In the first years of the twelfth century a pious hermit named Lyger took up his abode in these solitary regions, built a dwelling for himself, and settled down to spend his life in doing good works and in the practice of religion. Soon, as others gathered round him, his dwelling grew into a monastery, and at last, in the year 1122, the Abbey of the Dunes was founded. It was nearly half a century before the great building, which is said to have been the first structure of such a size built of brick in Flanders, was completed; but when at last the work was done the Abbey was, by all accounts, one of the most magnificent religious houses in Flanders, consisting of a group of buildings with no less than 105 windows, a rich and splendid church, so famous for its ornamental woodwork that the carvings of the stalls were reproduced in the distant Abbey of Melrose in Scotland, and a library which, as time went on, became a storehouse of precious manuscripts and hundreds of those wonderfully illustrated missals on which the monks of the Middle Ages spent so many laborious hours. We can imagine them in the cells of Coxyde copying and copying for hours together, or bending over the exquisitely coloured drawings which are still preserved in the museums of Flanders. But their most useful work was done on the lands which lay round the Abbey. There were at Coxyde in the thirteenth century no fewer than 150 monks and 248 converts engaged at one time in cultivating the soil.[27] They drained the marshes, and planted seeds where seeds would grow, until, after years of hard labour on the barren ground, the Abbey of the Dunes was surrounded by wide fields which had been reclaimed and turned into a fertile oasis in the midst of that savage and inhospitable desert.
