This adjective describes what is conspicuous, notable, or distinguished—what comes to light and commands attention. In Acts 2:20, Peter quotes Joel about the sun turning dark before 'the great and glorious day of the Lord.' Classical usage ranged from gods appearing to aid mortals, to prominent terrain features, to distinguished persons of rank. The word carries both visibility (manifest, evident) and quality (glorious, notable). The multilingual evidence shows interpretive variation: English 'glorious' emphasizes splendor, Spanish manifiesto emphasizes visibility, French remarquable stresses notability.
