On a d\u00e9couvert en 1967 au nord de Dublin un site n\u00e9olithique; le tumulus de Newgrange, que l’UNESCO a inscrit au patrimoine mondial. C’est une structure circulaire avec au centre une crypte mortuaire \u00e0 laquelle on acc\u00e8de par un long couloir.<\/p>\n

Le tumulus mesure 15 m\u00e8tres de hauteur et 90 m\u00e8tres de diam\u00e8tre. Il aura fallu environ 200 000 tonnes de pierre et de terre pour le construire il y de cela environ 5000 ans.<\/p>\n

Les constructeurs ont calcul\u00e9 et pratiqu\u00e9 une ouverture parfaitement align\u00e9e de sorte qu\u2019au lever du soleil lors du solstice d\u2019hiver, la lumi\u00e8re p\u00e9n\u00e8tre sur toute la longueur de la crypte, \u00e9clairant celle-ci pendant 17 minutes avant de dispara\u00eetre pour laisser place de nouveau \u00e0 la noirceur. C\u2019est un ph\u00e9nom\u00e8ne qui attire de nombreux touristes.<\/p>\n

Lors de la d\u00e9couverte du tombeau, les arch\u00e9ologues furent stup\u00e9faits qu\u2019une si ancienne construction en pierre d\u00e9montre que les gens de cette \u00e9poque aient eu une telle ma\u00eetrise de l\u2019architecture et une connaissance si pr\u00e9cise du mouvement du soleil.<\/p>\n

Pourtant les exemples d\u2019anciennes constructions qui t\u00e9moignent d\u2019excellentes connaissances scientifiques et architecturales ne manquent pas. On n\u2019a qu\u2019\u00e0 penser aux temples \u00e9gyptiens parfaitement orient\u00e9s, \u00e0 la grande pyramide de Chichen Itza, aux cath\u00e9drales gothiques, etc.<\/p>\n

De telles \u0153uvres myst\u00e9rieuses, on en retrouve sur tous les continents. Il est certes fort int\u00e9ressant d\u2019appr\u00e9cier les connaissances scientifiques des anciens et leur ma\u00eetrise de la construction en pierre et autres mat\u00e9riaux.<\/p>\n

Mais il est encore plus pr\u00e9cieux de chercher \u00e0 comprendre \u00e0 la fois l’utilit\u00e9 pratique et le sens plus profond, m\u00e9taphysique et symbolique, qui justifiait de r\u00e9aliser de telles \u0153uvres.<\/p>\n
