News, London: Egyptian Philae obelisk revealed anew

Fresh information is being obtained on the Philae obelisk, the stone monument that played such a key role in helping to decipher Egyptian hieroglyphs.

Today, the pink granite shaft stands on the UK National Trust's Kingston Lacy estate in Dorset, where it was brought from the Nile in the 1820s.

The obelisk's inscriptions, with those on the famous Rosetta stone, contained clues to interpret the ancient symbols.

Now, the monument is being studied anew with modern imaging techniques.

Oxford University researchers say their investigations are revealing markings that were previously too worn to be investigated properly.

"The last time anyone made a good record of what was on this stone was in 1821 when a lithograph was commissioned to celebrate the obelisk's arrival at Kingston Lacy," explained Dr Jane Masséglia from the Centre for the Study of Ancient Documents.

"We had no way of knowing that that drawing was correct. But our images show that whoever did the lithograph, especially of the hieroglyphs, made a really great job.

"The other big thing for us is the Greek inscription. Even when the obelisk first came to Kingston Lacy, people looked at it and said they couldn't make out the whole thing; there were large sections that were rubbed away.

"But we can now see the remains of that in a way no-one has been able to do previously," she told BBC News.

The obelisk was used with the Rosetta stone to

The toppled 2nd-Century BC obelisk was observed on the Nile island of Philae by adventurer and collector William John Bankes on one of his grand tours.

The obelisk carries Greek inscriptions at its base and hieroglyphs up the length of its pointed shaft.

It is the repetition of the names of ancient Egyptian kings and queens - Ptolemy and Cleopatra - in both writing forms that gave scholars important leads in their quest to translate the older of the two symbolic systems.

But part of the Greek text was always difficult to discern, and the obelisk's exposure to the British climate over the past 200 years has only made that task more difficult.

The Oxford remedy is Reflectance Transformation Imaging (RTI). This involves photographing a stone surface as it is lit from many different angles.

Although the shadows in any one picture will accentuate the relief, it is by combining the whole imaging series that the full topography becomes apparent, especially when colour and specular effects are carefully controlled. Using RTI and other scanning methods on the obelisk has literally shone a light on those previously illegible sections.

"It gives us a good opportunity now to look at the relationship between the two inscriptions, to see if they're talking about the kings in similar ways - because there's the potential that they were appealing to different ethnic communities," said Dr Rachel Mairs, who is affiliated to both Oxford and Reading universities.

"You've got the hieroglyphs that are showing the king as a traditional pharaoh, and the Greek that might be saying something a little bit different to other people reading those inscriptions."
