Dazhbog is a solar god and one of the seven idols Vladimir erected in Kiev in 980 according to the Primary Chronicle, and one of the very few Slavic gods whose worship is attested across the Slavic lands. The Primary Chronicle's 1114 entry, following the Slavonic translation of John Malalas, makes him the son of Svarog and says he was called the Sun, and The Tale of Igor's Campaign calls the Rus 'Dazhbog's descendants'. Whether he was the sun itself, a giver of wealth, or a culture hero is disputed, because no narrative of him survives.
Modern Practice
Dazhbog is met at sunrise and at harvest: bread from the first grain, honey, and the sun faced rather than addressed indoors. The practice is gratitude and increase - the giving god is thanked for what is given, not petitioned for a bargain - and the horse and the coin are his older signs.
