White Devil [EPUB ebook] 

The White Devil (full original title: The White Divel; or, The Tragedy of Paulo Giordano Ursini, Duke of Brachiano. With The Life and Death of Vittoria Corombona the famous Venetian Curtizan) is a tragedy by English playwright John Webster (c. 1580 — c. 1634). The story is loosely based on an event in Italy thirty years prior to the play’s composition: the murder of Vittoria Accoramboni in Padua on 22 December 1585. Webster’s dramatisation of this event turned Italian corruption into a vehicle for depicting "the political and moral state of England in his own day", particularly the corruption in the royal court. The play explores the differences between the reality of people and the way they depict themselves as good, "white", or pure.
