Āpastamba Dharmasūtra (Sanskrit: आपस्तम्ब धर्मसूत्र) is a Sanskrit text and one of the oldest Dharma-related texts of Hinduism that have survived into the modern age from the 1st millennium BCE.[1] It is one of three extant Dharmasutras texts from the Taittiriya school of Krishna Yajurveda, the other two being Baudhayana Dharmasutra and Hiranyakesin Dharmasutra.[2]
The Apastamba Dharmasutra is part of Apastamba Kalpasutra collection, along with Apastamba Shrautasutra and Apastamba Grihyasutra.[2] One of the best preserved ancient texts on Dharma,[3] it is also notable for mentioning and citing views of ten ancient experts on Dharma, which has led scholars to conclude that there existed a rich genre of Dharmasutras text in ancient India before this text was composed.[4][5]
