Kavus orders men to gather baby eagles and rear them on flesh. When they are fully grown he ties four eagles to the corners of a mobile throne and puts legs of lamb on stakes above the eagles' heads. The hungry birds fly up towards the meat and bear the throne into the heavens. But soon the birds grow tired and the contraption crashes to the ground.
[The text common to all the manuscripts states that Kavus wanted to fly in order to fathom the secrets of the heavenly spheres, but some manuscripts have additional verses (Mohl's vss. 475-478; Khaleghi prints them on p. 97, fn. 3) offering two alternative explanations: that he wanted to reach (bar-rasad; other Mss. have 'interrogate' baaz-pursad) the angels, and that he wanted to make war on the heavens with bow and arrow. Some of the illustrations show an angel (with a black fish in its hand; is this the constellation Pisces?), and some (same or different) pictures show the king aiming an arrow upwards, or indeed shooting the afore-mentioned fish.]
