This raises the question of why Greenland is to be counted as part of
North America and Iceland is not. Both are islands. Part of Iceland is
"American" geologically speaking--on the American side of the division
between the plates.
Count the relevant part of Iceland, and the date goes back to
870--earlier if you accept the evidence for previous Irish occupation.
Don't count Greenland and the date moves forward to about 1000, when
Leif Ericsson visited Vinland.
Which is still closer to Augustus than to us.

I realized, after posting, that I had misremembered the previous
posts--I thought the claim was being made for Greenland, not for
Vinland. If you count Greenland as part of North America, that moves the
date back almost as far as if you count Iceland.
It was.
But *my* original request wasn't just for an event that was closer to
a seemingly-very-long-ago event than to the present, but for one that
was also closer to a seemingly-very-recent event than that seemingly-
very-recent event was to the present.
I gave the example of the publication of _Gone With the Wind_ being
closer to the Civil War than to the present, but closer to the Moon
landings than the Moon landings are to the present.
Another example is that the JFK assasination is closer to World War I
than to the present, but is closer to the Challenger explosion than
the Challenger explosion is to the present.
The seemingly-long ago event has to be not more than four times longer
ago than the seemingly-recent event. Here's a table (as of January 1,
2010, which is less than seven weeks away):
2005:1990 2000:1970 1995:1950 1990:1930 1980:1890 1970:1850 1960:1010
1950:1770 1925:1670 1900:1570 1850:1370 1800:1170 1700:770 1600:370
1508:2
(Actually, this table just looks at January 1st of each year, and
ignores leap years and calendar shifts.)
For instance there's an event which is closer to 1/1/1890 than to the
present, but closer to 1/1/1980 than 1/1/1980 is to the present. Or
rather, there will be in seven more weeks.
Yes, I was considering the Viking arrival at Greenland as the European
discovery of North America.

Googling around a little...
Landnamabok says that Erik the Red started the settlement of Greenland
fifteen years before Iceland went Christian, which happened in the year
1000. Herjolf Bardarson was one of those who went with him. His son
Bjarni was in Norway at the time, and got back to Iceland that summer.
Discovering, to his surprise, that his father had left, he decided to
follow him.
He managed to miss Greenland on the first pass and spotted some land
west of it, now believed to have been the coast of North America.
On the other hand, as best I can tell Landnamabok is believed to have
been compiled in the early 12th century. So presumably the information
was initially preserved only in oral tradition.
The continental divisions are fairly arbitrary in some cases (the best
example being Papau New Guinea divided so one section of it is part of Asia
while the other section is part of Australia / Oceanea). As well, different
countries deliniate the continents differently.

Yes, and based on the most recent carbon dating, some scientists put
the settlement of Iceland as far back as ca 670.
The world was divided into continents long before the plate-tectonics
theory was accepted.
Let´s not confuse plates with continents (or is India not a part of
Asia?)

I think the division is usually cultural. Greenland was and is
inhabited by Eskimos. Iceland was not.
Irish or Norse?

No, it is much too soon for that. My guess is that it was a mixture,

Yes, but the plate tectonics theory only got accepted in the last
couple of decades, people used to divide the world into continents
thousands of years before that so "geologically speaking" has got
nothing to do with anything.
Or do you not consider India to be a part of Asia? It is on a seperate
plate.

http://www.daviddfriedman.com/ http://daviddfriedman.blogspot.com/
I thought the usual theory was that the earlier Irish settlers, if they
existed, left when the Norse showed up c. 870 A.D., and the Irish
contribution to Icelandic genetics was mostly via Irish slave women and
some Norse-Irish from the Norse settlements in Ireland.
If so, then any settlement back in c. 670 would be irrelevant to the
descent of modern Icelanders and could--I was guessing probably
would--have been entirely Irish, possibly monks looking for a suitably
lonely hermitage.
In 670 A.D.? Isn't that a little early?
It is thought that the Norse started to move about the North sea
around 600 AD so it is not that early.
Well, rather vice versa, a few slaves and most as mixed Norse/Celtic.
Slaves in Iceland were of a very mixed origin, some were Celtic, some
Norse and some Wendic or other Slavic origin.
The story of Irish hermits preceding the Norse settlement is not
considered very likely.
Speaking of "subcontinents".
Icelandic geologists now regard the upper parts of Árnessýsla/
Rangárvallasýsla in the south of Iceland as being a seperate plate,
called the Hreppar plate. Thingvellir is no longer regarded as being
on the European/American boundary but the Hreppar/America boundary.
I may be misremembering, but I thought the big genetic study had found
much more Irish ancestry in the female line--either mitochondrial DNA vs
nuclear, or X vs Y, or something else. If so, that would support the
"female Irish slave" version.

That's terrible. I thought that Thingvellir, where all the interesting
stuff happened, being located precisely on the boundary between America
and Europe was a perfectly proper accident--almost evidence for divine
intervention.

