Plaque may provide link with Stonehenge
by Simon at 10:17 02/01/09 (Blogs::Simon)
ARCHAEOLOGICAL director Mike Emery believes new evidence shows a direct link between his dig south of Chester and Stonehenge.

His team has uncovered a 4,500 year-old limestone plaque at the Poulton excavation, bearing a mysterious crisscross pattern.

The closest parallel is a chalk plaque found in 1969 on Salisbury Plain in Wiltshire, just 1km from Stonehenge. The markings were made with a flint tool and flint from Salisbury Plain has previously been found on site.

“There has obviously been contact between the two areas,” said Mike. "There has got to have been trading of some kind."

Full story.

... so that's where I dropped it in a past life! ;-)

"a 4,500 year-old limestone plaque at the Poulton excavation, bearing a mysterious crisscross pattern. [...] The markings were made with a flint tool and flint from Salisbury Plain has previously been found on site. [...] was connected with ritual or ceremonial activities, although its exact purpose is unknown." [from the Chester Chronicle]

Lomas & Knight are of the opinion that certain lozenge shaped markings found on objects of this age may be some kind of latitudinal map, representing the shape of shadows cast by a vertical stick at sunrise & sunset during the two solstices:

"The diagonal cross of the year symbol has four legs which represent the direction of a solstice sunrise or sunset, but the shadows created by the marker poles on an Uriel machine at a solstice will also produce a diamond shape that will vary in its angles according to latitude.

We knew from observations that these lozenges vary according to the latitude at which these readings were taken. At 55 deg north, a regular diamond with four 90 degree angles is produced. At places south of this geometrically primary latitude produce increasingly wider diamonds, and those further north become progressively taller. It therefore occurred to us that these latitude-specific shapes of the lozenges could be used to identify a location in the way that a post code or a zip code does today. If this interpretation is correct, the different lozenges would have described some major megalithic sites." [From Uriel's Machine page 335]

I wonder what definition of sunrise and sunset they're using (first/last gleam; half-disk visible or full disk tangential to and above the horizon). Not that it makes a whole lot of difference, mind you.

The figure for the lozenge angle at 55N based on full disk tangential in the current era is 87° 50' 56", but back in 2500BC it was 90° 15' 42" so it's definitely been exactly 90° (according to any definition of sunrise/sunset) sometime in the last 4500 years.

At Stonehenge, the 2500BC lozenge angle was 80° 54' 56" but its present value is 78° 51' 43".

Shame we don't know (from the report) the angle of the lozenge found at Poulton.

Edit: Here's a closeup of the plaque - it's only a fragment, sadly. From The Poulton Project website
