And praised all around, the son of Pritha then went, at the command of Indra, to that large and extensive starry way called by the name of Suravithi. — Kisari Mohan Ganguli (1883-96)
A vīthī-name not in the database's Purāṇic star-road set (nāgavīthī, gajavīthī, airāvatī, ārṣabhī, govīthī, jāradgavī, ajavīthī, mṛgavīthī, vaiśvānarī). The epic defines it in apposition: 'the broad NAKṢATRAMĀRGA renowned as Suravīthī' — so Suravīthī is not one of the nine narrow lanes but the whole road of the asterisms, which Arjuna travels by Indra's order on his way to Amarāvatī. The Purāṇic vīthīs subdivide precisely this band, so Suravīthī is best read as the generic name of which they are the subdivisions. Ganguli: 'that large and extensive starry way called by the name of Suravithi.'
