Prince Oldenburgsky and Beelzebub

If this episode has a base in historicel fact, the person Beelzebub/Gurdjieff met in Egypt would have been Prince Alexander Petrovich Oldenburgsky (1844-1932).

In Tales, Beelzebubs function in relation to the Temperance committee is the curing of alcoholics, something for which Gurdjieff had proved adept.
