Matsya Purana — Iconographic Standards for the Navagrahas
इन्द्रनीलद्युतिः शूली वरदो गृध्रवाहनः बाणबाणासनधरः कर्तव्यो ऽर्कसुतस् तथा //
indranīladyutiḥ śūlī varado gṛdhravāhanaḥ bāṇabāṇāsanadharaḥ kartavyo 'rkasutas tathā //
Likewise, Śani—the son of Arka (the Sun)—should be fashioned with sapphire-like radiance, bearing a spear, granting boons, riding upon a vulture, and holding arrows and a bow.
This verse does not discuss Pralaya; it gives iconographic specifications for crafting the image of Śani (the Sun’s son) for worship.
It supports the dharma of proper worship and public religiosity: kings and householders are instructed to commission and install correctly formed deity/planetary images to maintain auspicious order and ritual propriety.
It is a pratimā-lakṣaṇa guideline: Śani’s murti should be sapphire-hued and shown with specific attributes (śūla, bow and arrows) and a vulture mount—details used for temple installation, navagraha shrines, and consecration rites.
