Harlta belonged to the galaxy of the six brilliant pupils of Atreya. He, too, is reputed to have composed a Samhita, but his work is also not available.
There is a Harita reputed to have learnt at the feet of the great sage Jabali and to be the author of Dharma and Smrti books. Whether this Harlta is the same as the co-student of Agnivesa is not certain.
Another Harlta quotes from Vagbhatta and hence is of much later origin and hence of no concern to our present theme.
Harita the pupil of Atreya, is quoted in many famous medical works and is often referred to as old Harita. The following specimen quotations selected at random shows how widely he was reputed as an authority.
