We mark certain days of the year with ‘On This Day’ posts, recalling events associated with them.
Our events are grouped under two calendars. The Gregorian ‘New Style’ (NS) is the worldwide calendar first issued at Rome in 1582. On that calendar, today is September 12. The Julian ‘Old Style’ (OS), also issued at Rome but in 46 BC, was used in Roman Britain and then in England from Anglo-Saxon times until 1752. It is still used today by roughly 100 million Orthodox Christians worldwide. On that calendar, today is August 30.
Today
Remembered as the inspiration of the famous Olympic road race, but much more important than that.
The Battle of Marathon is remembered today chiefly as the inspiration for the modern road race. But its real significance was that it kept Greece from being asset-stripped by Persia, and so helped to save Western civilization.
