Dr Ragnhild Ljosland is one of the guests on a BBC Radio 3 broadcast focusing on runes on Sunday evening.

Presented by Dr Eleanor Rosamund Barraclough, a medieval Norse historian, the programme looks at the ancient writing system and asks why were runes so widespread? And what is it about them that so fascinates us today?
The Ancient Algorithm begins at 6.45pm (BST) on Sunday, April 24, 2022, and will be available here, via iPlayer, after broadcast.
