Reconstruction of an Iceman's woven-grass sheath
But thanks to weavers, cloth began to replace hides, and after 10,000 B.C. in the temperate Near East, farmers discovered that light linen was a lot more comfortable than sweaty loinskins.
At first the primitive pagne looked like fake animal skin - unable to forget the old ways of animal magic, early men tufted the cloth to make it look like fleece. They wore their new fleeced cloth draped around their shoulders, but the heat of the sun and the need to free their shoulders for work forced them to drop the pagne to their waist, in what became the first loincloth.
As seen in the movie, John Carter
A loincloth by an other name was a breech clout (old English), waistcloth, dhoti (India), moocha (South Africa), or hipping (Scottish).
In the Middle Ages they were called slops; the French called them cache sexe - hidden sex.
