10.95: dialogue of Pururavas and Urvashi (18 trishtubhs)
10.183: dialogue between the sacrificer and his wife (3 trishtubhs) The Rigveda contains a number of dialogue hymns (s) in the form of dialogues, representing the earliest surviving sample of this genre. It can be argued to be an early precursor of Indian classical drama. They are found in the youngest part of the Rigveda (RV 1 and RV 10), dating to roughly the 12th to 10th centuries BC, with the exception of the older River hymn (RV 3.33), where the rivers answer in reply to Vishvamitra’s prayer.
