When St. Bernard was preaching the Crusade in Flanders he came to Coxyde. On his advice the monks adopted the Order of the Cistercians, and their first abbot under the new rule afterwards sat in the chair of St. Bernard himself as Abbot of Clairvaux. Thereafter the Cistercian Abbey of the Dunes grew in fame, especially under the rule of St. Idesbaldus, who had come there from Furnes, where he had been a Canon of the Church of Ste. Walburge. 'It has also a special interest for English folk. It long held lands in the isle of Sheppey, as well as the advowson of the church of Eastchurch, in the same island. These were bestowed on it by Richard the Lion-Hearted. The legend says that these gifts were made to reward its sixth abbot, Elias, for the help he gave in releasing Richard from captivity. Anyhow, Royal charters, and dues from the Archbishop of Canterbury, and a Bull of Pope Celestine III., confirmed the Abbey in its English possessions and privileges. The Abbey seems to have derived little benefit from these, and finally, by decision of a general congregation of the Cistercian Order, handed them over to the Abbot and Chapter of Bexley, to recoup the latter for the cost of entertaining monks of the Order going abroad, or returning from the Continent, on business of the Order.'[*] [Footnote *: Robinson, _Bruges, an Historical Sketch_, p. 176.] [Illustration: COXYDE. A Shrimper.] The English invasion of the fifteenth century destroyed the work of the monks in their fields and gardens, but the Abbey itself was spared; and the great disaster did not come until a century later, when the image-breakers, who had begun their work amongst the Gothic arches of Antwerp, spread over West Flanders, and descended upon Coxyde. The Abbey was attacked, and the monks fled to Bruges, carrying with them many of their treasures, which are still to be seen in the collection on the Quai de la Poterie, beyond the bridge which is called the Pont des Dunes. The noble building, so long the home of so much piety and learning, and from which so many generations of apostles had gone forth to toil in the fields and minister to the poor, was abandoned, and allowed to fall into ruins, until at last it gradually sunk into complete decay, and was buried beneath the sands. Not a trace of it now remains. History has few more piteous sermons to preach on the vanity of all the works of men.
