Rigveda — Dyáuṣ pitṛ́ attestations (Jamison & Brereton translation)
The standard complete English translation of the Rigveda, the oldest Indo-Aryan text corpus. For the sky-father motif it supplies the Vedic member of the cognate formula: Dyáuṣ pitṛ́ ("Father Sky"), invoked in fixed pairing with Pṛthivī mātṛ́ ("Mother Earth") — e.g. the vocative formula dyaúṣ pítar ... pṛ́thivi mātar (RV 6.51.5). The Rigveda is the vault's canonical case of the composition-vs-attestation problem: composed c. 1500–1200 BCE on linguistic grounds, but transmitted orally with mantric exactitude and physically attested only in medieval manuscripts (oldest reported c. 1040 CE, Nepal, per Witzel 1997; oldest securely documented 1464 CE, BORI Pune). The manuscript record is reconciled vault-wide in rigveda-oral-gap-composition-vs-attestation and rigveda-oral-composition-attestation-gap.
Dyáuṣ pitṛ́ / dyaúṣ pítar appears across the family books (e.g. RV 6.51.5; cf. 1.89.4, 1.90.7, 1.164.33 "Dyaus is my father, my begetter; my mother is this great Earth") — the Sanskrit half of the Zeû páter / Iūpiter equation (Jamison & Brereton 2014, ad locc.).
Dyaus is a marginal figure in the working Rigvedic pantheon — no hymn cycle of his own, eclipsed by Indra (who in some passages supplants or defeats his father) — important for the question of why inherited gods fade while the inherited name formula survives.
The oral-transmission fidelity of the Rigveda (multiple redundant recitation modes) is the scholarly basis for trusting a Bronze Age composition date despite medieval manuscripts.
Linguistic dating (c. 1500–1200 BCE) is inference (class-3-adjacent), anchored externally by the Mitanni treaty theonyms (c. 1380 BCE: Mitra, Varuṇa, Indra, Nāsatyas in a dated cuneiform document) showing Vedic-type religion already existing then — though Dyaus himself is not among the Mitanni gods. Jamison & Brereton is the current standard; older translations (Griffith 1896) are unreliable for load-bearing claims.
