Clach an Tuirc

[Famed] for her prophetic gifts was the Lady of Lawers (Bantighearna Lathuir), one of the Breadalbane family, married to Campbell of Lawers. Her prophecies relate to the house and lands of Breadalbane, and are written, it is believed, in a book shaped like a barrel, and secured with twelve iron hoops or clasps in the charter room of Taymouth Castle. This book is called 'The Red Book of Balloch'.
