Works
The Prophecies - In this book he collected his major, long-term divinations. The first installment was published in 1555. The second, with 289 further prophetic verses, was printed in 1557. The third edition, with three hundred new quatrains, was reportedly printed in 1558, but nowadays only survives as part of the omnibus edition that was published after his death in 1568. Given printing practices at the time, no two editions turned out to be identical, and it is relatively rare to find even two copies that are exactly the same.
The Almanacs - By far the most popular of his works, these were published annually from 1550 until his death. Often he published two or even three in a single year, entitled either Almanachs (detailed predictions), Prognostications or Presages (more generalized predictions). See also here.
Nostradamus was not only a diviner, but a professional healer, too. We know that he wrote at least two books on medical science. One was an alleged "translation" of Galen, and in his so-called Traité des fardemens (basically a medical cookbook containing, once again, materials borrowed mainly from others) he included a description of the methods he used to treat the plague �?none of which (not even the bloodletting) apparently worked. The same book also describes the preparation of cosmetics.
A manuscript normally known as the Orus Apollo also exists in the Lyon municipal library, where upwards of 2000 original documents relating to Nostradamus are stored under the aegis of Michel Chomarat. It is a purported translation of an ancient Greek work on Egyptian hieroglyphs based on later, Latin versions, all of them unfortunately ignorant of the true meanings of the ancient Egyptian script, which was not in fact deciphered until the advent of Champollion in the 19th century.
Since his death, only the Prophecies have continued to be popular, but in this case they have been quite extraordinarily so. Indeed, they have seldom, if ever, been out of print. This may be due partly to popular unease about the future, partly to people's desire to see their lives in some kind of over-all cosmic perspective and so to give meaning to them �?but above all, possibly, to their vagueness and lack of dating, which enables them to be wheeled out after every major dramatic event and retrospectively claimed as 'hits'.
The role of interpretation
Nostradamus enthusiasts have credited him with predicting numerous events in world history, including the French Revolution, the atom bomb, the rise of Adolf Hitler and the September 11 attacks on the World Trade Center. Indeed, they regularly make similar claims regarding each new world crisis as it comes along; there is a persistent tendency to claim that 'Nostradamus predicted whatever has just happened'.
Nostradamus does not in fact mention any of the above specifically, not even Hitler: the name Hister, as he himself explains in his Presage for 1554, is merely the classical name for the Lower Danube, while Pau, Nay, Loron �?often claimed to be an anagram of 'Napaulon Roy'�?evidently refers simply to three neighboring towns in south-western France close to the seer's one-time home territory. Such typical popular pieces of linguistic sleight of hand are particularly easy to carry out when the would-be commentator knows no French to start with, especially in its 16th-century form �?to say nothing of French geography. Not surprisingly, then, detractors see such 'edited' predictions as examples of vaticinium ex eventu, retroactive clairvoyance and selective thinking, which find non-existent patterns in ambiguous statements. Because of this, it has been claimed that Nostradamus is "100% accurate at predicting events after they happen", while the seer has acquired even more disrepute than he possibly deserves.
Skeptics of Nostradamus state that his reputation as a prophet is largely manufactured by modern-day supporters who shoehorn his words into events that have either already occurred or are so imminent as to be inevitable, a process known as "retroactive clairvoyance". A good demonstration of this flexible predicting is to take lyrics written by modern songwriters (e.g., Bob Dylan) and show that they are equally "prophetic". (For Dylan see Masters Of War , As I Went Out One Morning, Gates Of Eden, A Hard Rain's A-Gonna Fall, It's Alright, Ma (I'm Only Bleeding), etc.) It has been stated, probably correctly, that no Nostradamus quatrain has ever been interpreted as predicting a specific event before it occurred beyond a very general level (e.g., a fire will occur, a war will start).
Some scholars believe that Nostradamus wrote not to be a prophet, but to comment on events that were happening in his own time, writing in his elusive way �?using highly metaphorical and cryptic language �?in order to avoid persecution. This is similar to the Preterite interpretation of the Book of Revelation; John (the Divine) intended to write only about contemporary events, but over time his writings became seen as prophecies.
The bulk of the quatrains deal with disasters of various sorts. The disasters include plagues, earthquakes, wars, floods, invasions, murders, droughts, battles and many other related themes �?all of them foreshadowed by the Mirabilis liber. Some quatrains cover these in over-all terms; others concern a single person or small group of persons. Some cover a single town, others several towns in several countries. All of them are presented in the context of the supposedly imminent end of the world �?a conviction that sparked numerous collections of end-time prophecies at the time, not least an unpublished collection by Christopher Columbus.