I know the ancient Greeks had the concepts of Europe, Asia, and
Africa, though those concepts have since been extended until they
reached the oceans.
Or the version where the young Norwegian male moves to Scotland/
Ireland to get himself a bride and starts a family.
By the time they reach Iceland he may be the only Norse in an
otherwise Scottish/Irish family.
During the eruptions of the Krafla area in North-Iceland scientists
used observations of the surface movements to augment their
understanding of plate tectonics. That was in 1975-1984 and plate-
tectonics was not a generally accepted science until after that time.
I am not sure of that, there were no Inuit in Greenland (except some
that may have been in the extreme north) when it was settled by the
Norse. The Norse Greenlanders did not come into contact with Inuits
until ca 1200.
The Wikipedia article on Greenland's prehistory indicates that the
Inuit have been there for a very long time, but were not in the south
western coast areas settled by the Norse at the time they arrived. The
Thule Culture Eskimos were gradually moving down the coast, and their
expanding territory collided with the Norse about the time the
Norseman's colonies were failing.

When did they start being able to track continental drift from one
day to the next by observing quasars with radio telescopes? I know
quasars were discovered 46 years ago.
I remember reading that continental drift was quackery, but I often
read books that were a few years out of date.

As I read those, the theory wasn't widely accepted until well into the
sixties or perhaps a little later, although the idea was being argued
earlier than that. So about forty years ago.
And as *I* read those, Continental Drift was well established. The
mechanism, Plate Tectonics, was not necessarily.

"But without detailed evidence and a force sufficient to drive the
movement, the theory was not generally accepted:the Earth might have a
solid crust and a liquid core, but there seemed to be no way that
portions of the crust could move around."
"The first evidence that the lithospheric plates did move came with the
discovery of variable magnetic field direction in rocks of differing
ages, first revealed at a symposium in Tasmania in 1956. Initially
theorized as an expansion of the global crust,[11] later collaborations
developed the plate tectonic theory, which accounted for spreading as
the consequence of new rock upwelling, but avoided the need for an
expanding globe by recognizing subduction zones and conservative
translation faults. It was at this point that Wegener's theory became
generally accepted by the scientific community."
So it becomes generally accepted only at some point after 1956, when
"later collaborations developed the plate tectonic theory ... ."
My rcollection is that it was appearing in respectable popular science
books somewhere around that time, as the newly accepted theory.

"Continental drift is the movement of the Earth's continents relative to
each other. The hypothesis that continents 'drift' was first put forward
by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in
1912. However, it was not until the development of the theory of plate
tectonics in the 1960s, that a sufficient geological explanation of that
movement was found."
"The hypothesis that the continents had once formed a single landmass
before breaking apart and drifting to their present locations was fully
formulated by Alfred Wegener in 1912.[2] Although Wegener's theory was
formed independently and was more complete than those of his
predecessors, Wegener later credited a number of past authors with
similar ideas:[3][4] Franklin Coxworthy (between 1848 and 1890),[5]
Roberto Mantovani (between 1889 and 1909), William Henry Pickering
(1907)[6] and Frank Bursley Taylor (1908)."
It seems to me that you are confusing the notion of continental drift -
which has a long history - with the discovery of the explanation, which
is plate tectonics.
Keith said it was considered "quackery." That is clearly not the case.

"My idea of gun control is a steady aim."

No. I am saying that the notion of continental drift, although it has a
long history, was not generally accepted until plate tectonics was
available to provide a mechanism. "It was at this point that Wegener's
theory became generally accepted by the scientific community."
The claim, I think by you although I'm not sure, was:
"Wikipedia seems to indicate that Continental Drift was well established
before you were born."
"Well established" doesn't merely mean that someone has proposed the
theory but that it is widely accepted.
We were taught about continental drift in Geography class at school in
the late Sixties. Memory fades but I don't recall it being particularly
controversial. I don't think the plate tectonics mechanism was mentioned
in the coursework though, just the fact of continental drift happening.
By that time accurate surveying techniques had shown continental drift
in action so it was not unsupported theoretical speculation.

There were a lot of observable phenomena that science had no
explanation for until the knowledge base was expanded. I had an old
"children's guide to science" book from the 1920s that explained the
energy output of the Sun in terms of waggonloads of coal burnt per
second -- I can't recall the number but it was lots and lots. At the
time the book was written science didn't know HOW stars generated so
much energy as atomic theory hadn't advanced sufficiently to model
fusion processes, but we certainly knew stars did generate energy and we
could even measure the output levels to a large degree of accuracy.

When I did a geology O-level in 1969, continental drift was not mentioned
at all. Indeed, the implication of much of the course was that the
continents did not drift.
My (geologist) wife was in college in the early seventies, and remembers
continental drift being seen as something pretty new then.
I have vague memories of an exhibit on geology in the Field Museum in
Chicago that we saw about twenty years ago, and my wife commenting that
it had apparently been put together before continental drift had become
accepted. I don't know how old the exhibit was.
Coincidentally, I've just finished reading the 1959 revised edition of
George Gamow's Biography of the Earth :-)
It was revised from the 1941 edition, as the solar collision theory of
the origin of the planets had fallen out of favour.
It does feature some limited continental drift - the theory was that
the continents had broken up and drifted into their current positions
fairly early in the Earth's history, and then were locked in place as
the rest of the crust froze, before the moon and the oceans were
formed.
It didn't really strike me as credible, but it was certainly an
interesting half-way house towards the modern continental drift
theory.

Dan, ad nauseam
I have a book from 1914 that says that the sun's energy probably comes
from radioactivity. That's not quite right, but it's much closer to
right than the 19th century ideas that the sun was a coal fire or was
heated by contraction or by meteors and comets falling into it. It
was realized that the if any or all of those were the source of the
sun's energy, it couldn't be more than a few tens of thousands of
years old, nor could it last more than a few tens of thousands more
