In this period the well known naive painter Theophilos comes to stay in Mount Pilion, where he produced a great part of his work.

Born in Mytilene, nourished by tradition, legends, without any artistic education or training whatsoever, Theophilos followed his instincts and created naive compositions illustrating Greece, tradition, nature, its myths, offering a means of expression that the intellectuals of the inter-war period recognized as quintessentially Greek. The Greekness of Theophilos consists, on the one hand, of his capacity to render with the simplest means the light of his country, the Greek atmosphere and the Greek landscape, and, on the other, of his Greek themes, which demonstrate that he experienced Greek tradition as an uninterrupted sequence. Despised and mocked at the beginning, his art was later recognized and Theophilos was elevated to a teacher of Greekness in art and as a unique case in modern Greek painting.
