File talk:Altamira Ocre MHNT.PRE.2012.0.610.jpg

About the mill:

I can't find anything about this rock, or any similar rock, in Breuil & Obermaier (1935). Neither there is anything in Breves apuntes de Sautuola (1880).

I am looking for it in other publications and papers.

Now you can find Breves apuntes in Wikisource (Breves apuntes) --Nachosan (talk) 00:14, 8 February 2013 (UTC)[reply]

Sautuola in his work Breves apuntes (page 21) mentione the presence of hematite (red ocre) and he associeted them with the pictures. In the same document (pages 12 and 14) talked about rolling stones but he didn't say anything about the possible use of them how mill.

I have found that in the cave of Tito Bustillo have been found «..., placas grabadas, colorante, "lapices" y trituradores de ocre, etc. [..., engraved plates, "pencils" and mills of ocre, etc.]» according to Moure Romanillo.

A question, do you have access to the publications of Cartailhac and Breuil?, specially to La Caverne d'Altamira à Santillane près Santander. 1er volumen de la serie Peintures et gravures murales des cavernes paléolithiques. Thank you in advance. --Nachosan (talk) 21:23, 10 February 2013 (UTC)[reply]
