Prehistoric man navigated his way across England using a complex network of hilltop monuments.

New research suggests that they were built on a connecting grid of isosceles triangles that ‘point’ to the next site.

Many are 100 miles or more away, but GPS co-ordinates show all are accurate to within 100 metres.

This provided a simple way for ancient Britons to navigate successfully from A to B without the need for maps.

A 500-year-old ancient drain in Scotland is turning out to be a goldmine for archaeologists.

An initial excavation revealed an arched corridor almost 6ft high, and uncovered pottery fragments and gaming pieces, a complete chamber pot, and other artefacts.

Archaeology professor Steven Driscoll, part of the Glasgow team, said the site was uniquely well preserved.

“What’s unusual is that it hasn’t been messed with. This is a loo that hasn’t been flushed for 500 years. We have a kind of sealed environment, containing artefacts like the earliest known piece of Scottish music, which we found scratched into pieces of slate,” he said.

The remains of various Ice Age animals, including hyenas, deer and woolly rhinos, have been found in a cave in Devon.

The dig at Kents Cavern, Torquay, also unearthed a 15,000-year-old spearpoint, known as a “sagaie”, which is made from reindeer antler from the same era.

The spearpoint is thought to be the first complete one found in the UK.

A few weeks ago I posted an article about a gemstone being found with the face of Alexander the Great carved on it. Unfortunately I did not have a photograph of it at the time. I do now, and it’s exquisite, considering how small the stone is. So I thought I’d share it with you.

“Despite its miniature dimensions – the stone is less than a centimeter high and its width is less than half a centimeter – the engraver was able to depict the bust of Alexander on the gem without omitting any of the ruler’s characteristics” notes Dr. Gilboa, Chair of the Department of Archaeology at the University of Haifa. “The emperor is portrayed as young and forceful, with a strong chin, straight nose and long curly hair held in place by a diadem.”

Experts from the National Museum in Ireland are still trying to figure out how two human feet, dating back 2,000 years, were found in a Dublin attic.

During his examination, Dr Farrell and other scientists concluded the two mummified right feet had come from an adult and from a child. There were no signs of antemortem injuries or cut marks.

The foot of the male adult had part of the lower leg attached although the stretching and tearing of the muscle fibres suggest it had been pulled off a body, said the report.

“It closely resembled a bog body in appearance, as it had the dark brown, almost black colour seen in recent bog bodies such as Oldcroghan Man and Cloneycavan Man,” the report continued.
