This year All Things Considered marked the 900th anniversary of St David's recognition by Pope Callixtus II as patron saint of Wales, when he declared that two pilgrimages to St Davids were worth one to Jerusalem. Across the seven weeks between St David's Day and Easter this year, All Things Considered and Celebration celebrated the life and impact of this man whose feast day we mark every year but about whom we know relatively little. During the course of the series programmes were made examining David's relationships with Pembrokeshire, Brittany, Rome and Jerusalem – following in the footsteps of the saint himself, and asking what this medieval figure might have to teach us today. Jonathan Thomas introduces highlights from the series.
