In the Western world, along with the Greek civilization's decline

The first part of introductory remarks 4th astronomy and the astrology separate from each other

    “pure”, take explores the natural mystery as the objective, or in the modern significance's astronomy, originally is also has existed since ancient times - - the ancient Greece astronomy is a such illustration. However since the astrology from Cuban Billen after all around proliferates, even if in the ancient Greece, “pure” the astronomy has existed, also cannot think that the astronomy and the astrology are mutually independent. The reason is obvious: Is engaged in these two kind of activities is with some people. Even if famous like hopes Palestinian exactly Si (Hipparchus, translated Hipparchus and the request forces dense (Ptolemy)-- this two people in the modern people mind is the ancient times great astronomer old), also simultaneously was astrology master. They are engaged in astronomy research this point without doubt, is also the great astronomer truly, but on the other hand, hopes Palestinian Si is his time astrology authority exactly, his horoscope theory is being cited frequently by later generation's Roman writers; The request forces densely has the well-known astrology work "Four Books" (Tetrabiblos). In fact, has arrived at the middle ages later period, the request forces the dense name first with "Four Books" relates in together. Moreover we should not forget that take hopes Palestinian Si Hetuo to force exactly as representative, is for the purpose of exploring the natural mystery densely the ancient Greece astronomy, in ancient world's other places was extremely rare, even was unique possibly.   

    In the Western world, along with the Greek civilization's decline, spirit of science's glory also belongs to dimly. Is is initially intrepid, subsequently the decayed Roman Empire. The roman gives the biggest care to legal and engineering technology and so on business, but has leisure the science to the ancient Greece which the philosophers emphasize (is to a great extent in modern significance!)It is not interested. Downward is the long middle ages again, according to certain Western writer's exaggerating view, the astronomy except for the church calculated that a religious festival, is nothing to speak of simply; But astrology, because the church is quite warm to its manner dark, also cannot talk about is very prosperous. But actually afterward emerged the Arab the big collar is coquettish in these two knowledge. Certainly the Arabic scholars also look like them the senior equally are body two - - already are engaged in the astronomy also to be engaged in the astrology, but the former is only the latter's tool to a great extent.
