Also, a particular theme might very well turn up again even when the time of full attention to that theme has passed. However after careful analysis, scholars have been able to break Escher's work down into four workable time periods: 1922-1937 = the Landscape Period, 1937-1945 = Metamorphosis Period, 1946-1956 = Perspective Prints Period and 1956-1970 = Infinity Period. .
