Isabel de Clare, daughter and sole heiress of Richard Fitzgilbert de Clare, Earl of Pembroke, also inherited the province of Leinster through her grandfather Dermot McMurrough.

"The Damsel of Striquil" as she was known, was held as a ward of the Crown in the Tower of London from the tender age of four, where her person and her considerable estates were jealously guarded.

In 1189 Henry II gave her in marriage to his heroic and highly talented knight and champion, William Marshal, who, despite his indispensable presence at the side of the Plantagenet Kings for many years, had little material possessions. In 1200.William finally achieved permission from the distrustful King John, to set sail for Ireland with his wife and children, two of his sons being held hostage in England by John. During the voyage, a violent storm erupted in the Irish Sea, threatening to overwhelm the Marshals ship and the accompanying flotilla carrying horses, servants and supplies.

In the panel, William is seen comforting a daughter and standing in the eye of the storm vowing that were they spared, he would build a Cistercian abbey where the ship made landfall. And so it came to pass. Tintern (Minor - to distinguish it from the earlier abbey in Wales) came to be built in Saltmills, south Wexford, in a sylvan setting, by a small stream .

The upper border shows William receiving from the dying King Henry II, his gift of the de Clare bride, his galloping in all haste through Anjou, Maine and Normandy to reach London and presenting himself to his eighteen year old spouse to be.

The lower border shows William protecting the ageing King and running counter to Richard, his son on the battlefield in France. On either side, the forces of the King of France fight against those of the Angevins and vice versa. The yellow broom against the lily.
