The third volume of Alkis Charalampidis' book The Art of the 20th Century is reissued in a revised edition in a volume of approximately 780 pages. The book begins with an introduction to 19th-century art and then examines painting, sculpture, and architecture of the 20th century on a global scale, as well as other forms of artistic expression that dominated the art world, particularly after World War II (Happening, Environment, Body Art, Performance, Land Art, Conceptual Art, Video Art, etc.).

The text, coordinated with updated visual material (1,267 images), adapted to the reader's current requirements, offers substantial knowledge in a continuous flow, helping the reader form their own opinion about a period abundant in artistic quests and achievements.

The author organizes and processes a voluminous, often unruly and scattered material, clarifies terminology issues, simplifies complex analyses, reconciles similar or conflicting views, while also utilizing the words of the creators themselves as well as art historians and critics. Finally, he ensures the autonomy of the sections while maintaining their underlying connection.
