The paper presents the basic positions of understanding of Serbian medieval culture and art in the works of the renowned scholar of Serbian literature Pero Slijepčević. During his life and work in Skoplje in the 1930s, Slijepčević was in direct contact with the signifiers of the Serbian cultural tradition, so he became more familiar with sacral art and architecture, history and literature of the Middle Ages. Pero Slijepčević's works on ancient Serbian art, its historical, cultural, sacral and symbolic values, are usually viewed at the margins of their author's overall and highly philological, pedagogical, cultural and social engagement. And yet, they can identify important perspectives on thought and relevant contributions to the contemporary historization of Serbian culture and art. Although these works are somehow hidden, silent in the horizon of Pero Slijepčević's overall work and engagement, his thought about the art of the Middle Ages is as much an indicator of the diversity of Slijepčević's knowledge and authentic gift for the scientific study of that art and time, as much of the depth of cultural experience. Without which even the central dimensions of literary, cultural or educational expression could not be so strongly realized.
