planetary nicks,
With their own influence will fetch 'em
Down from their orbs, arrest and catch 'em;
Make 'em depose and answer to
All questions, ere they let them go.
Bombastus kept a devil's bird
Shut in the pummel of his sword,
And taught him all the cunning pranks
Of past and future mountebanks.
_Hudibras_, part ii. canto 3.

By means of the zodiac, astrologers pretended to account for the various
disorders of the body, which were supposed to be in a good or had
disposition, according to the different aspects[68] of these signs. To
mention only one instance, they pretended that great caution ought to be
used in taking medicine under Taurus, or the bull; because, as this
animal chews his cud, the person would not be able to keep it in his
stomach.

Each hour of the day had also its presiding star. The number seven, as
being that of the planets, became of mighty consequence. The seven days
in the week,--a period of time handed down by tradition, happened to
correspond with the number of the planets: and therefore they gave the
name of a planet to each day; and from thence some days in the week were
considered more fortunate or unlucky than the rest; and hence seven
times seven, called the climacterical period of hours, days, or years,
were thought extremely dangerous, and to have a surprising effect on
private persons, the fortunes of princes, and the government of states.
Thus the mind of man became distressed by imaginary evils, and the
approach of these moments, in themselves as harmless as the rest of
their lives, has by the strength of the imagination, brought on the most
fatal effects.

Nay, the influence of the planets were extended to the bowels of the
earth, where they were supposed to produce metals. From hence it appears
that when superstition and folly are once on foot, there is no setting
hounds to their progress. Gold, as a matter of course, must be the
production of the sun, and the conformity in point of colour,
brightness, and value, was a sensible proof of it. By the same mode of
reasoning, the moon produced all the silver, to which it was related by
colour; Mars, all the iron, which ought to be the favourite metal of the
god of war. Venus presided over copper, which she might be well supposed
to produce, since it was found in abundance in the isle of Cyprus, the
supposed favourite residence of this goddess. In the same strain, the
other planets presided over the other met
