Et similitudo super capita animalium firmamenti, quasi aspectus crystalli horribilis, et extenti super capita eorum desuper.
And over the heads of the living creatures was the likeness of the firmament, the appearance of crystal terrible to behold, and stretched out over their heads above.
Et similitudine super capites de animales de firmamento, quasi aspectu de crystallo horribili, et extenta super capites de illos desuper.
