‘I’m wondering if this could be our Knossos.’

‘This isn’t Mycenaean or Minoan, Professor Gusack; I can assure you of that!’

‘I didn’t mean that,’ replied Gabrielle irritably. ‘I mean another syllable alphabet, like Linear A or Linear B.’

‘And I suppose you were hoping to be the next Michael Ventris.’

‘Well, it would be nice to follow in the footsteps of the man who rewrote ancient Greek history.’

‘Nice, perhaps. Likely, no.’

‘What makes you so sure?’

Mansoor’s voice took on a dour tone. ‘Well, as far as I can tell, there aren’t enough unique characters for a syllable alphabet.’

‘So it’s… what? A phonetic alphabet?’

‘Precisely. More specifically, an abjad. No vowels – just consonants.’

‘Aramaic? Phoenician?’ She didn’t bother to include Hebrew or Arabic in her question, because both were familiar to her and she could tell immediately that it wasn’t either.

‘It doesn’t look all that much like Aramaic. It might bear some vague comparison to Phoenician.’

‘Vague comparison?’ Gabrielle echoed.

‘It’s hard to tell until we can look at them under the right lighting conditions. I’ll get one of the photo experts to take some pictures and play around with the contrast then we’ll take another look.’

‘But what’s your gut instinct?’

Mansoor looked at Gabrielle with mild irritation. She was being pushy. He decided nevertheless to hazard a preliminary speculation.

‘It reminds me of the Serabit el-Khadim inscriptions.’

‘Proto-Sinaitic?’

‘Yes.’

Proto-Sinaitic was one of the oldest phonetic alphabets ever used – if not the oldest – dating back nearly 4,000 years. The name was derived from the Greek ‘proto’ meaning first and the place where the writings in the alphabet were initially discovered: Sinai. Some thirty engravings of the script had been found in Sinai at the turquoise mines at Serabit el-Khadim, once used as a penal colony by ancient Egypt.
