A poem celebrating the actions of a Welsh nobleman has shed new light on the death of Richard III.
The skeleton of the king was uncovered in a Leicester car park, showing distinctive wounds to his skull after his death at the hands of Henry Tudor's men.
The man claimed to have felled the last Plantagenet king at the Battle of Bosworth Field in 1485 was Rhys ap Tomos, who was knighted by the new King Henry VII for his support.
Now, as Gwenfair Griffith reports, Welsh literature is helping support archaeologists trying to pinpoint just how Richard died.
