The Junagarh Rock inscription of Rudradaman is considered as an early example of chaste Sanskrit, written in mid second century AD. It mentions that one of Chandragupta Maurya’s governors, Pushyagupta, was responsible for building a dam on Sudarshana Lake near Girnar in Kathiawar. From another inscription of Skandgupta we came to know that this very dam was repaired during his reign, almost 800 years after it was built
