BigTimedWarfer, what was Sarah's interpretation for what Coifi did? I'm trying to remember who first clued me into that interpretation of the spear... It might have been Kirby, Carver, or Stenton... but it also could have been Blair... I really can't remember. But I remember reading it and thinking "that's a fascinating notion!"
I'll quote rather than paraphrase. In a passage discussing the appearance (layout) of pagan religious sites she says, "a senior pagan priest Coifi, attacks his heathen temple as a way of breaking with paganism. Coifi sets out on a stallion bearing a spear (pagan priests were only permitted to ride a mare and go unarmed) and rides up to where the idols are lodged, then casts his spear into the temple to profane it and instructs his companions 'to set fire to the temple and its enclosures and destroy them'."It's on page 45 of my edition.
