It could refer to literal King of Tyre in Alexander's day. That civilization was destroyed and passed away and that earthly king who claimed to be god had no more being as an earthly monarch. Then again it could be a blending of both the king and satan following parrallel courses. Satan would have set the pattern and the king followed his footsteps.

They considered the masses of men as only their servants who are here for the purposes of laboring and toiling for their personal benefit. The ancient pharoahs were an excellent example of this condition. The common people practically lived in slavery, toiling to build the pyramids and the great temples. The fruits of the toil of their hands were seized by the government in order that the reigning people might have everything for which they yearned. What was true of the pharoahs was also true of the Assyrians, Babylonians the Hittites and other ancient rulers.
