The earliest surviving image of the Crucifixion appears to be an anti-Christian graffito discovered in 1857. It is carved on plaster on a wall near the Palatine Hill in Rome, now in the Palatine Antiquarium Museum.
The Greek inscription, translated as "Alexamenos worshipping his God," is scratched on the graffiti, causing it to be known as the "Alexamenos Graffito." The date of this graffito has been estimated as between 50 and 250 CE.
This architectural proof of Jesus being crucified on a cross. The Alexamenos Graffito reflects the Roman belief that the Jews worshipped a god with the head of an ass.
What was meant to mock Jesus and the word of God ended up providing validity to the truth of Jesus and the Holy Bible.
