a stream, you see, so the real issue was whether the impurity climbed back up that stream and infected the storage jar too. The Pharisees and other Jewish sects took a relaxed view, but the Essenes believed that everything would be contaminated, so they couldn’t risk pouring out contents in a stream. Instead, they’d lift the lid a little, dip in a measuring cup and transfer it that way. And because they no longer had to tip their storage jars, they could have flat bottoms, which made them much more stable; and short necks and fat mouths, too, to make them easier to dip into.’
‘And jars with fat mouths need bowls for lids,’ grinned Omar.
‘Exactly,’ nodded Knox. They were nearing the Desert Road Junction. He hunkered down in his seat to scan the road-signs. A quick review of the records in Omar’s office had shown just four foreign-run sites in the vicinity of Lake Mariut, but there was nothing currently happening at Philoxinite, Taposiris Magna or Abu Mina; which left only one worthwhile candidate: a group called the Texas Society of Biblical Archaeology excavating out near Borg el-Arab.
‘So what would the lid be doing here?’ asked Omar, once Knox had navigated them onto the right road.
‘It may well have come centuries ago,’ shrugged Knox. ‘The Dead Sea Scrolls were known about in antiquity. We have reports from the second, third and fourth centuries of texts being found in Qumran caves. Origen even used them to write his Hexapla .’
‘His what?’
‘The Bible written out six times in parallel columns. The first in Hebrew, the second in Greek, and then a series of edited versions. It helped other scholars compare and contrast the various versions. But the point is, he relied heavily on Dead Sea Scrolls.’
‘And you think they might have been brought here in this jar of yours?’
‘It’s got to be a possibility.’
Omar swallowed audibly. ‘You don’t think we might actually find … scrolls , do you?’
Knox laughed. ‘Don’t get your hopes up. One of the scrolls was inscribed on copper – a treasure map, would you believe? But all the rest were on parchment or papyrus. Alexandria’s climate would have chewed those up centuries ago. Besides, there’s another explanation. A more intriguing one. To me, at least.’
‘Go on.’
‘We’re pretty sure the Essenes didn’t live only in Qumran,’ said Knox. ‘Josephus mentions an Essene Gate in Jerusalem, for example, and several scrolls laid down rules for how Essenes should live outside Qumran. Besides, we know there were several thousand Essenes, whereas Qumran could only hold a few hundred. So obviously there were other communities.’
‘You mean here? In Alexandria?’
Knox grinned. ‘Have you ever heard of the Therapeutae?’ he asked.

The Reverend Ernest Peterson surreptitiously dabbed his brow. He didn’t like being seen to sweat. He didn’t like showing any sign of weakness. Fifty-two years old, ramrod straight, grizzled hair, fierce eyes, a hawk’s nose. Never without his copy of the King James Version. Never without his preacher’s livery. A man proud to show through his own unyielding purpose a faint glimmer of the irresistible strength of God. Yet the sweat kept coming. It wasn’t just the humidity in this cramped, dark underground labyrinth. It was the vertiginous sense of what he was on the verge of achieving.
Thirty-odd years before, Peterson had been a punk – a petty thief, always in trouble with the law. Under arrest one night, dozing on a police bench, glancing up at a Heinrich Hofmann print of Christ hanging high up on the wall, his heart suddenly starting to race crazily, like the most violent panic attack, but which suddenly dissolved into the most intense and serene vision of his life, a blinding white light, an epiphany. He’d stumbled from the bench after it was done, searching for a reflective surface in which to see what imprint it had left upon him: bleached hair, charred skin, albino
