An Aetites may be defined as any hollow stone containing loose matter, a smaller stone or sand, which rattles when shaken. Such objects are of little interest to the modern geologist, who usually breaks them open in order to examine the interior for crystals or impressions of fossils. Their importance to the archaeologist and student of folk-lore may be gauged by the fact that they are mentioned by Dioscorides about A.D. 69 and in the fourteenth edition of Quincey's Pharmacopoeia, published in 1769. A series of at least a hundred references between these dates could be compiled ; only those necessary to elucidate the history of the Eagle-stone need be given.
