Digha Nikaya 1:1483
SUJATOAtha kho kosinārakā mallā bhagavato sarīrāni sattāhaṁ sandhāgāre sattipañjaraṁ karitvā dhanupākāraṁ parikkhipāpetvā naccehi gītehi vāditehi mālehi gandhehi sakkariṁsu garuṁ kariṁsu mānesuṁ pūjesuṁ.
Then the Mallas made a cage of spears for the Buddha’s relics in the town hall and surrounded it with a buttress of bows. For seven days they honored, respected, revered, and venerated them with dance and song and music and garlands and fragrances.
