पुटमेतत् सुपुष्टितम्

the Sāma Veda. Its authorship is attributed to Śākaṭāyana according to Nageśa, while औदिव्राज is held as its author by some, and कात्यायन by others. It bears a remarkable similarity to Pāṇini's Aṣṭādhyāyī especially in topics concerning co- alescence and changes of स् and न् to ष् and ण् respectively. It cannot be definitely said whether it pre- ceded or followed Pāṇini's work.

ऋक्प्रातिशाख्य one of the Prātiśākhya works belonging to the Aśvalāyana Śākha of the Ṛg Veda. The work available at present, appears to be not a very old one,possibly written a century or so after Pāṇini's time. It is possible that the work, which is available, is based upon a few ancient Prātiśākhya works which are lost. Its authorship is attribu- ted to Śaunaka.The work is a metrical one and consists of three books or Adhyāyas, each Adhyāya being made up of six Paṭalas or chapters. It is written, just as the other Prātiśākhya works, with a view to give directions for the proper recitation of the Veda. It has got a scholarly commentary written by Uvaṭa and another one by Kumāra who is also called Viṣṇumitra. See अाश्वलायनप्रातिशाख्य.
