Thus having said, the father of the fires To the black labours of his forge retires. Soon as he bade them blow, the bellows turn’d Their iron mouths; and where the furnace burn’d, Resounding breathed: at once the blast expires, And twenty forges catch at once the fires; Just as the god directs, now loud, now low, They raise a tempest, or they gently blow; In hissing flames huge silver bars are roll’d, And stubborn brass, and tin, and solid gold; Before, deep fix’d, the eternal anvils stand; The ponderous hammer loads his better hand, His left with tongs turns the vex’d metal round, And thick, strong strokes, the doubling vaults rebound.
