"dynamite grooves, burns, and
hatchet strokes,..."See in text(The Fish)
Moore employs personification in two ways here, giving both the cliff and the sea human characteristics. The cliff, that “defiant edifice” with its “lack of cornice” takes on a human-made quality. Moore also uses artificial imagery—”burns, and/hatchet strokes”—to describe the sea’s assault on the cliff. There is a human violence to the scene.
