Illuminated Narratives: Monumental Stained Glass by Fray Arnaldo Marcolino Maas

For centuries, stained glass has served as one of the most powerful storytelling mediums in sacred art. Through luminous color, symbolic imagery, and architectural scale, artists have used glass to transform light into narrative. A group of mid-20th-century stained glass panels by Brazilian Franciscan artist Fray Arnaldo Marcolino Maas exemplifies this enduring tradition. These works, originally created for ecclesiastical settings, reveal both devotional intent and the bold visual language of modern sacred art.

Large Signed Stained Glass Panel “Annunciation” – Fray Arnaldo Marcolino Maas, 1950
The monumental stained glass panel Annunciation stands as the most architecturally ambitious of the group. Measuring approximately 75 inches in height, the composition depicts the angel Gabriel announcing the birth of Christ to the Virgin Mary. Rich cobalt blues dominate the background, while vivid reds, greens, and warm flesh tones animate the figures with dramatic clarity. A Latin inscription, “Et Verbum Caro Factum Est” (“And the Word was made flesh”), integrates theological meaning directly into the design.
Housed in a substantial wooden architectural frame, the panel maintains a strong presence suitable for installation in a chapel or gallery. The work originates from a private collection and has been appraised in the $35,000–$40,000 range, reflecting both its scale and rarity.

Signed Stained Glass Panel “St. Francis of Assisi” – Fray Arnaldo Marcolino Maas, 1949
Created one year earlier, the stained glass panel portraying St. Francis of Assisi offers a more intimate yet equally expressive devotional image. The saint appears in prayerful posture, surrounded by symbolic birds, celestial motifs, and a radiant angel. Maas employs striking contrasts between deep blues, glowing gold tones, and a dramatic red background to emphasize spiritual transcendence.
Mounted in its original iron architectural frame, the panel suggests installation within a church or devotional interior. At approximately 47 inches tall, it exemplifies the mid-century ecclesiastical style that balances traditional iconography with modern design sensibilities. The estimate of $17,000–$23,000 reflects strong collector interest in religious stained glass of this period.

Lot 3: “Industry of Their Hands,” 1954
Departing from strictly hagiographic imagery, Industry of Their Hands introduces a narrative centered on labor and craftsmanship. The multi-figure composition depicts a craftsman at work amid symbolic tools and architectural forms, presenting a visual meditation on the dignity of skilled labor. Spanish inscriptions incorporated into the panel reference hope and faith expressed through work, reinforcing the spiritual dimension of everyday activity.
Although smaller in scale, measuring roughly 26.5 by 17 inches, the panel retains strong visual impact through jewel-toned reds, greens, and ambers framed by cobalt blue glass. The iron frame and ecclesiastical style further connect the work to institutional settings such as schools or churches. With an estimate of $15,000–$22,000, the piece offers collectors a compelling example of thematic diversity within Maas’s stained glass production.

Signed Stained Glass Panel “Beato Martin” (St. Martin de Porres) – Fray Arnaldo Marcolino Maas, 1954
Also dating to 1954, the panel depicting St. Martin de Porres continues Maas’s exploration of saintly compassion and devotion. The Dominican lay brother is portrayed holding a cat, referencing traditions surrounding his kindness toward animals and the poor. Bold mid-century linework and expressive facial modeling give the figure both psychological depth and visual immediacy.
The vibrant palette of deep reds, cobalt blues, and amber glass enhances the vertical composition, while the inscription “B. Martin” identifies the subject’s venerated status. Mounted within an iron architectural frame, the panel maintains the structural presence characteristic of liturgical installations. Its estimate of $15,000–$20,000 positions it as an accessible yet historically resonant acquisition for collectors of religious art.
