Detail from the mosaics in the apse vault of the Euphrasian Basilica, Poreč, Croatia
Like the other female saints in the margin of the vault, Agatha is pictured frontally and has a halo of concentric colors. Each of the saints wears a white veil, a single-stranded necklace of dark beads, and a simple dalmatic, gold in color, with an embroidered collar.
