This window by the Auvergnat glass-painter François Taureilles presents St John the Baptist in the wilderness, rendered with the clarity and restrained richness typical of early-twentieth-century French devotional glass. The saint stands barefoot beside the waters of the Jordan, clothed in a camel-hair tunic overlaid by a violet mantle. In his left hand he cradles the Agnus Dei, while his right holds the tall cross-staff entwined with a scroll reading Ecce Agnus Dei. Behind him, a landscape of rocky hills and riverbank vegetation unfolds in tones of blue and green, the entire composition framed by a border of geometric ornament and stylised floral motifs in red, turquoise, and gold.

Taureilles’s work here blends neo-medieval design with modern graphic precision. The strong contour lines, lucid primary palette, and symmetrical framing recall nineteenth-century precedent, yet the modelling of the face and hands possesses a gentler naturalism. Light filters through the brilliant blue ground, giving the figure a calm luminosity that suits the saint’s role as forerunner and prophet.

Installed during a programme of early-twentieth-century embellishment at La Bourboule’s Church of St Joseph, the window forms part of a cohesive cycle by Taureilles, who supplied several narrative and devotional panels for the nave and aisles. It stands as a fine example of provincial French craftsmanship at the turn of the century—faithful to Gothic tradition yet alive with the clarity and colouristic confidence of modern stained glass.
