On October 9th in the year 28 B.C., the Temple of Apollo at Delphi was dedicated.
An inscription on the temple said: “Gnothi seauton.” In English, that’s the famous quotation “Know thyself.”
The quote is generally attributed to “The Seven Sages of Greece,” a.k.a. the “Seven Wise Men,” though the words are sometimes attributed to the Greek philosopher Thales or the Greek statesman Solon.
Thales and Solon were two of the “Seven Sages,” a group of 6th century B.C. deep thinkers that also included Periander, Cleobulus, Chilon, Bias, and Pittacus.
Here are some of the other famous quotes and phrases linked to October 9:
• “Better living through chemistry.” - The well known and oft-parodied advertising slogan for the DuPont company, first made famous by its use on the DuPont-sponsored radio show Cavalcade of America, which debuted on October 9, 1935.
• “The Iceman Cometh.” - Title of the play by American playwright Eugene O'Neill (1888-1953) that led to many other “[The something] Cometh” variations – such as "The Diceman Cometh," title of a 1989 performance video by comedian Andrew Dice Clay. O'Neill’s famous play premiered at the Martin Beck Theatre in New York City on October 9, 1946.
