18 The Song of the Minster would blend in one indescribable volume of harmony, which made the huge pile thrill and vibrate from roof to pavement. As Thomas listened, his eyes became ac- customed to the celestial light which encom- passed him, and he saw —he could scarce credit his senses that he saw—the little carved angels of the oak stalls in the choir clashing their cymbals and playing their psalteries. He rose to his feet, bewildered and half terrified. At that moment the mighty roll of unison ceased, and from many parts of the church there came a concord of clear high voices, like a warbling of silver trum- pets, and Thomas heard the words they sang. And the words were these — Tibi omnes Angeli. To Thee all Angels cry aloud. So close to him were two of these voices that Thomas looked up to the spandrels in the choir, and he saw that it was the carved angels leaning out of the spandrels that were singing. And as they sang the breath came from their stone lips white and vaporous into the frosty air.
