Art history is more than just a collection of dates and foreign-sounding names, obscure movements and arcane isms. Every age, for the last 50,000 years has left its unique imprint on the world, and from the first cave paintings to the ceiling of the Sistine Chapel, from the Byzantine mosaics of the Hagia Sophia, to the graffiti-inspired paintings of Jean-Michel Basquiat, art history tells the story of our evolving notions of who and what we are and our place in the universe.
