1000xLog10(5) = c.699 because 10^0.699 = c. 5.
So, what happened in the year 699 A.D.?
The Anglo-Saxon Chronicle: This year the Picts slew Alderman Burt.
Whoever he was. I hope it was quick. If they'd left drawings of it, we might have said it was a Picturesque death.
Abu Hanifa Al-Numan was born in 699 (according to Medieval Islamic Civilazation: A-K by Josef W. Meri and Jere L. Bacharach), and began the Hanifa school of Islamic legal thought. He declined a judgeship under the last of the Umayyid caliphs, who had him whipped for the refusal. He died in prison in Baghdad at age 70. He was thought to have met at least four of the "companions of Mohammed" and so his thinking has great stature in the Islamic world. Rough way to go, though.
In 699, the duke of Bavaria gave an abandoned monastary near the abandoned Roman town of Luvavum to a saint I'd never heard of named St. Rupert. He became the city's bishop, and things started getting better. Today we know that city as Salzburg (which it named itself about 50 years later). Mozart was born in Salzburt in 1756, 20 years before the American Revolution. I just checked, and that year will show up later when I do the Log of History for the number 57! (Not 57-factorial, just 57.)
The Log of History so far:
1000xLog(1) = 0 Jesus' Birth.
1000xLog(2) = c.301 Armenia becomes Christian; Diocletian fixes prices.
1000xLog(3) = c.477 Zeno informed Rome no longer has an emperor; Shaolin Temple built.
1000xLog(4) = c.602 First Anglo-Saxon laws recorded; Byzantine Emperor Maurice murdered.
1000xLog(5) = c.699 Beginning of Salzburg; Hanifa founder born.
