This podcast takes the concept of 'icons' as its starting point. What are they, how important are they and how do iconic ideas take root? An eclectic array of topics are examined, debated and questioned: how has Hollywood's portrayal of the ancient world influenced our understanding of history? How have theological discussions between Muslims and Christians developed and shaped society? And in what way did ideas of 'liberty' develop in Glasgow, New York and Cork in the early modern age?
