:''For the mushroom, see'' Mycena aetites'' or'' Mycena ''for the genus.'' In the magico-medical tradition of Europe and the Near East, the aetites (singular in Latin) or aetite (anglicized) is a stone used to promote childbirth. It is also called an eagle-stone,〔The eagle-stone is defined as "the common name of the aetite" by Thomas Wright, ''Dictionary of Obsolete and Provincial English'' (London, 1886), p. 414 (online. )〕 aquiline, or aquilaeus. The stone is said to prevent spontaneous abortion and premature delivery, while shortening labor and parturition for a full-term birth.〔Sarah Iles Johnston, ''Restless Dead: Encounters Between the Living and the Dead in Ancient Greece'' (University of California Press, 1999), p. 167 (online. )〕 From Theophrastus onwards, the belief is also recorded that the stone had the ability to "give birth" to other stones, based on the crystals found within. This fed into the belief that at least some minerals could be gendered into male and female forms.〔Harris, 47-48〕 ==Mineralogy== The aetites is a type of hollow geode; inside, small loose pieces rattle when shaken.〔Jacqueline Marie Musacchio, ''The Art and Ritual of Childbirth in Renaissance Italy'' (Yale University Press, 1999), p. 140 (online. )〕 An official publication of the United States Bureau of Mines in 1920 defined an aetite as: The American Geological Institute defines the eaglestone as "a concretionary nodule of clay ironstone about the size of a walnut that the ancients believed an eagle takes to her nest to facilitate egg-laying."〔American Geological Institute, ''Dictionary of Mining, Mineral, and Related Terms'' (Birkhäuser, 1992, 2nd ed. 2003), p. 179 (online. )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aetites」の詳細全文を読む スポンサード リンク
