St Columba of Iona, the Apostle of Scotland

Today is the feast  of St Columba or Colum Cille, if you prefer.  He is on the liturgical calendars of Scotland and Ireland but he didn't quite make the cut in the United States.

The Inn had this to say about St Columba a few years ago.  The Catholic Encyclopædia has a detailed life here.  Perhaps the best things on the web on St Columba can be found at the Trias Thaumaturga blog.  You could start here but you don't have to stop there.  A little searching reveals a lot more.
