It starts happening as late summer merges into early fall. Bootes the hunting farmer is in close pursuit of Ursa Major, the Big Bear in the Butler skies.

These two constellations are right next to each other in the early evening northwestern sky and they are easy to see.

Ursa Major, which is Latin for Big Bear, contains the most famous star pattern in the sky — the Big Dipper. The dipper is the brightest part of the bear, outlining the rear end and the tail of the great beast.

The rest of the stars in the Big Bear aren’t nearly as bright, but if you have a dark northern sky and low flat horizon, you may see the skinny triangle that allegedly outlines the Bear’s head and the two faint lines of stars that make up the legs.

Right on the Bear’s tail in the low northwestern sky after evening twilight is Bootes, the hunting farmer that looks much more like a kite than a farmer with a gun.

Arcturus, one of the brightest stars in the sky, is at the tail of the kite. Just follow the arc of the Big Dipper’s handle beyond the end and you’ll run right into Arcturus, a red giant star 36 light-years, or 209 trillion miles, away.

According to legend, Bootes invented the first ox-pulled plow. Before that, people were forced to hand till and plow, making for really long days.

Bootes was the son of Demeter, the goddess of Agriculture. His father was a mortal man that Demeter fell in love with. One thing led to another and oops, Bootes was born to the unwed couple, making him a half god.

Back in those days, these godly love-children were placed into adoption. It was more for convenience than any shame. The gods were much too busy running things to raise their “accidental” children.

The goddess of agriculture placed Bootes with a wealthy farm family and for the first few years everything was great. The crops were good and the profits were high, but then tragedy struck.

Bootes’ foster parents were killed in a car accident on New Year’s Eve. They willed all of the money and the farm to Bootes and his older half-brother, who served as executor of the will because he was their oldest son.

Things would have been OK, except that Bootes’ big brother was a crook. About a month after the terrible accident he took all of his parent’s money out of the bank, and he and his girlfriend were off on a global spending spree.

Bootes was on his own on the farm, broke and unaware he was half divine because he was adopted as a baby. It was a real struggle.

That spring, Bootes had to do all the tilling himself by hand because he had no money for hired help. He kept thinking, there’s gotta be a better way to do this.

It was a combination of his half godliness, his ingenuity and his desperation that led him to invent the plow that could be pulled by an ox rather than a person.

After he worked out all of the bugs, Bootes really had something. Not only was he able to plow his own fields in much less time, there was much less wear and tear on his body.

Other farmers saw Bootes with this new invention and wanted Bootes to build ox plows for them. Word spread even farther and pretty soon, Bootes had a booming business. He sold the farm and concentrated on his plow business. He was loaded.

As the business got better and better, he was able to take time off to hunt and fish, which he did a lot of before his foster parents were killed.

The gods on Mount Olympus got word of this and eventually it reached Demeter, his real mother. She was so proud of her son, and she was especially proud of what he did to improve farming because, after all, she was the goddess of agriculture.

When Bootes was getting on in years, Demeter decided to give her son the ultimate reward. She plucked him off the ground and placed his body in the stars as the constellation we see today.

Every summer and fall Bootes is having the ultimate hunting experience. He gets to hunt the Big Bear, Ursa Major. He couldn’t be happier, and it’s said Bootes is one of the happiest constellations in the sky.

In the next month or so, Bootes and Ursa Major will sink lower in the northern sky as autumn begins. According to lore, that’s because Bootes has nailed the bear with his arrows and the bear sinks to the ground with Bootes in hot pursuit.

It’s also said the reason the leaves on the trees turn to shades of red every fall is because the Big Bear is bleeding. All right, the lack of chlorophyll may have something to do with it, too.

Ursa Major is one tough bear though, because every winter he manages to lick his wounds and recover in time to rise up again, high in the northeastern skies of spring, with Bootes right on his tail. The great hunt goes on and on and on.

Next Saturday the new crescent moon will have a spectacular conjunction with the bright planets Venus and Jupiter in the very early evening western sky during twilight. Don’t miss it.
