Description
Summary:A RECENT discussion about reversed geomagnetic events in the Brunhes epoch contains the statement that no archaeological materials are known to be reversely magnetized 1 . This may be true for the specific region that is considered in the article, but it is not true in general. G. Folgheraiter in “Rendi Conti dei Licei”, 1896, 1899; Archives des sciences physiques et naturellas (Geneva), 1899; Journal de physique , 1899; and P. L. Mercanton, in “La methode de Folgheraiter et son role en geophysique”, Archives des sciences physiques et naturellas , 1907, reported observations made on clay fired in kilns by the Etruscans and Greeks. Their results indicate that in the eighth century BC the Earth's magnetic field was reversed.
