Sun light effects in the cathedral of Majorca Authors Daniel Ruiz Aguilera Josep Lluís Pol i Llompart Abstract The article studies the orientation of the cathedral of Majorca related to the light and color effects that the light rays cause with the rose window projections. One such well-known and well-documented effect is produced around February 2nd and November 11th. The rays of the sun pass through the Eastern rose window (also called the Oculus Maior) projecting onto the main doorway and being aligned under and tangent to the Western rose window. The other main effect studied in the article is produced around Christmas: the rays of the sun pass through the Oculus Maior and coincide exactly on the Western rose window. During those days, the Western rose window appears to be lit from inside if viewed from an appropriate point of view outside the cathedral. The fact is that the apse of the cathedral ofMajorca is oriented to the sunrise during the winter solstice, and the authors have not found any documentation on this effect. The article analyzes the possible intentions of this fact from the architectonic and historic point of view.Key words: light effects, cathedral of Majorca, orientation Downloads PDF (Català) Published 2010-10-25 Issue Nova època, vol. 3 (1) : 2010 Section Articles License The intellectual property of articles belongs to the respective authors.On submitting articles for publication to the journal Actes d’Història de la Ciència i de la Tècnica, authors accept the following terms:Authors assign to Societat Catalana d’Història de la Ciència i de la Tècnica (a subsidiary of Institut d’Estudis Catalans) the rights of reproduction, communication to the public and distribution of the articles submitted for publication to Actes d’Història de la Ciència i de la Tècnica.Authors answer to Societat Catalana d’Història de la Ciència i de la Tècnica (SCHCT) for the authorship and originality of submitted articles.Authors are responsible for obtaining permission for the reproduction of all graphic material included in articles.SCHCT declines all liability for the possible infringement of intellectual property rights by authors.The contents published in the journal, unless otherwise stated in the text or in the graphic material, are subject to a Creative Commons Attribution-NonCommercial-NoDerivs (by-nc-nd) 3.0 Spain licence, the complete text of which may be found at http://creativecommons.org/licenses/by-nc-nd/3.0/es/deed.en.
