Think, in this batter'd Caravanserai
Whose Portals are alternate Night and Day,
How Sultan after Sultan with his Pomp
Abode his destined Hour, and went his way.
They say the Lion and the Lizard keep
The courts where Jamshyd gloried and drank deep:
And Bahram, that great Hunter—the Wild Ass
Stamps o'er his Head, but cannot break his Sleep.
