Mbh 4.5.5a

Vaisampayana continued, “Having O bull of the Bharata race spoken thus to king Yudhishthira the just, Arjuna prepared to deposit the weapons (on the tree). And that bull among the Kurus, then loosened the string of the large and dreadful Gandiva, ever producing thundering twang and always destructive of hostile hosts, and with which he had conquered, on a single car, gods and men and Nagas and swelling provinces. And the warlike Yudhishthira, that represser of foes, unfastened the undecaying string of that bow with which he had defended the field of Kurukshetra. And the illustrious Bhimasena unstrung that bow by means of which that sinless one had vanquished in fight the Panchalas and the lord of Sindhu, and with which, during his career of conquest, he had, single-handed, opposed innumerable foes, and hearing whose twang which was like unto the roar of the thunder or the splitting of a mountain, enemies always fly (in panic) from the field of battle. And that son of Pandu of coppery complexion and mild speech who is endued with great prowess in the field, and is called Nakula in consequence of his unexampled beauty in the family, then unfastened the string of that bow with which he had conquered all the regions of the west. And the heroic Sahadeva also, possessed of a mild disposition, then untied the string of that bow with which he had subjugated the countries of the south. And with their bows, they put together their long and flashing swords, their precious quivers, and their arrows sharp as razors. And Nakula ascended the tree, and deposited on it the bows and the other weapons. And he tied them fast on those parts of the tree which he thought would not break, and where the rain would not penetrate. And the Pandavas hung up a corpse (on the tree), knowing that people smelling the stench of the corpse would say--‘here sure, is a dead body,’ and avoid the tree from a distance.
