According to Herodotus, the appearance of the eclipse was interpreted as an omen and, interrupted a battle in a long-standing war between the Medes and the Lydians. The fighting immediately stopped and they agreed to a truce. Because astronomers can calculate the dates of historical eclipses, Isaac Asimov described this battle as the earliest historical event whose date is known with precision to the day and described the prediction as the birth of science.
The Mechanics of a Monumentally Difficult Prediction
The reason this astronomical event is thought of as being so important is that predicting a solar eclipse, compared with a lunar eclipse, is exceptionally difficult. The astronomer must not only calculate when it will occur but, where on Earth’s surface it will be visible […]. [In] a lunar eclipse, the moon passes through the Earth’s sun shadow and the phenomena is visible on the whole side of the Earth that is in night-time […]. [They] often last longer than an hour. In solar eclipses, however, the moon’s shadow falls across the Earth in a comparatively narrow path, with a maximum duration, at any given location, of about 7 1/2 minutes.
[What] makes Thales’ prediction [an] historical mystery is that historians know early Greeks, at large, didn’t have this essential lunar data and there are no other records of Greek astronomers in this period accurately predicting any other eclipses. Thus, it is thought by historians that the only place Thales’ advanced astronomical knowledge could have come from was Egypt. [It’s] known [that] Thales studied Egyptian techniques for measuring sections of land with rope […].
Returning [to] the war (mentioned above), after 15 years of fighting, on May 28, 585 BC, the armies of King Aylattes of Lydia were in battle with the forces of King Cyaxares of Medes (or, possibly, Astyages, his son), near the River Halys in what is, today, central Turkey. Chroniclers noted the heavens darkening and soldiers on both sides laying down their weapons in awe of the spectacle […]. [The] event ended both the battle and the war.
[A] Wired article says this famous astronomical event has been debated by hundreds of scholars for nearly two millennia and that some authorities believe Thales’ eclipse may have occurred 25 years earlier in 610 BC. But, the reason most agree with the 585 BC date is the record of the famous battle in Asia Minor ending when the day was suddenly turned to night.
A while back, I asked Mani @ Think & Explore to draw Alan Watts. He is a gifted artist and this is a perfect example. Go visit and see how he drew it. Thanks, Mani! ~Vic
Hi all, I am back with a new pencil sketch today! 😃 There’s a specialty for this one. Some time back, this picture (of Alan Watts) was requested by blogger The Hinoeuma (blog Cosmic Observation) as a suggestion to my next to draw list. I took the suggestion and worked on the sketch recently. […]
July 12th is another very busy ‘National Day’ with five celebrations. Simplicity Day is observed on the birthday of Henry David Thoreau. He was born on this day in 1817. As a philosopher, he believed in living a simple life:
“In proportion as he simplifies his life, the laws of the universe will appear less complex and solitude will not be solitude, nor poverty poverty, nor weakness weakness.”
He was a world-renowned author, historian, abolitionist, tax resister (my hero!), a surveyor, criticized over-development, preferred the natural ways and transcendentalism and, was a friend of and mentored by, Ralph Waldo Emerson. Born nearly 100 years prior to Alan Watts, the two could have been contemporary peers.
In our overly busy lives, steeped in political battles, materialism, social media madness and the struggle to survive, slowing down, disengaging and walking in nature can be a refreshing break. De-cluttering and simplifying one’s life can, ultimately, bring peace and balance.
