Solar Eclipse August 2nd 1133
One of the most celebrated eclipses of mediaeval times. The eclipse lasted for over 4 minutes and 38 seconds and maximum was at 12h 08m 38s it was total across a large part of Scotland and parts of North and East Yorkshire.
It was considered as a warning of misfortune to Henry I of England as was recorded by William of Malmesbury. The predictions were correct because Henry I would die on December 1st 1135 while campaigning in France apparently by eating too many lampreys or eels against the advice of his physicians advice.
His death would lead to the English Civil war between his daughter Matilda and his nephew King Stephen.
