well, as a fellow who got his dissertation written on Roman 
Household religion and then moved into American historical 
Archaeology I must say that I agree basically with geoff. I 
had lots of documents to corroborate my archaeological 
shrines at pompeii.I have lots with my Philadelphia sites. 
We have the writing on the walls at Pompeii but we cant 
recover that from the huts of Valley Forge (Could have been 
there..)

But as Joseph campbell says, follow your bliss, and you may 
find that its not what you call what you say but what you 
say itself! vos plaudite et valete...dgo
