In the old days, Greek messengers who visited India were in awe about “wool that grew on trees”. Which fibre were they talking about?
Cotton
Cotton was first cultivated in India. The early Greeks who visited India were surprised to find cotton plants that produced fibre that could be turned into clothes. The Greeks depended on wool and fur for their clothing which were expensive and difficult to turn into fabric. India was the chief exporter of cotton until the British conquest of India in the 19th century.
