Dives & Lazarus:
In Jesus' parable about the rich man and the poor man who sits at his gate [Luke 16:19-31], the poor man is named (Lazarus), but the rich man is not.
Recently, people have taken to calling the rich man Dives, which is the latin word for rich.
However, he has previously been called: Nineves; Neves; Finaeus; Tantalus; or Amonofis.
There is accordingly no reason why you can't make up your own name for him.
