Mick asked about the weather forecast and Fred responded that in Ouray, any prognostication was speculative and definitely regional—for real accuracy, one looked out the window or guessed.
If you need a checkup now, the stars are in your favor as your physician will be accurate in his prognostication.
Both this and Pantagruel itself were published under the anagrammatic pseudonym of "Alcofribas Nasier," shortened to the first word only in the case of the Prognostication.
On the other hand, it is urged that, though Guyon and Du Verdier were in a sense contemporaries, they wrote long after the events, and that the testimony of the former is vitiated, not merely by its extreme vagueness, but by the fact .that it occurs in a plaidoyer, tending to exculpate physicians from the charge of unorthodoxy; that Du Verdier in another place assigns the Pantagrueline Prognostication to this same unknown student of Valence, and had therefore probably confused and hearsay notions on the subject; that the rasher and fiercer tone, as well as the apparent repetitions, are sufficiently accounted for on the supposition that Rabelais never finally revised the book, which indeed dates show that he could not have done, as the fourth was not finally settled till just before his death; and that it is perfectly probable, and indeed almost certain, that it was prepared from his papers by another hand, which is responsible for the anachronous allusions above referred to.
Thus if on a certain occasion the rise of the new moon in a cloudy sky was followed by victory over an enemy or by abundant rain, the sign in question was thus proved to be a favourable one and its recurrence would be regarded as a good omen, though the prognostication would not necessarily be limited to the one or the other of those occurrences, but might be extended to apply to other circumstances.
