To the scientist it proves nothing; to the believer in astrology, everything.

The significant thing is that it appeared shortly AFTER the death of the monarch.
On the Continent astrologers were even more in favor than in England.
Charlemagne, and some of his immediate successors, to be sure, attempted to exterminate them, but such rulers as Louis XI.

and Catherine de' Medici patronized and encouraged them, and it was many years after the time of Copernicus before their influence was entirely stamped out even in official life.

There can be no question that what gave the color of truth to many of the predictions was the fact that so many of the prophecies of sudden deaths and great conflagrations were known to have come true--in many instances were made to come true by the astrologer himself.

And so it happened that when the prediction of a great conflagration at a certain time culminated in such a conflagration, many times a second but less-important burning took place, in which the ambitious astrologer, or his followers, took a central part about a stake, being convicted of incendiarism, which they had committed in order that their prophecies might be fulfilled.
But, on the other hand, these predictions were sometimes turned to account by interested friends to warn certain persons of approaching dangers.
For example, a certain astrologer foretold the death of Prince Alexander de' Medici.
