Linothorax

Linothorax is a type of composite armor that was used by the ancient Greeks, particularly in the fourth and third centuries B.C. The name comes from the Greek words for linen (linos) and breastplate (thorax). The construction of a linothorax involved several layers of hand‑stitched linen, often papered or folded, which were pressed between sheets of cork or other soft, dense material. In some examples, a metal backing such as bronze or iron plates were added to reinforce the structure or to attach a fastening system, but many surviving specimens do not include metal elements.

The earliest surviving example of a linothorax was discovered in the Eleusis dressing table, dated to the late fifth century B.C. In the following centuries, it was widely used by Greek hoplite and cavalry units because the armor offered a defensive surface that was both lighter and more flexible than bronze cuirasses. Linothorax was also noted for its ability to absorb impact; the layered linen could flex and thus distribute force more evenly.

Archaeological sites such as the Acropolis, the sanctuary of Demeter in Eleusis, and the Thracian city of Philippi have yielded fragments of this material. While the practice fell out of use as metal armor became more readily available, the linothorax remains an important example of ancient Greek ingenuity in the use of available resources for warfare.
