3. The method of subtraction of one part of the number from another. For example, 9.86, 9 – is a number of century (hundred), corresponding to 900, consequently 900-86 = 814. If we add 1 in the front we will get 1814 – the year of Paris capture.

In many prophecies, several methods are used simultaneously. For example in quatrain 9.21: if we rotate 9 in 6, swap 2 and 1 we will get 600-12 = 588, add 1 in front we will get 1588 – the year of d'Guise murder.

In any case, the digit 1 is always used as the basis for encryption. Apparently, different methods of encryption were used intentionally so that no one could decipher everything at once. The technique that I developed does not provide 100% credibility and does not always lead to decryption of the number. However, it often gives the years which correspond to the meaning of prophecies. I think Nostradamus used exactly these methods for quatrains numbers encryption and, perhaps some others.

Nostradamus prophecies come true so accurately,

that it seems that all of us – just the performers

of roles in the great Divine drama called "History”.

Quatrain 1.1 Secret cabinet

Estant assis de nuict secret estude,

Seul repose fus la selle d'airain;

Flambe exigue sortant de solitude

Feit proferer qui n'est a croire en (vain.
