Every year on the day of Sant Martí (November 11th), one can see an awe-inspiring natural light show inside Palma’s Cathedral. Shortly after 08h00, the morning sun enters through the large stained glass window on the Eastern façade and projects the rose window’s colourful pattern on the opposite interior wall, below the Roseton of the main portal. The Cathedral doors, including the main portal, will open earlier than usual that day, Friday, to allow us to appreciate this beautiful spectacle. Admission is free. Don’t come too late; it will all be come and gone within a mere 35 minutes. If you can’t make it this time, the same effect can be witnessed again on February 2nd, come rain or shine. Well, that is not quite true. The suns reflection can’t be seen if the clouds obscure the sunlight from entering the Cathedral. Let’s hope the weather will be as good on Friday as the forecast predicts.
The Societat Balear de Matemàtiques will organise an event at the Cathedral on Saturday, November 12th, at 08hoo, including a visit into the Cathedral as well as scientific and mathematical explanations of this remarkable event (in Catalan). I believe that event to be free, but, you will have to put your name down if you would like to attend (laseu [at] xeix.org).
