AIDAN, or SEDAN, first bishop of Lindisfarne, a monk of Hii (Iona), was sent by the abbot Senegi to Northumbria, at the request of King Oswald, A.D.
He survived Oswald, and died shortly after the murder of his friend Oswine of Deira, on the 31st of August 651, in the 17th year of his episcopate.
During the reign of Oswald Penda clearly reigned under the suzerainty of that king.
In 642, however, Oswald was slain by Penda in a battle at a place called Maserfeld, which has not been identified with certainty.
The Miocene period is unrepresented by any deposits in Great Britain, unless the Bovey lignite should belong to its earliest stage; we will therefore commence with the best known region - that of central Europe and especially of Switzerland, whence a prolific flora has been collected and described by Oswald Heer.
