Single-roller cotton gin emerges in India, documented at the Ajanta Caves
The cotton gin traces back to 5th-century India, where paintings in the Ajanta Caves show the earliest known depiction of a single roller pressed against stone to separate fiber from seed. Contemporary records later noted one man and one woman could clean 28 pounds of cotton a day using an Indian roller gin — a quiet foundation for a technology that would travel across centuries and continents.
