The Cochno Stone was discovered in 1887 but was buried in 1965 by to protect it from damage by vandals
It has remained buried for 50 years on the edge of a tatty council housing estate near Clydebank, Scotland
High resolution scan will be used to record the surface of the 42 feet long slab of rock before it is reburied
Archaeologists hope to gain new insights into the carvings and perhaps unravel their mysterious meaning
Discovered in 1887 by the Reverand James Harvey on a section of farmland near Clydebank in West Dunbartonshire, the Cochno Stone caused a sensation when it was unearthed.
It began to suffer vandalism, however, after the local council built the Faifley housing estate on the neighbouring land.
Archaeologists feared the ancient rock carvings would be destroyed as people walked over the rock and added their own carvings to it.
In 1965 archaeologist Ludovic Maclellan Mann decided to bury it under several feet of soil to protect it from further damage.
The new project will aim to use the high resolution images to unpick which of the carvings were caused by vandals before it was buried and which belong to the original.
Little is known about what cup and ring symbolise, but they are found in many rock art sites around Europe.
Some experts believe they may have been an ancient form of writing or recording events or perhaps a unit of measure.
Others have suggested they may be artworks that symbolise life and death. It is possible the Cochno stone was used in ancient Stone Age ceremonies.
Ferdinand Saumarez Smith, from the Factum Foundation for Digital Technology in Conservation, which is carrying out the imaging, said the images will also be used to create a replica of the stone slab that will go on display.
WHAT ARE CUP AND RINGS
Cup and ring marks are a form of prehistoric art found widely through out the world.
They consist of a round indentation – the cup – surrounded by a series of concentric circles that look like ripples on water.
The symbols date back to the Neolithic and early Bronze Age but some examples have been found to date from the Iron Age.
Some of the carvings have been found on boulders and outcrops overlooking major routes, hunting grounds or water-holes which has led to suggestions they are perhaps used to mark these spots.
Others have suggested they could be a mark of territorial ownership.
Later examples have been found in association with burial or ceremonial sites, suggesting they may have a sacred importance.
