The truth about Gothic is, first, that it is alive, and second, that it is on the march. It is the Church Militant; it is the only fighting architecture. All its spires are spears at rest; and all its stones are stones asleep in a catapult. In that instant of illusion, I could hear the arches clash like swords as they crossed each other. The mighty and numberless columns seemed to go swinging by like the huge feet of imperial elephants. The graven foliage wreathed and blew like banners going into battle; the silence was deafening with ail the mingled noises of a military march; the great bell shook down, as the organ shook up its thunder. The thirsty-throated gargoyles shouted like trumpets from all the roofs and pinnacles as they passed; and from the lectern in the core of the cathedral the eagle of the awful evangelist clashed his wings of brass.
And amid all the noises I seemed to hear the voice of a man shouting in the midst like one ordering regiments hither and thither in the fight; the voice of the great half-military master-builder; the architect of spears. I could almost fancy he wore armour while he made that church; and I knew indeed that, under a scriptural figure, he had borne in either hand the trowel and the sword.
From the Architect of Spears by G. K. Chesterton
