Rishi: Madhucchandas Vaiśvāmitra (attributed seer for RV 1.1–1.11; for this early Agni/All-gods sequence within RV 1.3, the family attribution remains Vaiśvāmitra in many traditions).
Devata: Viśve Devāḥ (All the Gods) invited to the Soma offering.
Chandas: Gāyatrī (3 × 8 syllables; common in early Mandala 1 invocations).
Samhita Patha (Devanagari)
ओमासश्चर्षणीधृतो विश्वे देवास आ गत । दाश्वांसो दाशुषः सुतम् ॥
Ihr Allgötter, Träger der Menschenwelten, kommt her mit euren schnellen Füllen; dem Gebenden, dem Opfernden ist Soma ausgepresst: trinkt und stärkt das innere Opfer.
