1.15 Panchajanya and Devadatta Sanjaya speaks

पाञ्चजन्यं हृषीकेशो देवदत्तं धनंजयः
पौण्ड्रं दध्मौ महाशङ्खं भीमकर्मा वृकोदरः

pāñchajanyaṁ hṛiṣhīkeśho devadattaṁ dhanañjayaḥ
pauṇḍraṁ dadhmau mahā-śhaṅkhaṁ bhīma-karmā vṛikodaraḥ

Krishna blew the Panchajanya, Arjuna the Devadatta, and Bhima of terrible deeds blew the great conch Paundra.

Explanation

The conches have names.

Krishna's Panchajanya, Arjuna's Devadatta, Bhima's Paundra.

Weapons and instruments being named individually is how epic registers weight. These are not props; each has a story attached, and the naming is the text slowing down before the thing it is about to do.
