Iceland Volcano and ‘Recent’ History

Apparently, events over 1,000 years ago are now being considered recent history. According to a Wall Street Journal article from today (unfortunately, behind a pay wall):

Eyjafjallajokull has erupted three times in recent history: in 920, 1612 and 1821-1823.

This expanding awareness of long periods of time is exactly the kind of thing that the Long Now Foundation would be proud of.
