Cyrus Cylinder

The Cyrus Cylinder or Cyrus Charter is an ancient clay cylinder, on which is written a declaration in Akkadian cuneiform script in the name of Persia's Achaemenid king Cyrus the Great. It dates from the 6th century BC and was discovered in the ruins of the ancient Mesopotamian city of Babylon in 1879. It is currently in the possession of the British Museum. It was created and used as a foundation deposit following the Persian conquest of Babylon in 539 BC.
