The new Pakistani authorities requested the return of the Mohenjo-daro pieces excavated on their territory, but the Indian authorities refused. Eventually an agreement was reached, whereby the finds, totalling some 12,000 objects (most sherds of pottery), were split equally between the countries; in some cases this was taken very literally, with some necklaces and girdles having their beads separated into two piles. In the case of the "two most celebrated sculpted figures", Pakistan asked for and received the so-called Priest-King figure, while India retained the much smaller Dancing Girl. Though written considerably later, the arts treatise Natya Shastra () classifies musical instruments into four groups based on their means of acoustical production—strings, membranes, solid materials and air—and it is probable that such instruments had existed since the IVC. Archeological evidence indicates the use of simple rattles and vessel flutes, while iconographical evidence suggests early harps and drums were also used. An ideogram in the IVC contains the earliest known depiction of an arched harp, dated sometime before 1800 BCE. Human statuettes A handful of realistic statuettes have been found at IVC sites, of which much the most famous is the lost-wax casting bronze statuette of a slender-limbed Dancing Girl adorned with bangles, found in Mohenjo-daro. Two other realistic incomplete statuettes have been found in Harappa in proper stratified excavations, which display near-Classical treatment of the human shape: the statuette of a dancer who seems to be male, and the Hapappa Torso, a red jasper male torso, both now in the Delhi National Museum. Sir John Marshall reacted with surprise when he saw these two statuettes from Harappa: These statuettes remain controversial, due to their advanced style in representing the human body. Regarding the red jasper torso, the discoverer, Vats, claims a Harappan date, but Marshall considered this statuette is probably historical, dating to the Gupta period, comparing it to the much later Lohanipur torso. A second rather similar grey stone torso of a dancing male was also found about 150 meters away in a secure Mature Harappan stratum. Overall, anthropologist Gregory Possehl tends to consider that these statuettes probably form the pinnacle of Indus art during the Mature Harappan period. Seals Thousands of steatite seals have been recovered, and their physical character is fairly consistent.
