ナイル川の遺跡調査

ナイル川の本格的な水中考古学サーヴェイが行われるそうです。アレキサンドリア水中遺跡の調査団長とエジプト考古学の権威ザヒ・ハワス先生が指揮を取るようです。アスワンとアバイドス間を主に調査するようです。GPS連動のサイドスキャンソナーを使って調査をします。

海水と違い淡水は保存状況が良いのと、ナイルの泥が遺物を保護している可能性があり、大型の船やオベリスクを運んだ船などが発見されることが期待されます。

Alaa Mahrous, director of the underwater antiquities department in Alexandria, said that the archaeological team headed by Dr Zahi Hawass, director of the Supreme Council of Antiquities, has selected the Nile to be the subject of their search, as the river has not been excavated till date.

“The survey will cover the area between the quarries in Aswan and Abydos. Over the centuries this was a significant area – either for the ancient Egyptians or the many rulers of the country who followed. The granite quarries were located in Aswan. The statues and obelisks used to be cut and shaped in the mountains before they were shipped to Luxor and Abydos,” said Mahrous.

Mahrous said the team was hoping to find any such pieces that might have sunk while being loaded on unloaded from ships.

“It is also possible to discover shipwrecks as many huge boats sank along with their load which consisted of statues, pottery and merchandise. We also have information regarding two small obelisks that settled in the river bed 10 km off Luxor as they were being shipped to Cairo by Maspero,” said Mahrous.

He said fortunately though, the geography of the Nile hadn’t changed, especially in Upper Egypt.

In addition, the river’s alluvial mud acted as a protective agent, unlike the seawater that eroded the wood, he said.

He said a state-of-the-art technology would be used in the survey, which will include a sizeable rubber boat that has been provided with special facilities for accommodating and protecting the survey tools.

“Our survey tools will consist of the ‘side scan sonar’ that reveals the artefacts buried under the river bed, the ‘Bommer’ that penetrates the mud and sand found in the depths of the river as well as the GPS that is used in pointing out geographical locations, a tool that will prove effective in spotting the artefacts’ exact locations,” he said.

“We will be able to read the results immediately, because the sonar is also connected to a computer on board, which will show images of what stands on the river bed or what is buried under the mud. The GPS will guide us through several geographical locations.

“In the case of an object being discovered, our team of divers will swim down to examine it, ensuring it isn’t a significant monument that would be missed. But a small dive as this isn’t as easy as some might think. To dive in the Nile you also have to deal with strong winds, the high density of the river water and intensity of alluvial mud that, within seconds, can turn the surroundings into dark recesses,” he added.

He said, based on the information relating to this survey, the ensuing stages will be decided.

“I would like to stress again that this will be only a survey to locate the site of the antiquities. Recovering them will follow at a different stage. We aim to carry out a survey of all the locations of sunken antiquities countrywide, a plan that will take us years of hard work,” the Daily News Egypt quoted Mahrous, as saying.
