Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
पृथुलाक्षसुतश्चापि चम्पनामा बभूव ह चम्पस्य तु पुरी चम्पा पूर्वं या मालिनी भवत् //
pṛthulākṣasutaścāpi campanāmā babhūva ha campasya tu purī campā pūrvaṃ yā mālinī bhavat //
Und der Sohn des Pṛthulākṣa hieß wahrlich Campa. Campas Stadt war Campā; zuvor war sie als Mālinī bekannt.
This verse does not address Pralaya; it records genealogical succession and the renaming/identification of a city (Campā), indicating historical-geographical memory rather than cosmological dissolution.
Indirectly, it reflects the kingly function of founding, maintaining, and lending identity to cities—royal lineage is tied to settlement-building and civic continuity, a key theme in Puranic models of righteous rule.
No explicit Vastu or ritual rule is stated; the main takeaway is toponymy—cities are associated with founders and may bear earlier names, a useful cue when mapping Matsya Purana place-traditions for heritage and temple-town studies.
