The English physician and philosopher Sir Thomas Browne penned a discourse entitled The Garden of Cyrus in 1658 in which Cyrus is depicted as an archetypal “wise ruler” – while the Protectorate of Cromwell ruled Britain.

One of the few surviving sources of information that can be dated directly to Cyrus’s time is the Cyrus Cylinder (Persian: استوانه کوروش‎), a document in the form of a clay cylinder inscribed in Akkadian cuneiform. It had been placed in the foundations of the Esagila (the temple of Marduk in Babylon) as a foundation deposit following the Persian conquest in 539 BC. It was discovered in 1879 and is kept today in the British Museum in London.

The historical nature of this decree has been challenged. Professor Lester L Grabbe argues that there was no decree but that there was a policy that allowed exiles to return to their homelands and rebuild their temples. He also argues that the archaeology suggests that the return was a “trickle,” taking place over perhaps decades, resulting in a maximum population of perhaps 30,000. Philip R. Davies called the authenticity of the decree “dubious,” citing Grabbe and adding that J. Briend argued against “the authenticity of Ezra 1.1–4 is J. Briend, in a paper given at the Institut Catholique de Paris on 15 December 1993, who denies that it resembles the form of an official document but reflects rather biblical prophetic idiom.” Mary Joan Winn Leith believes that the decree in Ezra might be authentic and along with the Cylinder that Cyrus, like earlier rulers, was through these decrees trying to gain support from those who might be strategically important, particularly those close to Egypt which he wished to conquer. He also wrote that “appeals to Marduk in the cylinder and to Yahweh in the biblical decree demonstrate the Persian tendency to co-opt local religious and political traditions in the interest of imperial control.”

On 10 December 2003, in her acceptance of the Nobel Peace Prize, Shirin Ebadi evoked Cyrus, saying:
