Eikonoklastes (from the Greek εἰκονοκλάστης, "") is a book by John Milton, published October 1649. In it he provides a justification for the execution of Charles I, which had taken place on 30 January 1649. The book's title is taken from the Greek, and means "Iconoclast" or "breaker of the icon", and refers to Eikon Basilike, a Royalist propaganda work. The translation of Eikon Basilike is "icon of the King"; it was published immediately after the execution. Milton's book is therefore usually seen as Parliamentarian propaganda, explicitly designed to counter the Royalist arguments.
Milton was commissioned to write Eikonoklastes as a response to Charles I's supposed Eikon Basilike (1649). The tract was intended to be the official argument by the Commonwealth government.
Eikon Basilike was published just after Charles I's execution, and the work portrayed him as a martyr. The piece was written with straightforward political aims, to stir up popular sentiment in support of the former monarch and to undermine the control of the Commonwealth government. The work proved so popular that there were 35 editions produced that year. Milton's approach was different from that of Eikon Basilike, which may have in fact been a composite work with John Gauden involved in ghostwriting: instead of appealing to popular sentiment, Milton's work was closely argued and tried to meet each of the points in the Eikon.
Milton believed, certainly, that the Eikon Basilike created a false idol and he wanted to destroy it with truth.Eikonoklastes, titled Eikonolastes in Answer to a Book Intitl'd Eikon Basilike, The Portrature of his Sacred Majesty in his Solitudes and Sufferings, was issued in two versions in October 1649, in English, and was enlarged in 1650. It was quite soon translated into Latin and French. In 1651 a reply appeared, Eikon Aklastos ("the icon unbroken"). It was written by Joseph Jane, involved in royalist organisation.
Milton begins his work by mentioning that he was commissioned to write Eikonoklastes and that he did such for the good of the Commonwealth: "I take it on me as a work assign'd rather, then by me cho'n or affected" The central argument of Eikonoklastes involves the tyranny inherent in all monarchies, and Milton attacks the idea put forth by Charles I that the liberty of individuals consists "in the enjoyment of the fruits of our industry, and the benefit of those Laws to which we our selves have consented". Milton's response is to point out how such a definition cannot actually separate different kinds of governments:
