Before the throne was something like a sea of glass, similar to crystal. In the midst of the throne, and around the throne were four living creatures full of eyes before and behind.
Daniel 7:7
7
After this I saw in the night visions, and, behold, a fourth animal, awesome and powerful, and strong exceedingly; and it had great iron teeth; it devoured and broke in pieces, and stamped the residue with its feet: and it was diverse from all the animals that were before it; and it had ten horns.
