THE DOG DAYS ARE HERE
At least that’s what the ancients believed.
It’s all in the stars, you see. The Dog Star to be exact. That’s the moniker the ancients gave to Sirius, the alpha star in the constellation Canis Major that is actually the brightest star in the night sky. It really dominates the heavens in summer when it rises and sets with our own sun, two hydrogen-fusing hotties travelling together through the daytime sky. The blue-tinged white-hot Dog Star can even be seen with the naked eye in daylight – and if conditions are right, it literally twinkles with bursts of color.
This alignment of the sun and Sirius is known as conjunction, and it is the span of 20 days before and 20 days after the star’s rising that the Romans – who always did have a way with words – called caniculares dies. Ergo, the dog days of summer were born.
Of course the precise dates vary depending on the latitude of the observer and this is complicated even further by an astronomical oddity known as “precession of the equinoxes” – or the drift of the constellations due to the changing tilt of the earth. Which means that sooner or later the dog days of summer – believe it or not –may actually occur in the dead of winter. But that doesn’t seem to frost anyone. The Old Farmer’s Almanac lists the dog days as July 3 to August 11, and besides, what’s the point of trying to teach an old dog new tricks?
One thing’s for sure – there’s no escape. Unless of course, if you’re my friend Melissa Berman’s dog, Nemo, a mixed breed stray who came home from Tobago with her and spends his days romping in the surf at Montauk. Yes, it is a dog’s life.
Given the fact that Sirius is twice the size of our sun and 20 times as luminous, it’s no wonder that the ancients got it in their heads that the combined heat of the two fiery stars was responsible for the scorching temperatures of summer. Heck, the Greeks dubbed the star that we now know to be 8.6 light years away Sirius, after the word seirios, or “scorching” – and in Latin, the name means “the searing one.”
You could say Sirius is the original hot dog. The star has multi-cultural connections to the canine world. The Egyptians named it Sothis after a mighty and feared goddess who heralded the flooding of the Nile and was symbolized by hunting dogs. The Greeks turned the diamond in the sky into a rock star when they sketched their mythology in the heavens with connect-the-dot characters called constellations, turning Sirius into the hunter Orion’s dog.
Orion has his own tale, of course. Suffice it to say that Sirius is up there with him chasing rabbits and bulls and other celestial creatures that I can never quite make out. The Romans recognized Sirius as top dog and crowned his constellation Canis Major or Big Dog. There’s also a Little Dog, and I have to wonder, is there a message in the stars – why aren’t there any cat constellations?
No matter what, Sirius definitely rules. Human luminaries – Homer, Dante, Milton, Alfred Lord Tennyson, Voltaire and Dickens, to name a few – have all paid literary tribute to Sirius. Even J.K. Rowling acknowledged the power of the name with a character named Sirius Black, who escaped from Azkaban by transforming himself into what else – a black dog.
So what’s a gardener to do during the dog days? Maybe take a cue from Nemo and hide in the hydrangeas.
When I dug up this old English proverb I knew we’d better run for cover:
Dog days bright and clear
Indicate a happy year;
But when accompanied by rain
For better times our hopes are vain
