Mise sous le feu des projecteurs par le c\u00e9l\u00e8bre Da Vinci Code<\/strong>,\u00a0Saint-Sulpice attire de plus en plus de monde depuis quelques ann\u00e9es. Mais contrairement \u00e0 ce que la fiction indique, le vrai secret de ce monument de Saint-Germain-des-pr\u00e9s<\/strong><\/a> n’est pas une cl\u00e9 de vo\u00fbte myst\u00e9rieuse\u00a0mais un instrument de mesure insolite…<\/b><\/p>\n

Nich\u00e9 dans le transept nord, il s’agit d’un\u00a0gnomon <\/strong>du 18\u00e8me\u00a0si\u00e8cle. Ce\u00a0mot grec signifie \u201cmoyen de savoir\u201d,\u00a0et il d\u00e9signe un\u00a0outil permettant de d\u00e9terminer la date pr\u00e9cise de P\u00e2ques <\/strong>en fonction du soleil. Install\u00e9 \u00e0 Saint-Sulpice en 1727,<\/strong>\u00a0il a la forme d’un ob\u00e9lisque et intrigue toujours les visiteurs !<\/p>\n

Mais alors, comment fonctionne t-il ? Au pied de ce magnifique instrument en marbre blanc<\/strong> de 10,72\u00a0m\u00e8tres de hauteur, la\u00a0m\u00e9ridienne de Paris<\/strong>\u00a0a \u00e9t\u00e9 mat\u00e9rialis\u00e9e par\u00a0une r\u00e9glette de laiton\u00a0incrust\u00e9e dans le dallage de l’\u00e9glise. Dans le vitrail d’en face en haut du transept sud,\u00a0une lentille<\/strong>\u00a0est \u00e9galement plac\u00e9e \u00e0 une 24,54\u00a0m\u00e8tres de hauteur. A des moments tr\u00e8s pr\u00e9cis de l’ann\u00e9e, les\u00a0rayons du soleil passent\u00a0par la lentille et viennent frapper l’ob\u00e9lisque ou la ligne de laiton\u00a0au sol, indiquant\u00a0les\u00a0solstices d’\u00e9t\u00e9 et d’hiver<\/strong> ainsi que les \u00e9quinoxes de mars et de septembre<\/strong>\u00a0(qui marquent le d\u00e9but du\u00a0printemps\u00a0et de\u00a0l\u2019automne).<\/p>\n
