It depends on who does the interpretation. All of Nostadamus's quatrains were written so enigmatically that interpretation is usually garbage and many writers come up with entirely different results.

He mentioned in his preface that there were clues to the solutions in the inheritance to be given his son, Cesar. Edgar Leoni, in his own analysis, could find nothing in that inheritance that seemed to solve the quatrains, but I think he overlooked the letter to his son which was preface to the second set. The letter, itself, could have been the inheritance -- and it is full of potential clues.
