Matsya Purana — Iconographic Standards for the Navagrahas
*शिव उवाच पद्मासनः पद्मकरः पद्मगर्भसमद्युतिः सप्ताश्वः सप्तरज्जुश्च द्विभुजः स्यात्सदा रविः //
*śiva uvāca padmāsanaḥ padmakaraḥ padmagarbhasamadyutiḥ saptāśvaḥ saptarajjuśca dvibhujaḥ syātsadā raviḥ //
Śiva said: Ravi (the Sun-god) should always be depicted seated upon a lotus, holding lotuses in his hands, radiant like the inner glow of a lotus-bud, drawn by seven horses and furnished with seven reins, and shown with two arms.
This verse does not address pralaya; it gives pratima-lakṣaṇa (iconographic) specifications for depicting Ravi/Sūrya in temple art.
Indirectly, it guides righteous patronage: kings and householders commissioning temples or images should follow śāstric iconography so worship is performed with a correctly defined form (mūrti-lakṣaṇa).
It provides a precise checklist for Surya’s image—lotus seat, lotus in hand, lotus-like radiance, seven horses and seven reins, two arms—useful for temple sculpture, consecration (pratiṣṭhā), and ritual visualization.
