origin of the term dog days of summer
Dog days The English name is a calque of the Latin dies caniculares (lit. "the puppy days"), itself a calque of the Greek kynádes hēmérai (κυνάδες ἡμέραι, "dog days").[1] The Greeks knew the star α Canis Majoris by several names, including Sirius (Σείριος, Seírios, "Scorcher"), Sothis (Σῶθις, Sôthis, a transcription of Egyptian Spdt), and the Dog Star (Κῠ́ων, Kúōn).[2] The last name reflects the way Sirius follows the constellation Orion into the night sky.[3]
Hot dog According to a myth, the use of the complete phrase hot dog in reference to sausage was coined by the newspaper cartoonist Thomas Aloysius "Tad" Dorgan around 1900 in a cartoon recording the sale of hot dogs during a New York Giants baseball game at the Polo Grounds.[21] However, Dorgan's earliest usage of hot dog was not in reference to a baseball game at the Polo Grounds, but to a bicycle race at Madison Square Garden, in The New York Evening Journal December 12, 1906, by which time the term hot dog in reference to sausage was already in use.[21][26] In addition, no copy of the apocryphal cartoon has ever been found.[27]
