Headpiece (book illustration)

Headpiece (also spelled head-piece), is a decoration printed in the blank space at the beginning of a chapter or other division of a book, usually an ornamental panel, printer's ornament or a small illustration done by a professional illustrator. The use of decorative headpieces in manuscripts was inherited by the medieval West from late Antique and Byzantine book production, and enjoyed particular popularity during the Renaissance.
