A tale of two Dragons

Following on from the news of Caerffili's reopening, here's A tale of two Dragons

There's a great animatronic display there, recently improved as part of the refurb of Castell Caerffili 

From AI:-

The legend of Dinas Emrys tells of King Vortigern attempting to build a fortress there, but the walls kept collapsing. According to a Welsh legend, he sought the counsel of a boy named Emrys (also known as Merlin Ambrosius or Myrddin Emrys), who revealed the cause: a hidden pool containing two fighting dragons, one white and one red, symbolizing the Saxons and the Britons, respectively. The red dragon, representing the Britons, eventually defeats the white dragon, signifying the Britons' eventual victory over the Saxons. After Vortigern's downfall, the site was given to Ambrosius Aurelianus, from whom the hillfort derives its name.

Who was this Emrys, I hear you ask? well:-

Ambrosius_Aurelianus, or Emrys Wledig:- from wiki:-

Was a war leader of the Romano-British who won an important battle against the Anglo-Saxons in the 5th century, according to Gildas. He also appeared independently in the legends of the Britons, beginning with the 9th-century Historia Brittonum. Eventually, he was transformed by Geoffrey of Monmouth into the uncle of King Arthur, the brother of Arthur's father Uther Pendragon, as a ruler who precedes and predeceases them both. He also appears as a young prophet who meets the tyrant Vortigern; in this guise, he was later transformed into the wizard Merlin.

Gosh! I never knew! So who was Vortigern?:-

Vortigern (/ˈvɔːrtɪdʒɜːrn/ ;Old Welsh: From Wiki:-

Was a 5th-century warlord in Britain, known perhaps as a king of the Britons or at least connoted as such in the writings of Bede and Gildas. His existence is contested by scholars and information about him is obscure.

He may have been the "superbus tyrannus" said to have invited Hengist and Horsa to aid him in fighting the Picts and the Scots, whereupon they revolted, killing his son in the process and forming the Kingdom of Kent. It is said that he took refuge in North Wales, and that his grave was in Dyfed or the Llŷn Peninsula. Gildas later denigrated Vortigern for his misjudgement and also blamed him for the loss of Britain. He is cited at the beginning of the genealogy of the early Kings of Powys.

Coincidentially it's also the name of our favourite bread.
