George Kubler: The Shape of Time: Remarks on the History of Things (1962–) [EN, ES, IT, PT]

“When it was released in 1962, The Shape of Time presented a radically new approach to the study of art history. Drawing upon new insights in fields such as anthropology and linguistics, George Kubler replaced the notion of style with the idea of a linked succession of works distributed in time as recognizably early and late versions of the same action. The result was a view of historical sequence aligned on continuous change more than upon the concept of style–the then usual basis for histories of art.”
