What do the six petals mean?
I have read a number of interpretations of the six petals. In fact, the geometry of the center of the labyrinth is based on seven, not six. The seventh is the center circle. The number seven has very unique properties. Within the first ten numbers, one through ten, seven is the only number that neither generates nor is generated by another number. For that reason, it has always been known as “the virgin.” In a cathedral dedicated to the Virgin Mary, this makes sense.
