The name Svarogs is mentioned in the Slavic translation of the Byzantine Chronicle of John Malalas , where the scribe compares him in a gloss with the Greek fire god Hephaestus . He is said to have introduced monogamy , the punishment for violations was death in a fiery furnace. His son and successor Svarožić guarded this law.
Linguistically, the name of the god can be combined with the term for "heaven" (in the sense of paradise ) in Sanskrit , स्वर्ग svargá- (m.).
