“In chapter xi., which is entirely devoted to the wonderful achievements of the ancients, we propose to demonstrate our assertions more fully. We will show, on the evidence of the most trustworthy classics, that at a period far anterior to the siege of Troy, the learned priests of the sanctuaries were thoroughly acquainted with electricity and even lightning-conductors. We will not add but a few more words before closing the subject.
The theurgist so well understood the minutest properties of magnetism, that, without possessing the lost key to their arcana, but depending wholly upon what was known in their modern days of electro-magnetism, Schweigger and Ennemoser have been able to trace the identity of the “twin brothers”, the Dioskuri, with the polarity of electricity and magnetism.
Symbolical myths, previously supposed to be meaningless fictions, are now found to be “the cleverest and at the same time most profound expressions of a strictly scientifically defined truth of nature’, according to Ennemoser.”
