At the beginning of the 20th-century, trends started to emerge that began to diverge from a naturalistic conception of reality and set out to explore beneath the mere superficial appearance of things. Throughout, the author shows that, regardless of the multitude of stylistic backgrounds in individual Western countries, everywhere, realisation that a work of art was no longer made in the spirit of the old aesthetics of imitation as if taken from nature, but rather rises from its own independent dimension of existence. A work of art is now autonomous. In this book, the author traces and analyses the origins and the history of abstract art as well as iconic movements and groundbreaking visionaries in an original and exciting way.
