There are 62 musician angels encircling Christ (at center) in this rose. This window is designed symmetrically, having matching angels and instruments, a pair, one left and one right of center in the same spots. The bass viol is at dead-centered just below Christ. The two arm viols are mid-way above Christ at left and right center, forming a perfect equal-lateral triangle with the bass viol.
