Sorry I don't watch the history channel but do know a bit about Nostradamus. There was a full length feature film made in the early 1980's with Orson Welles as the narrator.
Nostradamus was supposed to have been able to see the future. To avoid being persecuted as heretic he wrote his 'visions' in code, in four line poems called quatrains, using a mixture of ancient languages.
His quatrains were translated into a book in the late 20th century. The problem was that because his visions were so heavily coded they could be interpreted in many ways. There are sceptics who doubt the validity of Nostradamus. He supposedly foresaw three anti-christs....Napoleon Bonaparte, Hitler...and a third who would succeed in the year 1999, would wear a blue turban and come from the east.......looks like he missed the bus.
Reasonably interesting stuff but in my view a load of hokus pokus.
