Śrīpura-Nirmāṇa-Prastāva (Inquiry into Śrīpura and its Construction) / “The Proposal to Build Śrīpura”
द्वारेद्वारे गोपुराणि पर्वलक्षणभाञ्जि च / कालायसस्य कांस्यस्य योंऽतर्देशः समन्ततः
dvāredvāre gopurāṇi parvalakṣaṇabhāñji ca / kālāyasasya kāṃsyasya yoṃ'tardeśaḥ samantataḥ
At every gate there are gopuras bearing the marks of their tiered form; and the inner region between Kālāyasa (dark iron) and Kāṃsya (bronze) extends all around on every side.
