It was believed in Ypres that the town had been saved by the intercession of the Virgin Mary, its patron saint. In the Cathedral Church of St. Martin the citizens set up an image of Notre, Dame-de-Thuine, that is, Our Lady of the Enclosures, an allusion to the strong barrier of thorns which had kept the enemy at bay; and a kermesse, appointed to be held on the first Sunday of August every year in commemoration of the siege, received the name of the 'Thuindag,' or Day of the Enclosures.[*] The people of Ypres, though they fought on the French side, had good reason to be proud of the way in which they defended their homes; but the consequences of the siege were disastrous, for the commerce of the town never recovered the loss of the large working-class population which left it at that time. [Footnote *: 'Thuin,' or 'tuin,' in Flemish means an enclosed space, such as a garden plot.] [Illustration: A FARMSTEADING] The religious troubles of the sixteenth century left their mark on Ypres as well as on the rest of Flanders. Everyone has read the glowing sentences in which the historian of the Dutch Republic describes the Cathedral of Antwerp, and tells how it was wrecked by the reformers during the image-breaking in the summer of 1566. What happened on the banks of the Scheldt appeals most to the imagination; but all over Flanders the statues and the shrines, the pictures and the stores of ecclesiastical wealth, with which piety, or superstition, or penitence had enriched so many churches and religious houses, became the objects of popular fury. There had been field-preaching near Ypres as early as 1562.[*] Other parts of West Flanders had been visited by the apostles of the New Learning, and on August 15, 1566, the reformers swept down upon Ypres and sacked the churches.
