One of the earliest legends that connects the Tower with a raven is the tale of the euhemerised mutually destructive battle against the Irish king Matholwch who had mistreated the British princess Branwen.
One legend attributes the start of the tradition of keeping ravens with clipped wings in the Tower of London to Charles II and to his royal astronomer John Flamsteed, although there are versions of the legend that differ in their details [REF].
