Note 143 — Chapter III · CONDUCT IN CAPTIVITY.
Reading edition
The iron goad with which the keeper directs the movements of the elephants, called a hendoo in Ceylon and hawkus in Bengal, appears to have retained the present shape from the remotest antiquity. It is figured in the medals of Caracalla in the identical form in which it is in use at the present day in India.

Medal of Numidia.

Modern Hendoo.
The Greeks called it ἅρπη, and the Romans cuspis.
