Rishi: Traditional attribution: Agni-hymnic seers (not uniquely determinable from this excerpt alone in VS arrangement).
Devata: Agni / Yajña as the operative divine principle; Vasus as beneficiaries by implication.
Chandas: Mixed/irregular (VS prose-verse compilation; not safely determinable without full pada-metrical control).
Samhita Patha (Devanagari)
स दु॑द्रव॒त्स्वा॒हुत॒: स दु॑द्रव॒त्स्वा॒हुतः । सु॒ब्रह्मा॑ य॒ज्ञः सु॒शमी॒ वसू॑नां दे॒वᳪ राधो॒ जना॑नाम्
Transliteration
sa dūdravat svāhutaḥ | sa dūdravat svāhutaḥ | subrahmā yajñaḥ suśamī vasūnāṃ devaṃ rādho janānām
Translation
Vite cela s’est élancé, dûment offert avec l’appel « Svāhā » ; vite cela s’est élancé, dûment offert avec l’appel « Svāhā ». Le sacrifice est de bonne parole sacrée, très favorable aux Vasus ; (il est) largesse divine pour les hommes.
