Basically Väinämöinen & Joukahainen have an epic song battle. Near the end of the rune/poem, Väinämöinen magically sings Joukahainen into the swamp. Joukahainen offers Väinämöinen many things to stop him from sinking him. But Väinämöinen has no need for his offers and sinks him further into the swamp after each offer. In this point of the illustration, when Joukahainen is desperate, he offers his lovely sister Aino to Väinämöinen to be his bride. This is one of my favorite runes/poems in the Kalevala.
