Unfortunately, I could not access the basilica during my recent visit to the Vatican and missed seeing the sculpture in "real life."
However, as consolation, I did stumble upon Van Gogh's version of the pieta, tucked away in a small room near the exit of the Vatican Museum.
The discovery was memorable because I had been ignorant of Van Gogh's pieta before coming across it quite unexpectedly near the end of my museum visit.
