In the Bartimaeus trilogy, the main character is the eponymous djinni Bartimaeus, a demon/spirit from "the Other Place" who is cheeky, witty, boastful, and at times surprisingly deep.
Bartimaeus, however, is also the name of a man in the New Testament of the Bible. What's the connection there? Does the name in Jonathan Stroud's novels come from this Biblical Bartimaeus, or from somewhere else? Why?
