For this second glance at the representation of the human face across cultures I have decided to show an important selection of masks, illustrating the universality and diversity of a practice that goes back to the mists of time, and its permanency through the ages. This selection is highly personal, the result of encounters but also a cognitive approach in pursuit of truly authentic forms of art and beauty, without necessarily following the trends of the market. This is also inevitably a choice, the reflection of a taste, inherited from the path traced by the Avant-Garde artists, collectors and dealers of the early twentieth century, and expressed in the very title of this catalogue, in reference to early publications and German expressionism. The masks I included in this catalogue respond to this particular aesthetics, through their startling expressiveness and fascinating modernity; but they also share what i believe are common qualities attributed to all great works of art : clarity and eloquence. An original essay by Caterina Magni about the extraordinary masks of the Olmec civilization, with several unpublished masks of importance, will conclude this overview.
