指稱通常以一個點為中心向外旋繞出去所產生的平面曲線。已知的螺線種類相當多，包括古希臘時期的《論螺線》（約西元前225年）中描述的阿基米德螺線，以及何內•笛卡兒於西元1638年首先提出的對數螺線（等角螺線）。人類於自然中觀察發現此種曲線的存在，並廣泛運用於機器及裝飾上，特別是建築領域，例如愛奧尼亞式柱頭上的螺紋。若要指稱較複雜的形式，則使用「漩渦形飾 (紋飾)」或是「渦捲裝飾」等詞彙較佳。

英文....	Plane curves that generally wind around a point while moving ever farther from the point. Many kinds of spiral are known, including the ancient Greek Archimedean spiral, described in On Spirals (ca. 225 BCE), and the logarithmic or equiangular spiral first described by René Descartes in 1638. The curves are observed in nature, and humans have used them in machines and in ornament, notably architecture, for example, the whorl in an Ionic capital. Prefer "scrolls (motifs)" or "scrollwork" for more complex forms.
荷蘭語....	Bij de verwijzing naar ornamenten te gebruiken voor simpele gekronkelde lijnen. Gebruik 'krullen (motieven)' of 'rolwerk' voor de meer ingewikkelde vormen.
西班牙語....	Cuando se refiere a ornamento, usar para líneas simples enrrolladas y prefiera "voluta (motivo)" o "apliqué enrrollado" para formas más complejas.
