Study suggests Seahenge was built to control climate change

Published

on

A recent study published in GeoJournal proposes that Seahenge was built to conduct rituals aimed at prolonging the summer during the extreme climatic changes of the 3rd millennium BC.

Seahenge, also known as Holme I, is a prehistoric timber circle monument located on the English coast in the county of Norfolk.

Seahenge, along with the nearby timber circle, Holme II, was built during the early Bronze Age around 2049 BC. Seahenge consists of fifty-five small split oak trunks forming a circular enclosure with an upturned tree root in the centre.

The monument would have been positioned in an area protected from the sea by sand dunes and mud flats.  This swampy area created a layer of peat which slowly covered the timbers, protecting them from decay.

Over the centuries, changing sea levels have meant that the inland monument is now located on the coast, which has become exposed due to eroding sand and peat.

The study also looked at Holme II, a much larger monument consisting of two concentric timber circles surrounding a hurdle-lined pit containing two oak logs.

Previous theories propose that Seahenge and Holme II were constructed around the same time, either as burial markers or for sky burials, where the deceased would be placed in the monument to be gradually consumed by carrion-eating birds.

Study author, Dr Nance, proposes an alternative explanation. He suggests that both monuments were constructed during a bitterly cold climatic period for rituals, intended to extend the summer and the return of warmer weather.

Dr Nance explains: “Dating of the Seahenge timbers showed they were felled in the spring, and it was considered most probable that these timbers were aligned with sunrise on the summer solstice.”

“We know that the period in which they were constructed 4,000 years ago was a prolonged period of decreased atmospheric temperatures and severe winters and late springs placing these early coastal societies under stress.

“It seems most likely that these monuments had the common intention to end this existential threat but they had different functions.”

He points to the alignment of Seahenge with sunrise on the summer solstice and suggests that its function was to mimic the ‘pen’ described in folklore for an unfledged cuckoo with the intention to keep the bird singing and thereby extend the summer.

“Summer solstice was the date when according to folklore the cuckoo, symbolising fertility, traditionally stopped singing, returned to the Otherworld and the summer went with it,’ Dr Nance added.

“The monument’s form appears to imitate two supposed winter dwellings of the cuckoo remembered in folklore: a hollow tree or ‘the bowers of the Otherworld’ represented by the upturned oak-stump at its centre.

“This ritual is remembered in the ‘myth of the pent cuckoo’ where an unfledged cuckoo was placed into a thorn bush and the bird was ‘walled-in’ to extend the summer but it always flew away.”

For Holme II he points to legends of ‘sacred kings’ described in Iron Age Ireland and northern Britain who were sacrificed if misfortune fell on the community, as happened at Holme-next-the-sea, in an attempt to appease the goddess of Venus to restore harmony.

He said: “Evidence suggests that they were ritually-sacrificed every eight years at Samhain (now Halloween) coincident with the eight-year cycle of Venus.

“The fixtures in Holme II that were thought to hold a coffin, are orientated towards sunrise on Samhain in 2049 when Venus was still visible.

“Both monuments are best explained as having different functions and associated rituals, but with a common intent: to end the severely cold weather.”

Egypt’s first pyramid was constructed using hydraulic lift

Published

By

A recent study, published in the journal ResearchGate, proposes that the Pyramid of Djoser could have been constructed using hydraulic lift.

The Pyramid of Djoser, also known as the Step Pyramid, is a proto-pyramid built as the final resting place of Djoser, the first or second pharaoh of Egypt’s 3rd Dynasty (2670–2650 BC) during the Old Kingdom period.

The pyramid rises from the Saqqara plateau in six steps to a height of around 60 to 62 metres, serving as the centre of a vast mortuary complex.

Due to the absence of authentic sources from the pyramid architects’ working sphere, there is currently no confirmed comprehensive model for the method used in the pyramid construction.

The prevailing theory suggests that the heavy stone blocks were transported on apparatuses such as rollers, and raised to height using a series of ramps.

In the study, a survey of watersheds near to the pyramid indicate that the Gisr el-Mudir (enclosure) has features of a check dam for trapping sediment and water. Furthermore, the topography beyond the “dam” shows a possible ephemeral lake west of the Djoser complex, and water flow inside the moat surrounding it.

The study authors explain: “In the southern section of the moat, we show that the monumental linear rock-cut structure consisting of successive, deep compartments, combines the technical requirements of a water treatment facility: a settling basin, a retention basin, and a purification system.”

Based on this finding, the study proposes that the Gisr el-Mudir and moat’s inner south section worked as a unified hydraulic system for regulating flow and improving water quality. In addition, the pyramid’s internal architecture is consistent with a hydraulic elevation mechanism never reported before.

“The ancient architects likely raised the stones from the pyramid centre in a volcano fashion using the sediment-free water from the Dry Moat’s south section. Ancient Egyptians are famous for their pioneering and mastery of hydraulics through canals for irrigation purposes and barges to transport huge stones. This work opens a new line of research: the use of hydraulic force to erect the massive structures built by Pharaohs,” said the study authors.

Please note: This study was submitted to PLOS ONE on December 7, 2023. After two rounds of review by peers, the paper was formally accepted by PLOS ONE on June 27, 2024. Since July 23, 2024, it has been the subject of new consultations and review by the PLOS ONE Editorial Board.

Lost splendour of the Great Synagogue of Vilna rediscovered

Published

By

Constructed between 1630 and 1633 in a Renaissance-Baroque style, the Great Synagogue of Vilnius served as the religious centre of a complex of synagogues, mikvahs, and community institutions devoted to Torah study in Vilnius, Lithuania.

According to a press statement by the Israel Antiquities Authority (IAA): “The Great Synagogue of Vilna was the beating heart of the Lithuanian Jewry, which included 12 synagogues and study houses, the community council building, the home of Rabbi Eliyahu – the Vilna Gaon, Kosher meat stalls, the famous ‘Strashun’ library, a bathhouse and more.”

During World War II, the synagogue was looted, burned, and partially destroyed by the Nazis in the holocaust. Soviet authorities completely demolished the remaining structure to build a school, intending to prevent any future restoration of Jewish worship.

Only three original pieces of the synagogue survived the destruction: a door of the Holy Ark, a reader’s desk, and a bas-relief with the Ten Commandments, which are now on display at the Vilna Gaon Jewish Museum.

In a recent study conducted by the IAA, the Association of Lithuanian Archaeology, the Good Will Foundation, and the Jewish Community of Lithuania, archaeologists have rediscovered traces of the synagogue’s decorated walls and remnants of flooring with red, black, and white floral patterns that paved the main hall.

Excavations also uncovered huge water reservoirs to feed halachically pure water to the mikva’ot, and one of the giant pillars that surrounded the Bimah (prayer platform).

Dr. Jon Seligman from the IAA and Justinas Rakas from the Lithuanian Archaeological Society, said: “The magnificent remains we are rediscovering bring back moments in the life of a lost vibrant community.”
