Top left corner: The oldest known depiction of the Crucifixion of Jesus seems to be some Roman graffiti from about the year 200 AD. It's called the Alexamenos Graffito and it's a mockery of Christianity - Jesus has the head of a donkey and the words say: "Alexamenos worships his God."

Bottom right corner: After WWII Salvador Dalí (1954) entered his "nuclear mysticism" phase, fascinated both by Catholicism and nuclear physics. Strange, dreamlike, ambiguous, and impossible - but all realistically portrayed.
