Quotes

I had determined to go as far as declaring in abstruse and puzzling utterances the future causes of the "common advent", even those truly cogent ones that I have foreseen. Yet lest whatever human changes may be to come should scandalise delicate ears, the whole thing is written in nebulous form, rather than as a clear prophecy of any kind.
- Letter from Salon to his son Cesar (March 1555) as translated by Peter Lemesurier

Tomorrow, I shall no longer be here.
- Last words, as quoted in Famous Last Words: The Ultimate Collection of Finales and Farewells‎ (2004) by Laura Ward and Robert Allen; reported to have been said to his secretary Jean de Chavigny

Les Propheties (1555)

The Prophecies, often referred to as the Centuries there are numerous translations and interpretations of these verses.

Preface

If I have eschewed the word prophet, I do not wish to attribute to myself such lofty title at the present time, for whoever is called a prophet now was once called a seer; since a prophet, my son, is properly speaking one who sees distant things through a natural knowledge of all creatures. And it can happen that the prophet bringing about the perfect light of prophecy may make manifest things both human and divine, because this cannot be done otherwise, given that the effects of predicting the future extend far off into time.

Perfect knowledge of such things cannot be acquired without divine inspiration, given that all prophetic inspiration derives its initial origin from God Almighty, then from chance and nature. Since all these portents are produced impartially, prophecy comes to pass partly as predicted. For understanding created by the intellect cannot be acquired by means of the occult, only by the aid of the zodiac, bringing forth that small flame by whose light part of the future may be discerned. We need god to prosper those without him will not.

Estant assis de nuit secret estude,
Seul repousé sur la selle d'ærain,
Flambe exigue sortant de solitude,
Fait prosperer qui n'est à croire vain.
- Sitting alone at night in secret study;
  it is placed on the brass tripod.
  A slight flame comes out of the emptiness and
  makes successful that which should not be believed in vain.
  - Quatrain 1

When twenty years of the Moon's reign have passed
another will take up his reign for seven thousand years.
When the exhausted Sun takes up his cycle
then my prophecy and threats will be accomplished.
- Q 48

Quotes about

Were we to record the failures and ridiculous blunders of astronomers, we are afraid they would outnumber by far those of the astrologers. Present events fully vindicate Nostradamus, who has been so much ridiculed by our skeptics.
