"The boats are like the servants who were buried at Abydos," says O'Connor. "The king intended to use t hem in the afterlife in the same manner that he used them before his death." In life the boats enabled the king to travel rapidly up and down the Nile in a powerful display of wealth and military might. As the Egyptian kings also expected to be kings in the afterlife, the boats would be useful tools.
News of the boats'discovery rippled through the Egyptology world and also energized O'Connor's hunt for the lost enclosures of the first kings. To help focus the search, O'Connor and Adams sought out Tomasz Herbich, a Polish archaeologist who specializes in finding buried ruins with a device called a fluxgate gradiometer, a type of magnetometer. It measures slight variations in the Earth's magnetic field caused by certain types of iron oxides beneath the surface. "These oxides are present in Nile mud," explains Herbich. "And what's the main material used by ancient Egyptian builders? Sun-dried bricks made of Nile mud!"
For nearly a week in 2001 Herbich's assistant walked more than ten miles (16 kilometers) a day over a numbing grid, taking over 80,000 measurements. The survey turned up several small funerary chapels but no enclosures. Then, during Herbich's last hour in the field, his magnetic divining rod finally found royal mud. He downloaded the data onto his laptop, and as the digital map came into focus, he called out, "We have an enclosure!"
Adams and a small crew went to work uncovering part of the enclosure, but the field season was ending, and they had to rebury it and return home. In 2002 O'Connor again asked Adams to go to Abydos, this time to undertake a massive excavation of the new discovery.
After a month of tediously peeling back layers of sand, Adams uncovered jars and wine stoppers bearing Aha's name, confirming that his lost funerary enclosure was at last found.
Once the crew reached the enclosure's floor, they discovered six surrounding graves. Three contained the bodies of adult women, one held the remains of a man, and one held a young child with 25 ivory bracelets embellished with tiny lapis beads. The sixth grave remains unexcavated. In each case the archaeological evidence pointed to a sacrificial death.
"The graves were dug and lined with bricks, then roofed with wood and capped with mud-brick masonry," says Adams. "Above that masonry cap, a plaster floor extends out from the enclosure and covers all the graves." The floor extension is seamless-an important clue, for it would have been impossible to entomb people under the floor except all at the same time.
It's unlikely that 41 people-the six at Aha's enclosure plus 35 at his tomb-would have died of natural causes at the same time. Another possibility is that they died randomly over time and were then stockpiled and reburied en masse. But for O'Connor and Adams, the evidence strongly suggests they were sacrificed.
