Archbishop Ussher's birthday

Today is Archbishop Ussher's birthday. Born on this day in 1581, he rose to become the archbishop of Armagh and author of The Annals of the World in which he famously dated the dawn of creation on the night preceding October 23, 4004 BC.  As I write, I have deluxe edition of this book (together with a CD -- what would Ussher have made with our technology!) on my desk. It remain a masterpiece of literature. 

My favourite incident from his life is the fact that he watched the execution of Charles I, but fainted just before the axe fell!
 
Any thoughts anyone?
