tracery

Because of the flamelike undulations of its window tracery, the Norman archæologist, M. de Caumont, who had brought into use the name Romanesque, invented the equally useful term Flamboyant.

He is homesick for the hale rough weather; for the tracery of the frost upon his window-panes at morning, the reluctant descent of the first flakes, and the white roofs relieved against the sombre sky.
