Chlamys

Chlamys is a term with two principal senses. In classical antiquity, it denotes a rectangular cloak worn by Greeks and later Romans. The cloak was usually made of wool or light linen and measured roughly the width of the wearer, with a length reaching the knee or mid-thigh. It was typically fastened at the right shoulder by a fibula or pin, allowing the left side to drape freely. The chlamys was a practical garment for travelers and light infantry and is often depicted in Greek art worn by soldiers, athletes, and travelers, as well as by gods and heroes in light-color attire. Variants included shorter forms or styles designed for riding or swimming.

In zoology, Chlamys is a genus of scallops within the family Pectinidae. The shells are fan-shaped with radiating ribs and a rounded outline. The genus includes multiple species, such as Chlamys islandica and Chlamys varia; however, modern classifications have reassigned several species to other genera, so circumscription of Chlamys varies with taxonomic revision. Chlamys scallops inhabit temperate and cold continental shelves around the world and are important in marine ecosystems and fisheries.

The name derives from Greek khlamys, meaning a cloak, reflecting the garment’s origin.
