This is an amazing video of an eclipse of the sun in the Faeroe Islands, which are in the North Atlantic, halfway between Norway and Iceland. (Yes, I had to Google that) An English friend tells me this is Eclipse Day and many in the UK and Europe will be lucky enough to witness this fascinating phenomenon; how much will depend where you live. http://www.nbcnews.com/news/world/tim...
The only eclipse that I can think of that occurred during the lifetimes of some of your characters is that of 2nd August 1133. It was a total eclipse visible in England and in Germany, and Maud's father, King Henry I had recently departed England for Normandy, so this was interpreted as an omen of his death - which later seemed confirmed by his actual death in Normandy shortly thereafter.
