Jesus Nazarenus Rex Judaeorum - Jesus of Nazareth, King of the Jews.
Igne Natura Rerun vatur Integra - By fire, nature is perfectly renewed.
The initials of the Latin sentence which was placed upon the cross: Jesus Nazarenus Rex Judaeorum, meaning Jesus of Nazareth, King of the Jews. The Rosicrucians used them as the initials of one of their Hermetic secrets: 'Igne Natura Rerun vatur Integra,' meaning that By fire, nature is perfectly renewed. They also adopted them to express the names of their three elementary principles salt, sulphur, and mercury by making them the initials of the sentence, Igne Nitrum Roris Invenitur. This corresponds with the Hebrew equivalent letters and initials of the ancient elements: Iaminim, water; Nour, fire; Ruach, air; and Iebschah, earth."
