Sky-and-fire god; heavenly smith; father of Dazbog (the sun-god). The Hypatian Codex Greek-translation interpolation equates Svarog with Hephaestus and identifies Dazbog as Svarog's son — preserving the Slavic Svarog-Dazbog father-son theological structure that aligns with the broader Indo-European sky-father-and-sun-son complex. Not in Vladimir's 980 CE Kiev pantheon-hill (which lists only Dazbog the son, not Svarog the father), but Svarog-cult is attested in West Slavic territories through the Polabian Svarožič cult at Rethra (destroyed 11th-c. Christian conquest) and in East Slavic chronicle interpolations. The etymology is contested between native Proto-Slavic *svar- "to forge, to weld" (matching the heavenly-smith domain) and an Indo-Iranic loan from Sanskrit svarga "heaven" (Vasmer 1953-1958), with the loan-reading suggesting Scythian-Sarmatian intermediary contact during the early-Slavic-formation period. Per some Slavic folk traditions, Svarog dropped the first plow from heaven, teaching humanity agriculture — paralleling the Greek cultural-gift mythologem. The registry treats Svarog as deity with parentIds=[] and Dazbog as standalone-deity (not registered in this 6-entry budget) with the father-son relation documented in entry notes; the strict-pass implications of the Svarog-Dazbog parentage chain are deferred for potential future deepening.
