Ironwork is any weapon, artwork, utensil, or architectural feature made of iron, especially one used for decoration. There are two main types of ironwork: wrought iron and cast iron. While the use of iron dates as far back as 4000 BC, it was the Hittites who first knew how to extract it and develop weapons. Use of iron was mainly utilitarian until the Middle Ages; it became widely used for decoration in the period between the 16th and 19th century.

The scroll in art is an element of ornament and graphic design featuring spirals and rolling incomplete circle motifs, some of which resemble the edge-on view of a book or document in scroll form, though many types are plant-scrolls, which loosely represent plant forms such as vines, with leaves or flowers attached. Scrollwork is a term for some forms of decoration dominated by spiralling scrolls, today used in popular language for two-dimensional decorative flourishes and arabesques of all kinds, especially those with circular or spiralling shapes.
