The four letters appearing over the head of the crucified Christ. The exoteric or common explanation of these letters is derived from: "Iesvs Nazarenvs Rex Ivdaeorvm" which is "Jesus of Nazareth, King of the Jews." But there are esoteric meanings:
- Ignis Natura Renovatur Integram – Fire Unceasingly Renews Nature.
- In Necis Renascor Integer – In Death I Am Reborn Intact and Pure.
