The origins of Euphuism and of that later form of preciousness which is sometimes called Gongorism and sometimes Marinism have been much discussed, but the last word has certainly not been said on them.
"A History of English Literature Elizabethan Literature"
George Saintsbury

"The English Novel in the Time of Shakespeare"
J. J. Jusserand
