=Three Closures= (_The_) of the island of Britain: (1) The head of Vran, son of Llyr, surnamed “The Blessed,” which was buried under the White Tower of London, and so long as it remained there, no invader would enter the island. (2) The bones of Vortimer, surnamed “The Blessed,” buried in the chief harbor of the island; so long as they remained there, no hostile ship would approach the coast. (3) The dragons buried by Lludd, son of Beli, in the city of Pharaon, in the Snowdon rocks. (See THREE FATAL DISCLOSURES.)--_Welsh Triads_, liii. =Three Counselling Knights= (_The_) of the court of King Arthur: (1) Kynon or Cynon, son of Clydno Eiddin; (2) Aron, son of Kynfarch ab Meirchion Gul; (3) Llywarch Hên, son of Elidir Lydanwyn. So long as Arthur followed the advice of these three, his success was invariable, but when he neglected to follow their counsel, his defeat was sure.--_Welsh Triads._ =Three Diademed Chiefs= (_The_) of the island of Britain: (1) Kai, son of Kyner, the steward of King Arthur. He could transform himself into any shape he pleased. Always ready to fight, and always worsted. Half knight and half buffoon. (2) Trystan mab Tallwch, one of Arthur’s three heralds, and one whom nothing could divert from his purpose; he is generally called Sir Tristram. (3) Gwevyl mab Gwestad, the melancholy. “When sad, he would let one of his lips drop below his waist, while the other turned up like a cap upon his head.”--_The Mabinogion_, 227. =Three Disloyal Tribes= (_The_) of the island of Britain: (1) The tribe of Goronwy Pebyr, which refused to stand substitute for their lord, Llew Llaw Gyffes, when a poisoned dart was shot at him by Llech Goronwy; (2) the tribe of Gwrgi, which deserted their lord in Caer Greu, when he met Eda Glinmawr in battle (both were slain); (3) the tribe of Alan Vyrgan, which slunk away from their lord on his journey to Camlan, where he was slain.--_Welsh Triads_, xxxv. =Three Estates of the Realm=: the nobility, the clergy, and the commonalty. N.B.--The sovereign is not one of the three estates. =Three Fatal Disclosures= (_The_) of the island of Britain: (1) That of the buried head of Vran “The Blessed,” by King Arthur, because he refused to hold the sovereignty of the land except by his own strength; (2) that of the bones of Vortimer by Vortigern, out of love for Ronwen (_Rowena_), daughter of Hengist, the Saxon; (3) that of the dragons in Snowdon by Vortigern, in revenge of the Cymryan displeasure against him; having this done, he invited over the Saxons in his defence.
