Saint Jerome

Saint Jerome, undated and in the Stockport Heritage Services collection alongside the companion Saint Onuphrius, depicts the most commonly painted hermit saint of the Catholic tradition. Jerome — scholar, translator of the Bible into the Vulgate Latin, and desert penitent — appears here in Castiglione's characteristic chiaroscuro treatment as an aged man in rocky wilderness, typically accompanied by his lion and devotional objects. The subject invited painters to combine portraiture, landscape, and devotional symbolism in a single image, and Castiglione's interpretation emphasises the physical atmosphere of the hermit's isolation. The Stockport pair suggests these were conceived as companion devotional pieces, probably for a private oratory.

Jerome's weathered face and aged body are rendered with the same attention to the marks of ascetic life visible in the companion Onuphrius. Cardinal's robes — anachronistically often included — or penitential garments mark his ecclesiastical and scholarly identity. A book or scroll confirms his role as translator and scholar.
