The book is intended as a survey of some of the most important work of the twentieth century in different disciplines (philosophical, scientific, historical), in order to outline a multiplicity of responses and meanings and a plurality of pronunciations of the term ‘time', which can be very useful for reading many of the manifestations of contemporary art from a different perspective. In particular, the figures and forms of time that result from these readings seem to be intrinsic properties of “artistic objects”, a sort of “theory” of internal time-clocks that manifest themselves according to different grammars and syntaxes: the notions of moment, instant, becoming, interval, event, constitute the elements and reveal how time can be manipulated in a very wide range of ways, of speeds, shifts, rhythms, intervals, retroactions, giving rise to an equally wide variety of figures. All of this is constantly accompanied by attention to the salient aesthetic phenomena of the contemporary world.

Mario Bertoni was born in Modena, graduated in Philosophy from the University of Bologna, researcher in scientific history, journalist, curator of exhibitions and monographs on contemporary artists.
