The Ramayan by Valmiki

Their task achieved, the princes spent That night with joy and full content. Ere yet the dawn was well displayed Their morning rites they duly paid, And sought, while yet the light was faint, The hermits and the mighty saint. They greeted first that holy sire Resplendent like the burning fire, And then with noble words began Their sweet speech to the sainted man: "Here stand, O Lord, thy servants true: Command what thou wouldst have us do."

The saints, by Visvamitra led, To Rama thus in answer said: "Janak the king who rules the land Of fertile Mithila has planned A noble sacrifice, and we Will thither go the rite to see. Thou, Prince of men, with us shalt go, And there behold the wondrous bow, Terrific, vast, of matchless might, Which, splendid at the famous rite, The Gods assembled gave the king. No giant, fiend, or God can string That gem of bows, no heavenly bard: Then, sure, for man the task were hard. When lords of earth have longed to know The virtue of that wondrous bow, The strongest sons of kings in vain Have tried the mighty cord to strain. This famous bow thou there shalt view, And wondrous rites shalt witness too. The high-souled king who lords it o'er The realm of Mithila of yore Gained from the Gods this bow, the price Of his imperial sacrifice. Won by the rite the glorious prize Still in the royal palace lies, Laid up in oil of precious scent With aloe-wood and incense blent."
