but an inspired artist and his workshop a sanctuary. Daily he commenced his craft with prayer and purification, or, as the phrase was, “he committed his soul and spirit into the forging and tempering of the steel.” Every swing of the sledge, every plunge into water, every friction on the grindstone, was a religious act of no slight import. Was it the spirit of the master or of his tutelary god that cast a formidable spell over our sword? Perfect as a work of art, setting at defiance its Toledo and Damascus rivals, there was more than art could impart. Its cold blade, collecting on its surface the moment it is drawn the vapour of the atmosphere; its immaculate texture, flashing light of bluish hue; its matchless edge, upon which histories and possibilities hang; the curve of its back, uniting exquisite grace with utmost strength;–all these thrill us with mixed feelings of power and beauty, of awe and terror.
