Great questions. I would probably like to go back to more than one time in history, but this two for sure:
- The surrender of Granada, the entrance of Isabel de Castilla in la Alhambra.
- The last supper of Jesus with the Apostles.
Why ? Because of the importance of these two episodes in the history of the western civilization.
I wouldn't change anything, just enjoying being witness of those moments in history.
Definitely I would have liked to meet the Queen Isabel de Castilla and also Jesus and the Apostles.
The last question is the most difficult to answer, and imagine. But absolutely all about their lives and check if the history facts that we know about them were true and accurate.
