You may be done with the past, but the past is not done with scenarios.
Scenarios writ by history on this date:
44BC: Casca, Brutus and Cassius decide that Mark Antony can live. Shakespeare is grateful.
1381: Chioggia forms an alliance with Zadar and Trogir (no, I'm not making those last two names up or taking them from Lord of the Rings, they are coastal cities in present-day Croatia) against Venice. Which, when you consult maps, is sort of like Staten Island forming an alliance against Manhattan with Halifax, Nova Scotia and St. John, New Brunswick.
1794: Eli Whitney receives a patent for his cotton gin, sentencing generations of students to memorize this fact without having the slightest idea what a cotton gin could possibly be.
1885: Gilbert & Sullivan's "Mikado" premieres in London, putting the lie to Karl Marx's epigram that "History repeats itself, first as tragedy, then as farce." In this case the farce comes first, followed some 52 years later by tragedy, and later as manga cartoons.
1942: Penicillin is first successfully used in the United States by Drs. Orvan Hess and John Bumstead to treat Anne Miller. Probably not the dancer/actress.
1994: Linux 1.0.0 is introduced.
