I think you're right about my misinterpretation of the fate of Set; so I concede: you are right!
By the way, do you know the story of Typhous (I think that's how you spell it)? Anyway, in Greek mythology he was a TITANIC son of Mother Earth who tried to overthrow Father Zeus and the other gods. At first they ran away but Zeus overcame him with his thunder and lightning bolts, and threw him into Mt. Aetna, now a volcano, where he is to this day. The greeks always tried to identify their gods with everyone else's, so they ID'd Set with Typhonous, also apparently assoc. with winds (whence Typhoon), like Set is in Egypt, am I right?--a desert storm god?
