The Song of the Minster 21 the strains of joyous worship changed into a wail of supplication ; and as he caught the words, Thomas too raised his voice in wild entreaty : Miserere nostri, Domine, miserere nostri. O Lord, have mercy upon us: have mercy upon us. And then his senses failed him, and he sank to the ground in a long swoon. When he came to himself all was still, and all was dark save for the little yellow flower of light in the sanctuary lamp. As he crept back to his cell he saw with unsealed eyes how churlishly he had grudged God the glory of man’s genius and the service of His dumb creatures, the metal of the hills, and the stone of the quarry, and the timber of the forest ; for now he knew that at all seasons, and whether men heard the music or not, the ear of God was filled by day and by night with an everlasting song from each stone of the vast Minster : We magnify Thee, And we worship Thy name: ever world without end.
