Giant petroglyph carving found hidden under moss in Sweden
Archaeologists from the Foundation for Documentation of Bohuslän’s Rock Carvings have discovered a giant petroglyph carving in the Swedish province of Bohuslän.
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading as a form of rock art.
Previous studies suggest that the tradition of carving petroglyphs was evidence for religious practices, however, more recent research proposes that they are not only depictions of cultic rituals but also as source material for cultural history and social hierarchies.
The archaeologists were surveying a rock slab in a farm pasture when they noticed a tiny part of a ship beneath layers of moss.

Removing the moss revealed a 15-metre-long petroglyph consisting of 40 figures showing ships, horses, people, and chariots. In total, the researchers have identified thirteen ships, nine horses, seven people, and four chariots.
“These are very large things, including a two-metre ship and a person over one metre in height. The figures are well carved and deep. The motifs are not unique, but the location on an almost vertical outcrop is unusual”, says archaeologist Andreas Toreld.
The carving has been dated to around the 7th–8th centuries BC during the peak of petroglyph carving in the Nordic Bronze Age.
Bohuslän has a high concentration of similar petroglyphs, where examples of people, agriculture and stock raising, hunting and fishing, cult and religion (e.g. the Sun cross), carts, ships, and weapons can be found throughout the province.
Due to the linear alignment of the figures, the researchers suggest that they were carved by artisans while stationary on a boat. At the time, the outcrop was part of an island, in which the petroglyph was carved just above the waterline that was darkened by cyanobacteria.

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.

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.”
