This 19th-century European architectural Carrara marble monumental relief with Angels and Lamb of God (Agnus Dei) was originally an altar front (paliotto), carved as part of a grander sacred installation.

The solid marble slab panel is a monumental mid-1800s sculpture with a Gothic aesthetic, a masterwork carved in deep relief, featuring a central quatrefoil medallion enclosing the mystical Lamb of God flanked by two beautifully draped figures - saints or angels- inside a deep ogival niches holding a cartouche.
The artistic layout is centered around a beautifully executed hand-carved medallion depicting the Agnus Dei, bearing a cross-emblazoned banner with a sacrificial chalice at its feet. This deep Eucharistic imagery draws heavily from late medieval and Northern European traditions.
The sculpture displays deep undercutting that maximizes shadow play, allowing the forms to dramatically emerge from the background panel. The solid marble slab, exuding an extraordinary sense of historical gravitas, boasts immense technical skill, drawing the viewer's attention to the weightless fluidity of the drapery, the virtuoso carving of the fleece's tightly coiled ringlets, and the refined anatomical precision of the figures’ hands and faces and their flowing robes adding movement and depth to the white marble surface.
This frieze slab stands as a premier acquisition for discerning curators and interior architects, seeking an authentic, commanding statement antique presenting a rare combination of sacred devotion and majestic structural character tailored for high-end residential and commercial collections.

Distinguished Connoisseur Provenance
This exceptional marble structure enters the market with a flawless lineage, sourced directly from the private collection of an esteemed European connoisseur and passionate collector. Meticulously selected for its academic importance and formal beauty, represents a secure and elite buying opportunity for international collectors of sacred art and historical decorative sculpture.

Sculptural Technique, Iconography & Academic Attributes
For international collectors, this iconography carries a dual layered fascination:
The Florentine Guild Connection: This haloed sacrificial lamb imagery strongly mirrors the famous heraldic crest of the historic Arte della Lana (the Guild of Wool Manufacturers), one of Florence's most celebrated symbols of Late Renaissance civic pride.
German-Roman Nineteenth-Century Workshops: The strict geometric control of the pointed architectural arches and the crisp, stylized carving of the lamb's fleece indicate a highly specialized 19th-century workshop blending Italian materials with Northern European artistic precision. The treatment is closely linked to the circle of German sculptor Theodor Wilhelm Achtermann—who operated a prolific studio in Rome from 1839 until his death in 1884 specializing in high-profile religious and devotional commissions—as well as the refined marble reliefs of Arnold Hermann Lossow.
The lateral niches shelter two youthful, haloed figures holding open scrolls. Their fluidly carved vestments and subtle, non-rigid shifts in posture allow them to be interpreted with equal scholarly validity as scroll-bearing angels or as the Evangelists.

Interior Design & Architectural Placement
Given its imposing horizontal dimensions and sculptural depth, this antique marble relief easily transitions into upscale contemporary or classical spaces:
