So a smith sitting beside the anfelt or stithy, and beholding the work of iron, the heat of fire burneth his fleshes or flesh; and he striveth in the heat of the furnace. The voice of a hammer maketh new his ear; and his eye is against the likeness of a vessel. He shall give his heart into the performing of works; and by his waking he shall adorn unperfection, that is, matter which he bringeth to perfection of form.
