From the Wikipedia page on Pope Innocent VIII 
Pope Innocent VIII (Latin: Innocentius VIII; 1432 – 25 July 1492), born Giovanni Battista Cybo (or Cibo), was Pope from 29 August 1484 to his death in 1492.
Mystery over his tombEdit
A mysterious inscription on his tomb in Saint Peter in Rome states: “Nel tempo del suo Pontificato, la gloria della scoperta di un nuovo mondo” (transl. "During his Pontificate, the glory of the discovery of a new world."). The fact is that he died seven days before the departure of Christopher Columbus for his supposedly first voyage over the Atlantic, raising speculations that Columbus actually traveled before the known date and re-discovered the Americas for the Europeans before the supposed date of October 12, 1492. The Italian historian Ruggero Marino, in his book "Cristoforo Colombo e il Papa tradito" (transl. "Christopher Columbus and the betrayed Pope") is convinced of this after having studied Columbus's papers for over 25 years.
