The documents pinpoint two transactions that have not been reported: one in 2009 involving the use of a false name, and another in 2010 in which the Vatican Bank withdrew €650,000 from an Italian bank account but ignored bank requests to disclose where the money was headed. Yet the scandal is hardly the first for the bank, already distinguished from other banks by the fact that its cash machines are in Latin and priests use a private entrance.

In 1986, a Vatican financial adviser died after drinking cyanide-laced coffee in prison. Another, Roberto Calvi, was found dangling from a rope under London’s Blackfriars Bridge in 1982, his pockets stuffed with money and stones. The incidents blackened the bank’s reputation, raised suspicions of ties with the Mafia, and cost the Vatican hundreds of millions of dollars in legal clashes with Italian authorities.

Prosecutors alleged the Vatican ignored regulations that foreign banks must communicate to Italian financial authorities where their money has come from. All banks have declined to comment.
