Marko Marulić (Croatian pronunciation; Split, 18 August 1450 – Split, 5 January 1524) was a Croatian national poet and Christian humanist, known as the Crown of the Croatian mediaeval Age and the father of the Croatian Renaissance. He signed his works as Marko Marulić Splićanin ("Marko Marulić of Split"), Marko Pečenić, Marcus Marulus (or de Marulis) Spalatensis, or Dalmata. He was also the first who defined and used the notion of psychology, which is today in current use.
