CHAPTER III

PRE-BABYLONIAN SCIENCE

The transcending wonders of the phenomena of the heavenly bodies

attracted the attention of primitive man at an early period of his

intellectual development. The succession of day and night, the phases

of the moon, comets, meteorites, the eclipses of sun and moon, the

recurrence of the seasons were observed and recorded. In this way,

through long uncivilized times, many scientific facts were noticed and

handed down by tradition, and probably were among the first scientific

data collected. We have no means of determining when the primitive

science of astronomy became systematized, although there are reasons

for believing that it was roughly outlined at a remote date.

There was a tradition among the Babylonian priests that their

astronomical observations and records went back to a period of more

than 400,000 years. This statement was believed by the people of

antiquity, and was made to Alexander the Great during his Indian

campaign.

Astronomy appears to have been developed into an organized system by

the primitive peoples of central Asia. It was carried to China, India,

and Arabia by learned travelers. There were government astronomers in

China before the year 3000 B. C., and history records that two of these

officials, named Ho and Hi, were beheaded in the year 2159 B. C. for

being careless in their work and failing to issue a timely prediction

of a solar eclipse.

Chinese history also relates that the Emperor, in 2857 B. C., issued

an edict recommending the study of astronomy. From these and other

historical references we learn that nearly 5,000 years ago astronomical

science was not only well developed, but that its educational value was

recognized.

While attention was being given to the study of astronomy in China,

this science was independently developed in India. The astronomers

of India invented a different system from that of the Chinese, and

compiled numerous astronomical tables which were published and widely

used as far back as 3102 B. C.

These early astronomical studies resulted in the division of time

practically as we know it to-day. The Babylonians had a week of seven

days. The days bore names of the planets and were divided into hours

and minutes. Days were combined into months and years. The Babylonian

and Chaldean astronomers, like those of China and India, were important

men and were credited with great learning.

The Babylonian month began on the evening when a new moon was first

observed. An adjustment was made necessary between the months, owing

to the fact that the actual lunar interval is about twenty-nine and

a fraction days. Numerous astrological observations were made with

the view of obtaining data to facilitate the monthly adjustments. The

taking of these observations was made easier by maps of the heavens

which were recorded on baked clay tablets and prisms. Similar maps of

the world, with positions fixed by astronomical observations, were

likewise made in Babylonian times.

The usefulness of astronomical observations and predictions led to the

belief that they could be employed with advantage for wider purposes.

The astrologers endeavored to deduce omens and forecast horoscopes.

In order to facilitate their calculations, the astrologers invented

calculating and time-dividing machines. Tablets from the royal library

at Nineveh indicate that Chaldean astrologers possessed mechanisms

which divided the hours of the day by mechanical means. These were

forerunners of modern clocks and timepieces.

These early scientists represented the earth as a vast circular plain,

intersected by high mountain ranges and surrounded by a large river,

with other mountain chains which lost themselves in an infinite ocean.

The heavenly vault was believed to be supported by the highest peaks

of the outlying mountains. It was owing to the peculiar nature of this

cosmogony that the pre-Babylonians and Babylonians were unable to

develop a satisfactory mechanical view of the world. The world had to

wait for an adequate mechanical theory before general knowledge could

be advanced, so that men like Newton and Laplace could correct the

errors of early theories and furnish a sound working hypothesis.

The advancement of science requires methodical observations and the

use of the highest powers of the imagination. It is thinking in

picture-like figures that supplies primitive reasoning. While pure

reasoning deals with abstract, verbal images, the more concrete

picture-thinking deals with object-images. The differences between

thinkers and dreamers is chiefly in the way their minds act. But even

thinkers are supplied with thought material by the elementary mental

operation of picture-thought, dreams, or dream-thinking. Science needs

the active use of the imagination to anticipate experience and suggest

the issues of a process in course of action. Most great inventions,

and probably all primitive inventions, were stimulated by imagination.

But the imagination, unless skillfully directed, is liable to numerous

errors. That is why in all ages there has been much error in connection

with knowledge. There could, however, be little or no progress without

imaginative work. It is only within very recent years that the modern

sciences have been stripped of much absurd matter derived from crude

imaginative work. When we bear this in mind, we have the key to the

part played by ancient myths, magic, and ceremonies in developing

civilization.

The term magic is derived from the Persian term for priest. The magi,

or priests of Zoroaster, their religion, learning, and occult practices

had important world-wide effects just before the Babylonian era. Magic

is a pioneer of religion, philosophy, and science.

Medicine was benefited, in some ways, by the priests seeking means for

dealing with the work of the spirits of evil. Chemistry and metallurgy

were also advanced, and new realms of knowledge were opened even by

magicians.

The magic of the Babylonians survived their empire. It was handed over

to the Egyptians and contemporary peoples, and was in turn passed

down to the magicians and alchemists of the Middle Ages, and to the

dramatists, poets, and novelists of all ages.

