Colonizing Greenland and Iceland 1,000 years ago was a big mistake!

New research reveals just how bad an idea it was to colonize Greenland and Iceland more than a millennium ago: average temperatures in Iceland plummeted nearly 6 degrees Celsius in the century that followed the island's Norse settlement in about A.D. 870, a climate record gleaned from mollusk shells shows.

The record is the most precise year-by-year chronology yet of temperatures experienced by the northern Norse colonies, says William Patterson, an isotope geochemist at the University of Saskatchewan in Saskatoon, Canada, who led the new work. The study will appear online in the Proceedings of the National Academy of Sciences.

"We're aware from written documents of the kinds of things that people faced in the North Atlantic over the last 1,000 years," he says. "This is a way to quantify the experiences they had."

JERUSALEM CITY WALL FROM 10TH CENTURY BCE IS DISCOVERED

A section of an ancient city wall of Jerusalem from the tenth century B.C.E. -- possibly built by King Solomon -- has been revealed in archaeological excavations directed by Dr. Eilat Mazar and conducted under the auspices of the Hebrew University of Jerusalem. The excavations in the Ophel area were carried out over a three-month period.

The section of the city wall revealed, 70 meters long and six meters high, is located in the area known as the Ophel, between the City of David and the southern wall of the Temple Mount.

Uncovered in the city wall complex are: an inner gatehouse for access into the royal quarter of the city, a royal structure adjacent to the gatehouse, and a corner tower that overlooks a substantial section of the adjacent Kidron valley.

"The city wall that has been uncovered testifies to a ruling presence. Its strength and form of construction indicate a high level of engineering," Mazar said. The city wall is at the eastern end of the Ophel area in a high, strategic location atop the western slop of the Kidron valley.

"A comparison of this latest finding with city walls and gates from the period of the First Temple, as well as pottery found at the site, enable us to postulate with a great degree of assurance that the wall that has been revealed is that which was built by King Solomon in Jerusalem in the latter part of the tenth century B.C.E.," said Mazar

"This is the first time that a structure from that time has been found that may correlate with written descriptions of Solomon's building in Jerusalem," she added. "The Bible tells us that Solomon built -- with the assistance of the Phoenicians, who were outstanding builders -- the Temple and his new palace and surrounded them with a city, most probably connected to the more ancient wall of the City of David." Mazar specifically cites the third chapter of the First Books of Kings where it refers to "until he (Solomon) had made an end of building his own house, and the house of the Lord, and the wall of Jerusalem round about."

The six-meter-high gatehouse of the uncovered city wall complex is built in a style typical of those from the period of the First Temple like Megiddo, Beersheva and Ashdod. It has symmetrical plan of four identical small rooms, two on each side of the main passageway. Also there was a large, adjacent tower, covering an area of 24 by 18 meters, which was intended to serve as a watchtower to protect entry to the city. The tower is located today under the nearby road and still needs to be excavated. Nineteenth century British surveyor Charles Warren, who conducted an underground survey in the area, first described the outline of the large tower in 1867 but without attributing it to the era of Solomon.

"Part of the city wall complex served as commercial space and part as security stations," explained Mazar. Within the courtyard of the large tower there were widespread public activities, she said. It served as a public meeting ground, as a place for conducting commercial activities and cult activities, and as a location for economic and legal activities.

"The jars that were found are the largest ever found in Jerusalem," said Mazar, adding that "the inscription that was found on one of them shows that it belonged to a government official, apparently the person responsible for overseeing the provision of baked goods to the royal court."

In addition to the pottery shards, cult figurines were also found in the area, as were seal impressions on jar handles with the word "to the king," testifying to their usage within the monarchy. Also found were seal impressions (bullae) with Hebrew names, also indicating the royal nature of the structure. Most of the tiny fragments uncovered came from intricate wet sifting done with the help of the salvaging Temple Mount Sifting Project, directed by Dr. Gabriel Barkai and Zachi Zweig, under the auspice of the Nature and Parks Authority and the Ir David Foundation.

Between the large tower at the city gate and the royal building the archaeologists uncovered a section of the corner tower that is eight meters in length and six meters high. The tower was built of carved stones of unusual beauty.

East of the royal building, another section of the city wall that extends for some 35 meters also was revealed. This section is five meters high, and is part of the wall that continues to the northeast and once enclosed the Ophel area.
