crânes de cristal 2

Je voulais donner quelque précisions sur le message précédent :

la thermoluminescence ne donnerait sûrement pas grand chose. De toute façon, cela ne daterait que la matière, il y aurait pu avoir façonnage après.

Cela n'empêche pas certains sites de dater le "crâne" de 3600 AJC.

Bon, quant à cette fameuse légende elle est apparue par génération spontanée avec le crâne !

Ajoutons qu'aucun autre des soi-disant 13 autres crânes n'a les soi-disant même caractéristiques. voir le lien ci-dessous.

Par  ailleurs, j'ai oublié quelque chose, qui m'est venu, mais je ne sais plus quoi.

Oui, c'est que, accessoirement le polissage peut venir de l'eau seule ou bien aussi de multiples caresses humaines.

 Du nouveau très très intéressant sur les crânes de cristal !

Rock crystal skull

Probably European, 19th century AD

Large quartz crystal skulls have generated great interest and fascination since they began to surface in public and private collections, during the second half of the nineteenth century. Some of them have been attributed to the work of Aztec, Mixtec or even Maya stone workers. Others are said to be examples of colonial Mexican art, for use in churches, perhaps as bases for crucifixes.

The Department of Scientific Research at the British Museum has concluded that the quartz crystal used in the manufacture of this example is likely to have come from Brazil. Moreover, it bears traces of the use of a jeweller's wheel, which was unknown in the Americas before the arrival of the Europeans. These traces and the high polish of its surface indicate that it was carved using traditional European techniques.

The crystal skull was said to have come from Mexico, brought to Europe by a Spanish officer, before the French occupation. Sold to an English collector, upon his death it was acquired by Eugène Boban, a French antiquities dealer. It became the property of Tiffany and Co., N.Y., from whom it was purchased for The British Museum. Boban could have acquired the skull in Germany, where large quantities of Brazilian quartz crystal were shipped in the early nineteenth century.
