Purāṇas · c. 3rd-5th c. CE
उत्तरं [य]दगस्त्यस्य अजवीथ्याश्च दक्षिणम् । पितृयानः स वै पन्था वैश्वानरपथाद्बहिः ॥ ८५ ॥
On the north of Agastya, and south of the line of the Goat, exterior to the Vaiswánara path, lies the road of the Pitris. / The path of the gods lies to the north of the solar sphere, north of the Nágavithi, and south of the seven Rishis. — H.H. Wilson (1840; public domain)
Valuable for a star database because these are defined ASTRONOMICALLY, by named stellar boundary markers rather than by myth: Agastya (Canopus) and Ajavīthī bound the Pitṛyāṇa; Nāgavīthī and the Saptarṣis bound the Devayāna. Attested identically in three recensions.