The accumulation of scientific facts was greatly facilitated by the

improvements made by the Babylonians in the manufacture of earthenware

tablets, scrolls, and prisms. Beautifully drawn cuneiform picture signs

recorded on these all the knowledge of the day. These stonelike records

were filed away in many monasteries and libraries. Subsequently,

letters were invented, alphabets were formed, and writing displaced the

hieroglyphic symbols.

The invention of alphabets made reading easier. This resulted in giving

an impetus to education which has had cumulative effects right down

through the ages.

We are now in a position to realize why scientific discoveries were

made very slowly, and at long intervals apart, in early times. Facts

had to be accumulated, studied, grouped, and compared. Accounts of

these studies had to be pictured and stored away for future use. Only

exceptionally learned men did this. But when alphabets were invented

and education increased, numerous minds became active and there was

a great extension of thought, experimentation, and philosophical

contemplation. This was followed by the establishment of new religious

houses, schools, and philosophical academies, at all of which the

ablest men of the day emulated the scholars in formulating theories and

making inventions.

Soon after the perfecting of cuneiform writing in Babylon, characters

were devised for representing numbers. A vertical, arrowlike wedge

represented the figure 1, while a horizontal wedge stood for 10.

A vertical and horizontal wedge, placed together, signified 100.

Other arrangements of these characters meant that they were to be

multiplied, subtracted, divided, or added together. In this simple

manner all kinds of arithmetical results could be recorded.

The Babylonian mathematicians were familiar with decimals, integers,

and fractions, and their tables and records of astronomical and

engineering calculations reveal a remarkably high degree of

mathematical ability, indicating that peoples who preceded us by

several thousands of years were familiar with the more important

calculations requisite in trade and industry as well as for

astrological computations.

Babylon was a great world metropolis. It occupied a position similar

to that occupied by London to-day. Its merchants were engaged in

world-wide commercial operations which needed good systems of

bookkeeping and accountancy. These, in turn, presupposed a highly

developed arithmetical system. Practically all the arithmetical

calculations used in commerce to-day were employed by them. Their

accountants, like those of China to-day, used the abacus, or

calculating machine.

A lucid illustration of the accuracy of ancient calculations, the

efficiency of their reports, and the confidence with which they

executed intellectual duties is afforded by the following translation

of a Babylonian astronomer's official report:

"To the King, my lord, thy faithful servant, Mar-Istar.

"... On the first day, as the new moon's day of the month of

Thammuz declined, the moon again became visible over the planet

Mercury, as I previously had predicted that it would to my master

the King. My calculations were accurate."

The records of Babylon furnish us with a wealth of documents of this

character.

The numerous peoples of India have always been divided into castes.

This has resulted in the pioneering work in science falling to

the priests. However, the principal priests were among the most

intellectual men of each generation and, as they traveled in search

of instruction, India was always in contact with the progress made in

China, central Asia, and Babylonia. These great centers of ancient

learning progressed together.

The Indians were able mathematicians and discovered and developed at an

early period what is now known as "Arabic notation." In this work they

were assisted by the Babylonians.

The Indians, like the Chinese and Babylonians, solved problems in

interest, discounts, partnership, the summation of arithmetical and

geometrical series, and determined number changes in combinations and

permutations with ease. They were also proficient in algebra, the

extraction of the roots of numbers, various classes of equations, and

the principles of trigonometry.

The Chinese have always been good mathematicians. It is probably due

to this fact that they have at all times been such able traders and

bankers.

We are not so familiar with the works of Chinese mathematicians in

pre-Babylonian times as we are with the Indian; but the references of

contemporary writers indicate that the Chinese scientists were as able

and active as their contemporaries.

We have remarked the high degree of perfection which was attained in

the Babylonian era by scholars in science and mathematics. Similar

perfection was attained in art, industry, law, and medicine. The

wonderful law work that has come down to us under the name of the code

of Hammurabi indicates not only the extensive progress which had been

made in law, but incidentally through its references the progress of

agriculture, industry, commerce, and business.

Many references in the Hammurabic code, written about 2300 B. C.,

show that the medical profession had attained considerable advance

in Babylon. Surgeons were daring operators. They commonly performed

operations for cataract. Many of the common major operations now

performed by surgeons were also done by the ancients. They were experts

at setting fractured bones. The physicians made effective use of drugs.

Many drugs employed to-day were known to them.

The discoveries of the early oriental nations were collected and

developed in Babylon. The entire fields of science, mathematics,

geometry, agriculture, astronomy, philosophy, and art were focused in

Babylon and handed down to the Egyptians and the Greeks. Much credit

that is given to ancient Greece should be shared also by Babylon.

It was from Babylon that Greece obtained the principles of its

civilization, arts and sciences. Even Greek architecture and sculpture

were originally derived from Babylon.
