Over time, a separate set of texts delineating the Rshi, Devata, Chanda, etc for each of the Vedas were created by the Acharyas that came to be known as Anukramanis. The Yajusha Anukramani is known as Shukla Yajuh Sarvanukrama Sutra written by Katyayana. It consists of 5 adhyayas and is endowed with the commentary of Mahayajnika Shrideva (son of Mahayajnika Prajapati). It describes the devata, rshi and Chanda of the Madhyandina Samhita.
