Analysis of information sources in references of the Wikipedia article "Titov slavolok, Rim" in Slovenian language version.
According to an ancient ban placed on the monument by Rome's Jewish authorities, once a Jewish person walks under the arch, he or she can no longer be considered a Jew... the chief rabbi of Rome had told the Israeli Embassy that the original ban was no longer valid, since an independent State of Israel had been established. Unfortunately, no one who knew about the ban had ever been informed of its abrogation!
