These reflections were suggested to Tacitus by the conduct of Thrasyllus (chief astrologer of the Emperor Tiberius), when his skill was tested by his imperial employer after a manner characteristic of that agreeable monarch. The story runs thus (I follow Whewell's version): 'Those who were brought to Tiberius on any important matter, were admitted to an interview in an apartment situated on a lofty cliff in the island of Capreæ. They reached this place by a narrow path, accompanied by a single freedman of great bodily strength; and on their return, if the emperor had conceived any doubts of their trustworthiness, a single blow buried the secret and its victim in the ocean below. After Thrasyllus had, in this retreat, stated the results of his art as they concerned the emperor, Tiberius asked him whether he had calculated how long he himself had to live. The astrologer examined the aspect of the stars, and while he did this showed hesitation, alarm, increasing terror, and at last declared that "The present hour was for him critical, perhaps fatal." Tiberius embraced him, and told him "he was right in supposing he had been in danger, but that he should escape it," and made him henceforward his confidential counsellor.' It is evident, assuming the story to be true (as seems sufficiently probable), that the emperor was no match for the charlatan in craft. It was a natural thought on the former's part to test the skill of his astrologer by laying for him a trap such as the story indicates—a thought so natural, indeed, that it probably occurred to Thrasyllus himself long before Tiberius put the plan into practice. Even if Thrasyllus had not been already on the watch for such a trick, he would have been but a poor trickster himself if he had not detected it the moment it was attempted, or failed to see the sole safe course which was left open to him. Probably, with a man of the temper of Tiberius, such a counter-trick as Galeotti's in

The belief in the influence of the stars and the planets on the fortunes of the new-born child was still rife when Shakespeare made Glendower boast:
At my nativity
The front of heaven was full of fiery shapes
Of burning cressets; know, that at my birth
The frame and huge foundation of the earth
Shook like a coward.
And Shakespeare showed himself dangerously tainted with freethought in assigning (even to the fiery Hotspur) the reply:
So it would have done
At the same season, if your mother's cat
Had kittened, though yourself had ne'er been born.
In a similar vein Butler, in
As if the planet's first aspect
The tender infant did infect
In soul and body, and instil
All future good and future ill;
Which in their dark fatalities lurking,
At destined periods fall a-working,
And break out, like the hidden seeds
Of long diseases, into deeds,
In friendships, enmities, and strife.
And all th' emergencies of life.

It is commonly stated that Bacon opposed the Copernican theory because he disliked Gilbert, who had advocated it. 'Bacon,' says one of his editors, 'was too jealous of Gilbert to entertain one moment any doctrine that he advanced.' But, apart from the incredible littleness of mind which this explanation imputes to Bacon, it would also have been an incredible piece of folly on Bacon's part to advocate an inferior theory while a rival was left to support a better theory. Bacon saw clearly enough that men were on their way to the discovery of the true theory, and, so far as in him lay, he indicated how they should proceed in order most readily to reach the truth. It must, then, have been from conviction, not out of mere contradiction, that Bacon declared himself in favour of the Ptolemaic system. In fact, he speaks of the diurnal motion of the earth as 'an opinion which we can demonstrate to be most false;' doubtless having in his thoughts some such arguments as misled Tycho Brahe.

To Bacon's theological contemporaries this must have seemed a dreadful heresy, and possibly in our own days the assertion would be judged scarcely less harshly, seeing that the observance of the (so-called) Sabbath depends directly upon the belief in quite another origin of the week. Yet there can be little question that the week really had its origin in astrological formulæ.

The astrologers were exceedingly ingenious in showing that their art had given warning of the great plague and fire of London. Thus, the star which marks the Bull's northern horn—and which is described by Ptolemy as like Mars—was, they say, exactly in that part of the sign Gemini which is the ascendant of London, in 1666. Lilly, however, for whom they claim the credit of predicting the year of this calamity, laid no claim himself to that achievement; nay, specially denied that he knew when the fire was to happen. The story is rather curious. In 1651 Lilly had published his

Sir Toby Belch and Sir Andrew Aguecheek were evidently not well taught in astrology. 'Shall we set about some revels?' says the latter. 'What shall we do else?' says Toby; 'were we not born under Taurus?' 'Taurus, that's sides and heart,' says sapient Andrew. 'No, sir,' responds Toby, 'it's legs and thighs. Let me see thee
