"Finnegans Wake" incorporates a high number of intertextual allusions and references to other texts; Parrinder refers to it as "a remarkable example of intertextuality" containing a "wealth of literary reference." Among the most prominent are the Irish ballad "Finnegan's Wake" from which the book takes its name, Italian philosopher Giovanni Battista Vico's "La Scienza Nuova", the Egyptian Book of the Dead, the plays of Shakespeare, and religious texts such as the Bible and Qur'an. These allusions, rather than directly quoting or referencing a source, normally enter the text in a contorted fashion, often through humorous plays on words. For example, Hamlet Prince of Denmark becomes "Camelot, prince of dinmurk" and the Epistle to the Hebrews becomes a "farced epistol to the hibruws".
