The Mysterious Green Flash at Strasbourg Cathedral
by Francois Hagnere on 04/11/09 at 4:50 am
People throng into the Strasbourg cathedral twice a year for an amazing equinoctial light phenomenon.
The green flash is an optical phenomenon taking place just after sunset or before sunrise. It has become a myth and a novel by Jules Verne in 1882. If you happen to see it, you will always be sure about your love feelings. That is for the legend.
Twice a year, for the Spring and Autumn equinoxes, crowds throng into the Strasbourg cathedral. A mysterious light phenomenon appears at 11:38 on March 20, and September 21, it lasts several days. The patriarch Judah, an ancestor of the Christ, is featured in one of the South triforium windows and will be our guide. He looks towards the sun above his right shoulder whilst his index shows his left foot, thus indicating the sun goes through his green foot at a determined moment and from a certain angle. This stained glass window dates back to 1876 and the sun crosses the nave of the cathedral via this beautiful window on every sunny day and particularly on these dates. The green beam reaching the pavement in the Spring creates an oval that moves with the sun, reaches the 15th century pulpit and lights the head of the Virgin, runs along the Christ’s right and left arm, then above his head and finally down to Saint-John’s head. The same phenomenon appears in Autumn, the beam is then white, from another part of the stained glass window, the sun being lower over the horizon.
The show is lovely and attracts many enthusiasts each year. According to the Strasbourg Astronomical Observatory, this occurred accidentally following the restoration of the window in the ’70s. If there is an intention, the tradition was then respected. The Strasbourg green flash symbolically is a tribute to the Sun, to the solar Christian religion. The green color is linked to Nature and Hope and white to Pureness. Various similar phenomena do exist in other sanctuaries in France and other countries. The Strasbourg cathedral is also famous for its astronomical clock.

Very magical. I remember Rouen Cathedral from Earl Horter’s pen drawings where he sketched the front of the church which resembles this one. I suppose the architecture is similar in your country, Francois. BTW I used to be quite an expert in calligraphy when I was young using speedball pens from which I was reminded of the drawing in the brochure/manual. Another nice post my friend, thanks.

Yes, the craftsmanship it must have taken is beautiful and stunning within these elegant pictures. What a beautiful church, but what do you attribute this phenomena ? Is it a divine, ethereal? Very interesting as it happens consistently every year. Very intriguing article Francois.

The phenomenon is fascinating, and even without it, Strasbourg and its cathedral are worth visiting anytime.

Excellent piece and something we might not have known about otherwise. The only occasion I visited France was a trip to Strasbourg, unfortunately I did not get to see the cathedral. Next time I will make it a definite stop off.

Beautiful cathedral. I’ve not heard the story about the light. Strasbourg itself is fascinating, especially the old town.
