Funny how one's mind can dig secret passages from one bit of information to another, isn't it? I've just realized that, for years, I've associated Urien of Rheged (fl. late 6th century AD) with Sargon of Akkad (fl. 23rd century BC). Consequently, whenever I think of Urien (which is, admittedly, not often) I see this image in my mind's eye.
I'm fairly sure that's not what Urien looked like.
Perhaps one day I should spring clean and reorganize my brain in order to iron out these anomalies? I suppose - but I think I'd miss the old place.
