According to the Monier-Williams Sanskrit Dictionary, the sage Taittiri was a pupil of Yaska (estimated 300-400 BCE). According to the Vishnu Purana, Yaska was in turn a pupil of Vaiśampáyana (estimated 500 BCE). Taittiri is also stated in the Mahabharata to have attended 'the Yaga [Vedic ritual sacrifice] conducted by Uparicaravasu' (Dvapara Yuga, before 3000 BCE).
