It is estimated to contain the skeletons of between 40,000 and 70,000 people, whose bones were artistically arranged by Frantisek Rint to form chapel decorations in 1870. Maxim Velcovsky pays homage to Rint’s actual bone chandeliers by imprinting their shapes into a glass form. Small parts are made by glass pressing, large parts are hand-blown and the chains created by small “bones” paraphrase the “immortal” classical chandeliers.
