This photo manipulation is inspired by Dan Brown's novel "Inferno" which talks a lot about the Black Death that happened in 14th century and took the life of estimated 200 millions people.
The man in black cloak is not the angel of death or a grim reaper; it's a doctor wearing a plague mask that used a lot in those times.
