Medieval Reliquary Panel or Altar Frontal Section with Saint Michael

This appears to be a section of a medieval reliquary panel or perhaps part of an altar frontal, characterized by its elaborate craftsmanship and devotional subject matter. The central figure, likely St. Michael the Archangel, is depicted in high relief, possibly in repoussé technique, against a darker, tarnished metal background. He is shown in a standing posture, wearing ornate robes that cascade in elegant folds, holding what appears to be a staff or spear in his right hand and a shield or book in his left. A small, dragon-like creature is visible at his feet, referencing the Archangel's victory over evil. The figure's halo is prominent, and facial features are stylized in a manner typical of medieval religious art. The central panel is framed by a broad, intricately decorated golden border, likely gilded bronze or copper, featuring punched or engraved patterns of foliage and geometric designs. Along the border, small, cabochon-style stones or glass inlays are set, varying in color from white to subtle blue-green, adding to its precious appearance. The frame is secured with visible rivets or small nails, indicating its construction. The overall style suggests a Romanesque or early Gothic period, perhaps 11th to 13th century. The item exhibits significant patina and tarnish consistent with age, particularly on the relief figure, which has a darker, oxidized finish compared to the brighter golden frame. Some areas of the gilt frame show wear, revealing the underlying metal. This piece demonstrates remarkable craftsmanship with attention to detail in both the figural representation and the decorative elements, indicative of high-quality ecclesiastical artistry.
