Simon ( the Zealot ) was believed to have preached the Gospel throughout North Africa, from Egypt to Mauritania, and even into Britain.
There is a church tradition which says that he was crucified by the Romans in Caistor, Lincolnshire,
Britain and subsequently buried there on May 10, circa 61 A.D. This cannot be confirmed, however, as there is also a strong tradition which says, that having left Britain, Simon, at some point , went to Persia and was martyred there by being sawn into.
