You mean Satan, as depicted in Dante's Inferno, yes? Certainly Satan thinks himself the center of the universe!

It seems to me (from summaries that I've read) that the Divine Comedy shows the one "center of the universe" at the bottom of hell to be a false center, the real center being at the peak of heaven, outside of the physical order altogether, in the depths of the Trinity's interrelations.
