Caspian's whereabouts circa 0--6CE

[fides]

Does anyone know of any fics where Caspian/Caspari was going by the name Caspar around the time of the birth of Jesus? I was watching QI the other day and the names suddenly struck me since the question was about not actually knowing how many magi there were but one of them was called Caspar.

Caspar -> Caspian/Caspari + rather nasty massacre = bad, bad thoughts

(Historical accuracy be blowed for the sake of 'humour')
