Dog Days and Dog Lore

The other day while browsing through The Old Farmer's Almanac, I saw this notation for July 3rd: Dog Days Begin. I experienced the dog days quite viscerally today myself. I was out walking around during my lunch and noticed that it was blindingly bright, unpleasantly hot, and extremely humid. I felt a little stupefied. 

The dog days of summer begin on July 3rd and end on August 11th. They are said to be the hottest days of summer in the Northern Hemisphere, and get their name from the star Sirius, which rises in conjunction with the sun during this time. Sirius is part of the constellation Canis Major (Latin for the Greater Dog), which follows Orion through the sky.

The ancient Greeks were the first people to call this time of year the dog days. For example, in The Iliad, the poet Homer has the following to say: 

...all radiant as the star which men call Orion's Hound, and whose beams blaze forth in time of harvest more brilliantly than those of any other that shines by night; brightest of them all though he be, he yet bodes ill for mortals, for he brings fire and fever in his train... (Homer, The Iliad, Book 22, translated by Samuel Butler)

Some Greeks tried to appease Sirius the Dog-star (and the heat it brought) with sacrifices, a practice taught to them by Aristaios, the divine son of Apollo. 

The Dog-star Sirius was scorching the Minoan Islands from the sky, and the people could find no permanent cure for the trouble till the Archer-King Apollon put it in their heads to send for Aristaios. So, at his father's command, Aristaios ... left Phthia, and settled in Keos. He raised a great altar to the Rain-god Zeus and made ritual offerings in the hills to the Dog-star and to Zeus himself, the Son of Kronos. In response, Zeus gave his orders - and the Etesian Winds refresh the earth for forty days. The priests of Keos still make yearly sacrifice before the rising of the Dog. (Apollonius Rhodius, Argonautica)

The ancient Romans also believed that Sirius rising created the hottest days of summer. Here is what Pliny the Elder wrote on the matter:

Who is there that does not know that the vapour of the sun is kindled by the rising of the Dog-star? The most powerful effects are felt on the earth from this star. When it rises, the seas are troubled, the wines in our cellars ferment, and stagnant waters are set in motion... There is no doubt that dogs, during the whole of this period, are peculiarly disposed to become rabid. (Pliny the Elder, Natural History, Chapter 40)

An interesting side note about Pliny the Elder: he died while trying to save people from the eruption of Mount Vesuvius that destroyed Pompeii and Herculaneum. His Natural History was only published after his death. 

From the Greeks and Romans, the concept of the dog days has been passed down to us. I think most modern Americans are still familiar with the idea, even if they don't know the exact dates that comprise the dog days. They might also know the song by Florence and the Machine, "Dog Days Are Over." Fire, fever, rabid dogs, troubled seas, and stagnant waters. The dog days don't sound like much fun. No wonder Florence is so glad they're over. 

I can hear someone out there saying, "But I love summer! Summer is awesome! The beach! Cookouts! School vacation! Trips to Europe!" Yes, all those things are amazing parts of the summer season. We don't live in the ancient Mediterranean world, where summers were inescapably hot and hellish. We live in a world with ice cream and air-conditioning. Of course, with climate change, people around the world are once again experiencing the sometimes terrifying power of summer - wildfires, heatwaves, and droughts are increasing every year. And not everyone is fortunate enough to have air-conditioning and ice cream.

An interesting side note about trips to Europe: I read today that an American tourist was injured when he tried to retrieve his phone after dropping it into Mount Vesuvius. Happily, the volcano was not erupting at the time.

Thinking about the dog days made me curious to see if I could find some New England lore about dogs. I found a few intriguing tidbits in What They Say in New England (1896), Clifton Johnson's collection of local folklore. Although Johnson notes that it was considered healthier to have dogs than cats as pets, he does include some sinister lore about dogs. For example, he writes about a dog in Hadley, Massachusetts that howled every night when the 9:00 pm church bell rang. The citizens of Hadley assumed this was an omen of something bad, but they weren't quite sure what. 

They probably thought the dog's howling foretold someone's death, because Johnson also writes that it was believed a dog howling under a window foretold a death in the house. 

There was a dog went and howled under the window of a house up near where I lived. He howled and howled; and they drove him off, but no sooner done it than he was right back again. And in two or three days an old lady that lived there died. (Clifton Johnson, What They Say in New England (1896))

Johnson also writes about a related belief. If a dog howls in the yard, the first person who walks through the front door will soon die. Dogs are man's best friend, but also an omen of doom. I suppose they're like the dog days of summer in that respect. Some people think they're lovable and fun, while others look at them with dread.
