Jewish Lightning Rod: Between Magic and Science
Lechaim, September (2008), pp. 39-43
Apparently, it is these ideas about stones which can defer thunderstorm, protect against hail and rescue from lightning in a magical way, which were popular in the Muslim East during the Middle Ages, that arrived to western boundaries of the populated universe. Rabenu Bahye, a student of Spanish rabbis, also knew about them. Therefore, as in his opinion the properties of stones could not have changed since the Confusion of tongues, he provided information which he considered to be obtained from experience and trustworthy, as a confirmation of his views on the purpose of the Babel Tower.
