Nor smoke-dulled slip of greenery in a window;
And every old cathedral let him paint,
The columns ranged as in some grove of pines,
And windows richer than the sunset clouds, 35
Wherein the Christ for centuries has smiled,
And rich-robed haloed saints regarded Him;
The Colleges of Leyden and Utrecht,
The solemn libraries, with portraits hung
Of Gerard and à Kempis, let him paint, 40
And let him paint the Liberator’s grave:
