A new analysis of 1st Temple-era artifacts, magnetized when Babylonians torched the city, provides a way to chart the geomagnetic field – physics’ Holy Grail – and maybe save Earth The Bible and pure science converge in a new archaeomagnetism study of a large public structure that was razed to the ground on Tisha B’Av 586 BCE during the Babylonian conquest of Jerusalem. The resulting data significantly boosts geophysicists’ ability to understand the “Holy Grail” of Earth sciences — Earth’s ever-changing magnetic field. “The magnetic field is invisible, but it plays a critical role in the life of our planet. Without the geomagnetic field, nothing on Earth would be as it is — maybe life wouldn’t have evolved without it,” Hebrew University Prof. Ron Shaar, a co-author of the study, told The Times of Israel. In the new study published in the PLOS One scientific journal, lead author and archaeologist Yoav Vaknin harvested data from pieces of floor from a large, two-story building excavated in the City of David’s Givati parking lot. Minerals embedded in the dozens of floor chunks were heated at a temperature higher than 932 degrees Fahrenheit (500 degrees Celsius) and magnetized during the slash and burning of ancient Jerusalem, and therefore offered up geomagnetic coordinates.

An iron helmet that was discovered in Yarm, North Yorkshire, during sewer work in the 1950s has been confirmed to be an extremely rare Viking-era helmet, only the second nearly complete Viking helmet in the world and the first and only one found in Britain.

It was referred to as the Viking helmet from the beginning, but its real age has been an open discussion since its find. It has design elements found in earlier forms from the Anglo-Saxon and Vendel era, and because the only other helmet in the world confirmed to date to the Viking era, the Gjermundbu Helmet found in Haugsbygd, Norway, in 1943, was not a direct comparison, it was difficult to conclusively identify the Yarm Helmet as an Anglo-Scandinavian piece. A new study by Durham University researchers has used recent archaeological finds and analysis of the iron and corrosion products to narrow down its age of manufacture. It is indeed an Anglo-Scandinavian helmet made in northern England in the 10th century.
