Iesus Nazarenus

“At Jesus’ execution, the Roman letters INRI formed the initials of a sarcastic Latin title: Iesus Nazarenus Rex Iudaeorum, ‘Jesus of Nazareth, King of the Jews.’. . .
    Julius Caesar was actually named Iulius (Yoolius). The emperor Trajan was Traianus (Trah-yahn-us). . . . Whatever future claim the letter J might have on these words in English, they began in Latin with rather different sounds and spellings. . . .”
