, 1985, Natalucci, aged 15, was with his father and uncle at the Heysel stadium in Brussels for the European Cup final when a wall collapsed, killing 39 people.
Then, as on Friday, Natalucci was unhurt.
His sister Federica has a theory about her brother's luck: A kiss from Pope Jean Paul II in Rome when he was eight has protected Natalucci during both disasters.
