Lunar Eclipse and the death of a Pope
On November 30th 1099 there was an eclipse of the Moon visible over Europe. The maximum part of the eclipse began at 16.14 UT (Universal Time) and lasted for 1 hour and 39 minutes.
Somewhat earlier on the year on July 29th Pope Urban II died. He is best remembered for starting the First Crusade an attempt to capture the Holy Lands which had been captured by the Muslims between 632-661. This crusade lasted from 1096-1099.
Urban II died on 29 July 1099, fourteen days after the fall of Jerusalem to the Crusaders, but before news of the event had reached Italy.
