Note: This century is the shortest of the "legitimate" centuries of Nostradamus. After the first 41 quatrains, there is one more that came out before the Sève edition, then six that Sève introduced, likely through Coligny.
I say Sève introduced, though it is highly likely that these quatrains that were listed by Sève were actually presented by Chavigny not long after Nostradamus died.
The first 41 quatrains of this century were first seen in the Du Rosne edition of 1557
With one exception, the rest were first seen in the Sève edition of 1605.
