of early humans. This fear would have been slightly mitigated when it became possible to predict eclipses, something that a number of early cultures sought to do.
A second sort of eclipse, which is seen more often because of the planetary geometry involved, is called a ‘lunar eclipse’ – and in its own way this must have been just as potent and frightening. A lunar eclipse happens when the Moon moves through the shadow of the Earth, so the full Moon is seen to slowly disappear in a clear night sky. (See figure 19, pg 246)
On these occasions the Moon’s face is not totally blotted out by Earth’s shadow, often appearing as a ghostly blood red disc. Even today this is a chilling sight and one can sympathize with people who viewed the event with a sense of foreboding.
Without a good understanding of the planetary cycles involved, eclipses of both sorts could easily appear to be random events and many early cultures sought to discover the patterns involved, probably working on the assumption that understanding inferred a degree of control. This may well have represented the first serious attempts at astronomy. It is known that both the Assyrians and the Babylonians could predict eclipses. In both cases many of the astronomical skills were inherited from the earlier Sumerians and it is highly likely that eclipse prediction already existed before 3,000 BC.
Further west there have been suggestions that some Megalithic monuments were built as eclipse predictors, maybe as early as 4,000 BC. Astronomer Gerald Hawkins in his book
Stonehenge Decoded
used a computer model to demonstrate that Stonehenge in Wiltshire, England, might have been partly built with eclipse prediction in mind. 5
By at least the second millennium BC the Chinese could also predict eclipses. As far back as 2650 BC, Li Shu was writing about the subject of astronomy. Three and a half centuries later, ancient Chinese astrologers had sophisticated observatory buildings, and solar eclipses were considered essential for forecasting the future health and successes of the emperor. These astronomers were keen to be accurate as failure to get the prediction correct was likely to be lethal for them. In one documented case referring to the eclipse of 2136 BC the two astrologers who got it wrong were beheaded. The following recorded their fate: ‘Here lie the bodies of Ho and Hi, Whose fate, though sad, is risible; Being slain because they could not spy Th’ eclipse which was invisible.’ – Author unknown
For thousands of years the Moon was a thing of awe and wonder to human beings across the entire planet and it remains so to millions of people today, despite technological advances and a good understanding of its physical characteristics. For example, the Moon has always been equated with agriculture. Even in some parts of the fully developed world there are farmers and gardeners who would not dream of either planting or harvesting without direct reference to the phase of the Moon or even the part of the zodiac it occupies at any particular point in time. The Moon is the fastest moving astronomical body when viewed from the Earth and appears to pass through all the zodiac signs in only 27.322 days.
Generally speaking, crops were often planted close to the new Moon, so that they could grow with the face of the Moon. Whilst there is no known scientific basis for such ideas, the advice offered is often very specific and doesn’t vary much across the world. Nor does Moon-lore relate only to sowing seeds. For example, it is suggested that when picking apples for immediate eating, it is best to harvest them at the time of the full Moon, though if they are to be stored, the new Moon is preferred, since the apples are believed to be less likely to rot.
Even today the Moon has always been important to humanity and it is central to one of the most important festivals of the Christian religion. Easter, which falls in the early spring in the northern hemisphere, is an
