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.

& 其时，特洛伊人队形密集，迎面扑来，赫克托耳领头先行，杀气腾腾，像石壁上崩下的一块滚动的巨岩，被泛涌着冬雨的大河从穴孔里冲下，凶猛的水浪击散了岩岸的抓力，无情的坠石狂蹦乱跳，把山下的森林震得呼呼作响，一路拼砸滚撞，势不可挡，一气冲到平原，方才阻止不动，尽管肆虐凶狂。就像这样，赫克托耳最初试图一路冲杀，扫过阿开亚人的营棚和海船，直插海边。然而，当接战对方人群密集的队伍，他的攻势受到强有力的止阻，被硬硬地顶了回来。阿开亚人的儿子们群起攻之，用劈剑和双刃的枪矛击打，把他抵挡回去，逼得他连连后退，步履踉跄。他放开嗓门，用尖亮的声音对着全军喊叫：&特洛伊人，鲁基亚人和达耳达尼亚人，近战杀敌的勇士们！和我站在一起！阿开亚人不能长时间地挡住我的进攻，虽然他们阵势密集，像一堵墙似地横阻在我的前头。我知道，他们会在我的投枪下败退，如果我真的受到神明的驱使，一位最了不起的尊神，赫拉抛甩炸雷的夫婿。
