This stained glass panel of Saint Peter 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.

This panel depicts Saint Peter standing beneath a Renaissance architectural canopy. He is shown holding the keys of heaven in his left hand and an open book in his right, symbols of his authority as the first of the apostles and the foundation of the Church. The inscription beneath him reads TIBI DABO CLAVES REGNI CÆLORUM (“To you I will give the keys of the kingdom of heaven”), taken from the Gospel of Matthew.

Peter is dressed in a deep blue tunic with a golden ochre cloak that drapes in heavy folds, rendered with refined enamel painting and subtle shading typical of mid-sixteenth-century glasswork. His calm, thoughtful expression and monumental stance convey dignity and spiritual authority. The balanced architectural frame with its pilasters and entablature reflects the influence of French Renaissance design.
