This mural by Coghuf, titled 'Les quatre heures,' transforms a school courtyard wall into a window onto a different world. Created in 1938 for a kindergarten, it presents a panoramic Jura landscape not as a wild idyll but as a cultivated, working terrain. The central scene of farmers taking their four o'clock break is rendered with monumental, simplified figures, making the laborers larger than life. This artistic choice serves a clear pedagogical purpose for its young urban audience: to vividly connect the food on their plates to the physical toil of rural life, embedding a lesson about origin and labor directly into the architecture of their play space. The artwork acts as a silent, enduring teacher within the school's walls.
