The Trojans advanced in a dense body, with Hector at their head pressing right on as a rock that comes thundering down the side of some mountain from whose brow the winter torrents have torn it; the foundations of the dull thing have been loosened by floods of rain, and as it bounds headlong on its way it sets the whole forest in an uproar; it swerves neither to right nor left till it reaches level ground, but then for all its fury it can go no further- even so easily did Hector for a while seem as though he would career through the tents and ships of the Achaeans till he had reached the sea in his murderous course; but the closely serried battalions stayed him when he reached them, for the sons of the Achaeans thrust at him with swords and spears pointed at both ends, and drove him from them so that he staggered and gave ground; thereon he shouted to the Trojans, Trojans, Lycians, and Dardanians, fighters in close combat, stand firm: the Achaeans have set themselves as a wall against me, but they will not check me for long; they will give ground before me if the mightiest of the gods, the thundering spouse of Juno, has indeed inspired my onset.
