This stained glass panel of John the Baptist in the Church of Saint-Jean-Baptiste at Montrésor, dates from around 1550, and forms part of the large west façade window above the main doorway. This window, composed of three lights, depicts Saint Peter, Saint John the Baptist, and Saint John the Evangelist beneath elegant architectural canopies. The panels were restored in the 19th century after suffering damage during the French Revolution of 1793; the restoration work was carried out by the Parisian glassmaker Eugène Oudinot.

The glass is attributed to the workshop of Robert Pinaigrier, a leading master of the French Renaissance active in the Touraine region during the mid-sixteenth century. Scholars generally describe the attribution as to the “Pinaigrier workshop,” reflecting the collaborative nature of glassmaking at the time. Within the same window, a number of heraldic roundels survive, recalling the church’s founders and patrons, notably the Batarnay family and their alliances.

The John the Baptist panel itself displays the hallmarks of the Pinaigrier style: a gracefully proportioned figure shown with his traditional cross-staff and scroll inscribed “Ecce Agnus Dei”, rendered in finely painted enamel on white glass. The modelling of the flesh and drapery reveals the influence of French Renaissance classicism, while the intricate canopy framing the saint echoes contemporary architectural ornament. Together with the related Passion scenes preserved in the apse, this window forms part of a coherent mid-sixteenth-century glazing program that once filled the church with richly colored biblical imagery.
