Acronym of Iesus Nazarenus Rex Iudaeorum. The Romans in classical times had two types of public death sentence: the crucifixion and beheading. They reserved the beheading for Roman citizens. Everyone else without the title of citizenship, were slaves or not, they were crucified and used to put in the cross, in a visible site, the reason for the punishment. In the case of Christ which crucified officially by blasphemous, although the real motives were others, also put the reason: have been declared King of the Jews: Iesus Nazarenus Rex Iudaeorum. The Pharisees protested to Pilate: do not put that, but that he was declared King of the Jews, to which Pilate replied: quod scripsi, scripsi: what I have written, written is (! Jn 19 21 ).
