Lumen, I've not done the puzzle, but from the mentions on here, I think it's Arab, this person, from Scarab, a symbol of their ancient ancestors (with the 'sc', abbreviation listed in Chambers, dropped).
Thanks malone.
I was sure it had to be a name, so went with Alan, which was a bit lame!
This clue excepted, a great puzzle, hope you have time to try it.
