The Ramayan by Valmiki

The Wind-God's son a temple scaled Which, by his fury unassailed, High as the hill of Meru, stood Amid the ruins of the wood; And in his fury thundered out Again his haughty battle-shout: "I am the slave of Kosal's King Whose wondrous deeds the minstrels sing." Forth hurried, by that shout alarmed, The warders of the temple armed With every weapon haste supplied, And closed him in on every side, With bands that strove to pierce and strike With shaft and axe and club and pike. Then from its base the Vanar tore A pillar with the weight it bore. Against the wall the mass he dashed, And forth the flames in answer flashed, That wildly ran o'er roofs and wall In hungry rage consuming all. He whirled the pillar round his head And struck a hundred giants dead. Then high upheld on air he rose And called in thunder to his foes: "A thousand Vanar chiefs like me Roam at their will o'er land and sea, Terrific might we all possess: Our stormy speed is limitless. And all, unconquered in the fray, Our king Sugriva's word obey. Backed by his bravest myriads, he Our warrior lord will cross the sea. Then Lanka's lofty towers, and all Your hosts and Ravan's self shall fall. None shall be left unslaughtered; none Who braves the wrath of Raghu's son."
