The crazy discipline of art-history is a multi-refractive sort of humanistic speculation on the highest cognitive and aesthetic level; it is also quite useless like poetry culture and life so naturally I am infatuated with it. Here are some interesting books and worthy authors for your most esteemed consideration:
e.g. Sedlmayr, Belting, Warburg, Wölfflin, Alpers, Didi-Huberman, Panofsky etc.
